Integrated pest management approaches against Drosophila suzukii

The appearance of Drosophila suzukii in 2009 has strongly affected the cherry cultivation. Prior to SWD invasion, Italian cherry orchards were treated with only two insecticide applications, the first against aphids (Myzus cerasi Sulz.) before flowering and the second against Rhagoletis cerasi, about 20-30 days before harvest. After D. suzukii invasion, additional two-three pre-harvest (close to harvest) insecticide treatments are required, but the number of insecticide applications can increase to 5-8 depending on pest abundance, crop susceptibility and other environmental factors. The intensive use of insecticides poses serious concerns about the presence of residues on fruits exceeding maximum residue limits (MRLs), the development of resistance, and negative impacts on the environment beyond beneficials. To obtain a good and sustainable control of D. suzukii the chemical strategies should be coupled with cultural management the use of nets and parasitoids. To achieve good control of the carpophagus it is essential to monitor, as well as the adults with trap lured with blends of fermentig substances, the oviposition on the ripening fruit, because the percentage of infestation is not related to the number of catches in the food traps. Considering the viability of SWD eggs and larvae is lower under dry, warm conditions, cool humid microhabitats should be avoided by pruning to open up the canopy in order to increase airflow on the trees and reduce shading. In addition, the use of mulches reducing standing water can further contribute to the reduction of humidity in fruit orchards. Precision irrigation should also be incorporated to reduce pooling of water on the ground. Mass trapping, placing numerous traps around the perimeter outside fruit fields, is suitable and cost-effective method only for cultivations where the pest pressure is considerably low, if necessary insecticides could be applied to the surface of the traps to function as an attract-and-kill strategy. Among the sustainable protection techniques for the control of D. suzukii, the use of insect-proof nets has proved effective, reducing or completely replacing the use of insecticides in some instances, and providing high levels of exclusion of D. suzukii from the crop. During the ripening season, sanitary measures such as removal of dropped, infested and over-ripe fruits is suggested. The collection and treatment of infested fruit through sun exposure, disposal in closed containers, crushing, low temperature treatments, bagging and burying, to destroy D. suzukii eggs and larvae are Fig. 6 - Tecniche di produzione integrata per il contenimento di Drosophila suzukii Fig. 6 - Integrated production techniques for Drosophila suzukii control Integrated pest management against D. suzukii 73 essential IPM procedures to limit the infestation of healthy fruit. The augmentative release of parasitoids and conservation biocontrol of generalist predators, potentially, could contribute to the integrated management of D. suzukii populations, especially in natural habitats close to commercial crops, however further work on the effectiveness of native parasitoids and generalist predators in Europe and the USA, in the field, is required. In this paper, the integration of different tools for D. suzukii control will be discussed, in order to develop effective, eco-friendly and practical strategies in the management of the pest on cherry

AbstractThree species of ambrosia beetles (Trypodendron lineatum (Olivier), Gnathotrichus sulcatus (LeConte), and G. retusus (LeConte) (Coleoptera: Curculionidae: Scolytinae)) have been estimated to cause annual losses of $95–$189 million in degrade of logs and lumber on the British Columbia coast, in Canada. A consultant-run semiochemical-based integrated pest management programme was implemented in 1982 against these beetles, following fulfilment of four prerequisites: (1) presence of receptive potential clients, (2) availability of semiochemical lures, (3) invention of an operational trap, and (4) proof of concept of mass trapping technology. The programme is based on two broad strategies: maintain the problem at a tolerable level and, if necessary, reduce the problem to a tolerable level. One measure of effectiveness over 12 years of mass trapping at a dryland sort near Sooke, on Vancouver Island, British Columbia, was 16.4 million beetles trapped and an estimated five to one benefit-to-cost ratio. Despite success, several factors have conspired to reduce the programme from 50 sites serviced in early years to 7 in 2018. Timber companies in British Columbia are currently showing renewed interest and are taking steps to incorporate the integrated pest management programme as a formal component of their overall operations.

New techniques for Ceratitis capitata (Wiedemann, 1824) control are being studied and developed to replace traditional organophosphate pesticide applications. A mass trapping strategy offers promising medfly control within integrated pest management (IPM) programmes. Field assays were performed to study the efficacy of two mass trapping techniques based on PheroNorm® and Ceratrap® lures that were compared to a conventional approach to control the medfly in Tunisian apricot orchards. The results showed that both mass trapping techniques had a similar efficiency in reducing the C. capitata population. The degrees Brix in the fruits was a determinant issue since the initial apricot fruit damage was detected at 6.4%. At harvesting, the lowest fruit damage rate was recorded in the PheroNorm® (4.25%) and Ceratrap® (6.50%) treated orchards, compared with the conventional approach (10.75%). Therefore, the use of 50 PheroNorm® and Ceratrap® traps per ha density within an IPM approach may be very useful to control the C. capitata populations in apricot orchards.

Management Tools

Bacillus-based biological control agents (BCAs) have great potential in integrated pest management (IPM) systems; however, relatively little work has been published on integration with other IPM management tools. Unfortunately, most research has focused on BCAs as alternatives to synthetic chemical fungicides or bactericides and not as part of an integrated management system. IPM has had many definitions and this review will use the national coalition for IPM definition: “A sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimizes economic, health and environmental risks.” This review will examine the integrated use of Bacillus-based BCAs with disease management tools, including resistant cultivars, fungicides or bactericides, or other BCAs. This integration is important because the consistency and degree of disease control by Bacillus-based BCAs is rarely equal to the control afforded by the best fungicides or bactericides. In theory, integration of several tools brings stability to disease management programs. Integration of BCAs with other disease management tools often provides broader crop adaptation and both more efficacious and consistent levels of disease control. This review will also discuss the use of Bacillus-based BCAs in fungicide resistance management. Work with Bacillus thuringiensis and insect pest management is the exception to the relative paucity of reports but will not be the focus of this review.

Coffee (Coffea sp.) Is a crop of great economic relevance, it stands out as one of the most important agricultural commodities for the country. As with any other high value-added crop, coffee crops suffer from the attack of many pests, and proper management of these pests is critical to successful production. Integrated Pest Management (IPM) is a pest management system that associates the environment and population dynamics of the pest, considers the use of all available plant protection methods and the integration of appropriate measures to maintain the population level of thepest below the level of damage in an economically, environmentally and ecologically viable way. The purpose of this literature review was to gather information on research involving the integrated management of pests in the coffee crop.

En la última década, por su amplia distribución mundial, selectividad y efectividad en el control de insectos plaga, organismos como los nematodos que parasitan insectos (entomonemátodos) han jugado un papel fundamental como herramientas del control biológico en programas de manejo integrado de plagas (MIP). El objetivo del presente trabajo fue evaluar el efecto de Steinernema sp. sobre larvas de Ancognatha scarabaeoides en laboratorio e invernadero. El nematodo se obtuvo de larvas infectadas por A. scarabaeoides encontradas en campo en los municipios de Yacuanquer y Ospina (Nariño, Colombia) una importante zona productora de papa. Para la evaluación de eficacia in vitro, se colocó una larva de A. scarabaeoides en una suspensión de 3 ml de nematodos a diversas concentraciones (1, 5, 15, 30, 50, 100 y 150 nemátodos/ml). El porcentaje acumulado de mortalidad de las larvas de A. scarabaeoides 18 días después de la inoculación fue de 100% y 90% con las concentraciones de 150 y 100 nematodos/ ml respectivamente y a una concentración letal 90 (CL90) de 87 nematodos/ml. En invernadero Steinernema sp. se evaluó a las concentraciones letales 50 (CL50) y 90 (CL90), presentando a los 15 días de aplicados los tratamientos porcentajes de mortalidad de larvas de 33,3% y 79,3%, respectivamente. Este resultado abre la posibilidad de incluir este biocontrolador nativo en el manejo integrado de chisas en el departamento de Nariño. The effect of Steinernema sp. entomonematode on Ancognatha scarabaeoides grubs (Coleopter: Scarabaeidae) in laboratory and greenhouse conditionsOrganisms such as parasitic insect nematodes have played a fundamental role as biological control tools in integrated pest management programmes (IPM) during the last decade due to their broad world-wide distribution, selectivity and effectiveness in controlling insects. The present work was aimed at evaluating the effect of Steinernema sp. on Ancognatha scarabaeoides grubs in laboratory and greenhouse conditions. The nematode was obtained from infected A. scarabaeoides grubs found in the municipalities of Yacuanquer and Ospina (Nariño department, Colombia), an important potato growing area. An A. scarabaeoides larva was placed on damp filter paper in a 3 ml nematode suspension at different potato inoculation concentrations (1, 5, 15, 30, 50 and 100 nematodes/ml) for evaluating in vitro efficacy in the laboratory. There was 100% and 90% accumulated A. scarabaeoides grub mortality 18 days after inoculation with 100 and 150 nematodes/ml concentrations, respectively, at 87 nematodes/ml lethal concentration 90 (CL90). The Steinernema sp. entomonematode was evaluated at 50 (CL50) and 90 (CL90) lethal concentrations in greenhouse conditions, presenting 33.33% and 79.3% grub mortality, respectively, after 15 days of applying the treatments. This result indicates that this native bio-controller could be included in white grub integrated management in the Nariño department of Colombia.

<abstract>Spraying insecticides and releasing natural enemies are two commonly used methods in the integrated pest management strategy. With the rapid development of biotechnology, more and more realistic factors have been considered in the establishment and implementation of the integrated pest management models, such as the limited resources, the mutual restriction between pests and natural enemies, and the monitoring data of agricultural insects. Given these realities, we have proposed a pest-natural enemy integrated management system, which is a nonlinear state-dependent feedback control model. Besides the anti-predator behavior of the pests to the natural enemies is considered, the density dependent killing rate of pests and releasing amount of natural enemies are also introduced into the system. We address the impulsive sets and phase sets of the system in different cases, and the analytic expression of the Poincaré map which is defined in the phase set was investigated. Further we analyze the existence, uniqueness, global stability of order-1 periodic solution. In addition, the existence of periodic solution of order-$ k $ ($ k\geq2 $) is discussed. The theoretical analyses developed here not only show the relationship between the economic threshold and the other key factors related to pest control, but also reveal the complex dynamical behavior induced by the nonlinear impulsive control strategies.</abstract>

Since the identification of the Ectropis grisescens sex pheromone, no effective control technology based on this pheromone has yet been developed and evaluated. In this study, pheromone proportion and dosage, sustained-release dispensers, and pheromone lure-matched traps were optimized. The mass trapping technology developed with the above optimized parameters was tested in a field trial. The results show that two compounds, (Z,Z,Z)-3,6,9-octadecatriene and (Z,Z)-3,9-cis-6,7-epoxy-octadecadiene, at a ratio of 30:70 and impregnated into rubber septa at 1 mg, were the most attractive to male moths. These compounds provided the best performance when combined with a sticky wing trap. Adult male moth monitoring data showed that there was a lower population density in the trapping plot compared with the control plot, and there was a clear difference during the peak adult occurrence of the first five insect generations in 2017. The effect of mass trapping on the larva population was investigated in 2018; the control efficiency reached 49.27% after trapping of one generation of adults and was further reduced to 67.16% after two successive adult moth generations, compared with the control plot. The results of the present study provide a scientific basis for the establishment of sex pheromone-based integrated pest management strategies.

Entomological Research

The marking of Drosophila suzukii can be an important instrument for studying the ecology and behaviour of this economically important fruit pest, aiding the development of new Integrated Pest Management (IPM) tools or strategies. There is, however, a need for a cost-effective methodology that provides an easily detectable and stable mark. Whereas fluorescent pigment powders are often used in entomological research, the pigments (series, dyes), application techniques, or doses need to be evaluated for each studied species in terms of their efficacy and possible adverse effects on the performance of the insect. The effectiveness of different application techniques and dyes (RadGlo® TP-series) and their effect on the survival of adult D. suzukii were investigated in the laboratory. Furthermore, the influence of the marking on the behaviour of the flies was examined in laboratory trap assays (olfaction) and a field recapture study (general orientation). The persistence and detectability of the marks was evaluated both on living flies (for different application techniques) and dead flies under trapping/storage conditions. The use of fluorescent powders to mark D. suzukii flies yielded a clearly detectable and highly persistent mark, without any adverse effects on the survival and behaviour of the flies.

Family Based

In the state of Acre, Brazil, family-based agriculture is predominant and although it has less economic impact in relation to large-scale plantations, it is also subject to biological imbalances, such as the attack of pests, generating economic losses for producers. Phytosanitary knowledge in the state is still incipient and becomes an obstacle to production, often resulting in mistaken management decisions. In this context, this work aimed to present a history of research carried out in the field of Agricultural Entomology, especially in the areas of integrated management and biological control of pests of the most relevant crops grown in the Acre state. In this review, 55 scientific papers related to Agricultural Entomology were presented, 23 on new insect records and/or new insect associations with host plants, 16 on insect control using plant extracts from the Amazon region, 13 on integrated pest management and three on bioecology and population dynamics of pests in the state of Acre. Through this review, it is observed that research in the area of Agricultural Entomology in the state of Acre is characterized by basic research (surveys, registration of new species, bioecological and dynamic population studies). However, there has been a notable advance in scientific studies aimed at integrated pest management in the state in the past ten years. Still, there is a need to concentrate efforts on research aimed at prospecting and using Amazonian biodiversity (fauna and flora), which subsidize applied programs for integrated pest management of the main crops grown in the Acre state.
