Towards integrated pest management of Thrips tabaci in onions

Populations of onion thrips Thrips tabaci and their natural enemies were monitored in small field plots of onions to which standard insecticide (methamidophos endosulfan and chlorpyrophos) selective insecticide (imidacloprid and spinosad) organic (YR015) insecticide or no insecticide treatments were applied The mean number of thrips per plant was kept below 12 in the standard and selective treatments The numbers of thrips in the organic and no insecticide treatments were comparable reaching over 60 thrips per plant This resulted in increased plant damage and shorter leaves High rainfall in 200102 coincided with a reduction in thrips numbers in untreated plots which peaked at 70 thrips per plant compared with nearly 500 thrips per plant in the drier 200001 season Natural enemies observed in the unsprayed and organic treatments included Ceranisius menes Aeolothrips fasciatum Buchananiella whitei syphids and entomogenous fungi None of these natural enemies increased sufficiently to provide effective thrips control No natural enemies were found in the standard or selective insecticide treated plots

AbstractThrips tabaci Lindeman is a cosmopolitan and polyphagous insect pest. It is known worldwide and recorded on more than 300 plant species. T. tabaci is a key pest of onion and several other crops, and its control is vital to the production and profitability of crops. If onion thrips population is not controlled, damage can reduce yield volume and quality. In addition to direct damage to the host plants, T. tabaci has been characterized as an asymptomatic vector of three devastating tospovirus species, such as Tomato spotted wilt virus, Iris yellow spot virus, and Tomato yellow ring virus. For this reason, several synthetic insecticides were used for control. However, these insecticides bring unwanted effects, like pesticide resistance, elimination of nontarget species, environmental pollution, and threats to human health. To solve the negative consequences of insecticides, biopesticides, such as plant secondary metabolites, entomopathogenic viruses, bacteria, fungi, and nematodes, have been recognized as effective alternatives. The use of plant-based insecticides and entomopathogenic control methods gained more attention in integrated pest management. Their strong side is lack of residues, saving beneficial insects and minimizing air and water pollution. Plant-derived compounds and entomopathogenic biological control agents offered a variety of biological modes of actions against onion thrips, such as repellency, feeding deterrence, anti-oviposition, fecundity deterrence, metamorphosis inhibition, and parasiting the host’s body.

Population Suppression

Intercropping of aromatic plants provides an environmentally benign route to reducing pest damage in agroecosystems. However, the effect of intercropping on natural enemies, another element which may be vital to the success of an integrated pest management approach, varies in different intercropping systems. Rosemary, Rosmarinus officinalis L. (Lamiaceae), has been reported to be repellent to many insect species. In this study, the impact of sweet pepper/rosemary intercropping on pest population suppression was evaluated under greenhouse conditions and the effect of rosemary intercropping on natural enemy population dynamics was investigated. The results showed that intercropping rosemary with sweet pepper significantly reduced the population densities of three major pest species on sweet pepper, Frankliniella intonsa, Myzus persicae, and Bemisia tabaci, but did not affect the population densities of their natural enemies, the predatory bug, Orius sauteri, or parasitoid, Encarsia formosa. Significant pest population suppression with no adverse effect on released natural enemy populations in the sweet pepper/rosemary intercropping system suggests this could be an approach for integrated pest management of greenhouse-cultivated sweet pepper. Our results highlight the potential of the integration of alternative pest control strategies to optimize sustainable pest control.

Abstract The sugarcane borer, Diatraea saccharalis (F.), is the primary pest of sugarcane, Saccharum spp., in Louisiana. Recent evidence suggests an integrated pest management (IPM) program has reduced the pest’s impact, but the success of this program has not been assessed across the industry. The level of D. saccharalis injury present at harvest was recorded from 388 billet samples from five sugar mills from 2017 to 2019. These results were used to estimate direct and indirect revenue losses from D. saccharalis on the Louisiana sugarcane industry. Insecticide use records were used to estimate control costs and determine total economic impact. The mean percentage of bored internodes was 1.1, 0.3, and 1.7% for 2017, 2018, and 2019, respectively. Direct losses from reduced sugar yield averaged US$4.6 million across years. Indirect losses across years accounted for US$3.0 million and $463,000 for insecticidal control costs and reduced milling efficiency, respectively. The total economic impact of D. saccharalis averaged $8.0 million annually during the three-year study period. This study demonstrates the efficacy of pest management implementation in reducing D. saccharalis injury and highlights the value of IPM. Our findings provide new support for the emergence of D. saccharalis management in the Louisiana sugarcane industry as a modern IPM success story.

The objective of this work was to evaluate the impact of integrated pest management (IPM) in the productivity of the tomato and in the populations of leafminers, fruit borers, and natural enemies in tomato crops. The treatments were calendar (spraying twice weekly with insecticides and fungicides), IPM (spraying when action thresholds were achieved), and control (no pesticide was applied). IPM was the most efficient system of pest control due to presenting similar productivity and 65.6% less pesticide applications than in the calendar. The attack of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) and Liriomyza spp. (Diptera: Agromyzidae) to the leaves only achieved the action threshold in the final phase of the cultivation. The main fruit borer was Neoleucinoides elegantalis (Guen.) (Lepidoptera: Crambidae), followed by T. absoluta and Spodoptera eridania (Cr.) (Lepidoptera: Noctuidae). The natural enemy populations were severely reduced by excessive pesticide applications. Predators were more abundant than parasitoids. The most abundant predators were Araneidae, Anthicus sp. (Coleoptera: Anthicidae), Cycloneda sanguinea larva (L.) (Coleoptera: Coccinellidae), Staphylinidae adults (Coleoptera), Orius sp. and Xylocoris sp. (Hemiptera: Anthocoridae), Formicidae (Hymenoptera), and Phlaeothripidae (Thysanoptera). The most abundant parasitoids were Hymenoptera of the families Eulophidae, Braconidae (Bracon sp. and Chelonus sp.), Trichogrammatidae [Trichogramma pretiosum (Riley)] and Bethylidae (Goniozus nigrifemur Ashmead), besides Tachinidae (Diptera).

En el presente estudio se colectaron cuatro parasitoides de Dasiops inedulis Steyskal (Diptera: Lonchaeidae), i.e., uno de tipo larva-pupa identificado como Utetes anastrephae (Viereck) (Hymenoptera: Braconidae), y tres parasitoides de pupas identificados como Pachycrepoideus vindemmiae Rondani, Spalangia sp. (Hymenoptera: Pteromalidae) y Aganaspis sp. (Hymenoptera: Figitidae). En el campo se observaron daños ocasionados por una larva de Chrysopidae (Neuroptera) sobre pupas centinelas deD. inedulis. Se realizaron experimentos con un cebo tóxico de origen natural a base de Saccharopolyspora spinosa en los municipios de Palmira y Toro, en el departamento del Valle del Cauca, destacándose como una nueva alternativa para el control de D. inedulis en maracuyá amarillo, ya que en las dos localidades mantuvo los niveles de daño por debajo del manejo convencional del agricultor y el testigo absoluto. Se provee una lista de enemigos naturales de D. inedulis tomada mediante muestreos de botones florales de maracuyá, uso de pupas centinelas, e información en la literatura científica. Para el control de la mosca del botón floral del maracuyá, D. inedulis, se propone una estrategia de manejo integrado de plagas que le permitirán al productor mantener las poblaciones de D. inedulis reguladas con diferentes herramientas, i.e., enemigos naturales que se pueden incorporar en diferentes etapas de la fenología de D. inedulis, uso de cebos tóxicos de baja toxicidad, recolección de botones con síntomas de daño, y monitoreo con el uso de trampas McPhail cebadas con proteína hidrolizada, interviniendo en diferentes estados de desarrollo, cortando ciclos y disminuyendo así futuras generaciones del insecto. Integrated pest management as a strategy to control the passionfruit flower-bud fly, Dasiops inedulisSteyskal (Diptera: Lonchaeidae) Four parasitoids of the passion fruit flower bud fly, Dasiops inedulis Steyskal (Diptera: Lonchaeidae) were collected in the present study, i.e., a larva-pupa type parasitoid, Utetes anastrephae (Viereck) (Hymenoptera: Braconidae), and three pupal parasitoids, namely Pachycrepoideus vindemmiaeRondani, Spalangia sp. (Hymenoptera: Pteromalidae) andAganaspis sp. (Hymenoptera: Figitidae). In the field we observed a species of Chrysopidae (Neuroptera) larva feeding on the sentinel pupae of D. inedulis. We conducted experiments in the municipalities of Palmira and Toro, in the State of Valle del Cauca, Colombia, on the efficiency of a toxic bait made from the bacteria Saccharopolyspora spinosa, standing out as a new alternative for controlling D. inedulison yellow passion fruit. This toxic bait maintained the injury levels below the conventional management used by the farmers and the control plots in both study areas. A list of natural enemies of D. inedulis was compiled by inspecting passion fruit flower buds, using sentinel pupae, and information taken from the literature. For the control of D. inedulis, an integrated pest management strategy is proposed that will allow the farmer to maintain D. inedulis populations under control with different management tools, i.e., natural enemies which can be incorporated at different stages of development of D. inedulis, low toxicity baits, recollection of flower buds with symptoms of damage, monitoring with McPhail traps baited with protein hydrolysate, thus intervening at different stages the development of the lonchaeid fly pest, breaking its life cycle and thus decreasing their populations in future generations.
