Abstract Background Traditional plant protection strategies have an integral part of food production system in North Eastern state Tripura, India, which has bestowed with rich heritage and biodiversity. However, there is no comprehensive report on the indigenous plant protection practices (IPPPs) specific to insect and vertebrate pest management, being followed by the inhabitants of the region for centuries. The present study was conducted to investigate, collect, and document the vulnerable IPPP practices followed by the native people from far flung locations of the Tripura. Methods The study aimed to document the IPPP following semi-structured questionnaires, participatory interaction, and direct observations with a total of 200 informants. We have calculated the relative frequencies of citation (RFC) for IPPP and estimated principal component analysis to link the status of IPPP with socio-demographic factors of the informants. The relationship between the field of IPPP used and different covariates (age, education, occupation, gender, location, and house type) was assessed using the Kruskal–Wallis test and Chi-square test. The relationship between adoption level and the respondents’ characteristics was analyzed using count regression analysis. Results The study found that the status of the IPPP has increased for mitigating pest issues. A total of 39 indigenous practices were recorded specifically to pest management from the ethnic people of Tripura, India. People acquired pretty knowledge about IPPP, and these were inherited from ancestors. The respondents in the study developed notable innovations for the management of many pest issues using locally available resources that warrant cost-effective and eco-friendly. Seed drying before storage to protect grain commodities was the most cited IPPP with a frequency of citation 0.675. In the field of IPPP used, the people primarily practiced agriculture + horticulture + storage category. An important implication from the study is the identification of two IPPP strategies in this region for the first time. Furthermore, the recorded IPPP used field was significantly associated with age, education, occupation, gender, locality, and house type. Likewise, the respondents’ socio-demographic variables were coupled considerably with the adoption of specific IPPP. Conclusion The reported IPPP for alleviating pest problems reflects the wisdom and generosity of the ethnic growers of Tripura, India. The study suggests the IPPP has strong potential in an integrated pest management approach passed down from generation to generation. The vulnerable practices largely remained unexplored due to inadequate scientific scrutiny and authenticity, yet in danger of being lost if not documented systematically. This study provides the first step toward accessing the valuable technology of untapped Tripura in IPPP and could be viable in paving action paradigm for their preservation, diffusion, and application with advanced pest management options.

Abstract Mango farmers in Ghana are confronted with many pest problems like fruit flies, Sternochetus mangiferae (F.), and mealy bugs. Different pest management options are available to mango farmers; however, the extent to which they apply the available pest management options is not well known. A survey was conducted among 60 farmers in southeastern Ghana, from October–December 2015 mango season, to find out the level of knowledge and practice of insect pest management used by mango farmers. The results showed that most farmers use conventional insecticides to control insect pests in mango. Majority of the farmers (30%) use a composite insecticide (Cydim super; 36 g cypermethrin + 400 g dimethoate per liter), whereas 3.3% use Pyrinex (chlorpyrifos 480 g/liter). Majority of insecticides used belong to WHO category II. Ninety percent (90%) of the farmers use cultural practices and pheromone traps. Pheromone traps are, however, used for fruit flies but not for S. mangiferae. Over 80% of the respondents who used pesticides to control pests have also adopted GLOBALGAP standards for certification. The results are discussed based on the importance of adoption of IPM strategies in mango production and the possible reduction of fruit rejection during mango export in Ghana.

A participatory, on-farm research and extension program has been established around 16 demonstration comparisons of biologically integrated soil building–pest management systems and conventionally managed systems within the West Side row crop area of California's San Joaquin Valley. In each of the biologically integrated parcels, cover crops and composted organic materials are integrated into rotations wherever appropriate, whereas in the conventionally managed parcels, mineral fertilizer applications are made. Pest management practices are evaluated and biologically and informationally intensive alternatives are developed through a participatory process. Indices of soil quality including nutrient status, water stable aggregates, organic matter content, and phospholipid fatty acids are routinely monitored. Information related to the objectives, structure and monitoring activities of this project during the establishment phase will be discussed.

AbstractSimulated windrow experiments revealed that 32.0 ± 8.4% or 3rd-instar Agromyza frontella (Rondani) larvae completed development and formed puparia in alfalfa hay during field curing; 1st- and 2nd-instar larvae suffered almost complete mortality. Under a management schedule where first harvest was at 10% bloom, adult emergence was 45% higher from soil under windrowed hay than from soil under strips immediately raked. Development of A. frontella in hay being field-cured is discussed in relation to crop pest management and crop management options.

Crude powders of Azadirachta indica, Lantana camara, and Tephrosia vogelii, each at six concentrations (0.0, 2.0, 4.0, 6.0, 8.0, and 10% w/w), and Actellic Super<sup>TM</sup> 2% dust were evaluated for repellence anti-feeding and toxicity to adult Prostephanus truncatus. Treatments were laid out in a completely randomised design with four replicates. Results showed that powders were strongly repellent (PR values 73.0&ndash;90.0%) and caused 46.2&ndash;52.2 and 69.7&ndash;85.6% reductions in grain damage and F<sub>1</sub> progeny, respectively. Results showed that powders were weakly toxic to P. truncatus causing 40% kill 21 days after treatment compared to 100% kill by Actellic Super<sup>TM</sup>2% dust 5 DAT. The findings are discussed in the context of their relevance for integrated pest management options in smallholder agriculture.

Indirect effects of insect control strategies on weed populations are important to consider when developing robust integrated pest management strategies. Weed seed predation rates were investigated in corn managed under three contrasting treatments based on control practices for corn rootworm: (1) the transgenic crop Cry3Bb Bt corn, (2) the broad-spectrum insecticide tefluthrin, and (3) no insecticide control. This 2-yr field study conducted near Ithaca, NY, involved quantifying seed loss from velvetleaf, common lambsquarters, and giant foxtail in arenas with and without vertebrate exclosures. Velvetleaf and giant foxtail were unaffected by the insecticide treatment; however, average seed predation of common lambsquarters was lower in both the Bt corn (11.9%) and insecticide-treated plots (11.8%) compared with control plots (17.5%) that did not receive any insecticide. Seed predation of common lambsquarters was not affected by the vertebrate exclosure. Lower seed predation in the transgenic Bt corn and insecticide treatments was likely due to nontarget effects on carabids (Coleoptera: Carabidae). Although the reduction in seed predation was modest and limited to only one of the three weed species tested, our results highlight the need for greater risk assessment that includes the ecosystem service of weed seed predation when considering insect pest management options.

Abstract This paper provides an overview of CONESYS, a computer software package designed to assist seed orchard managers to collect, process, and store information about the quality and quantity of seed orchard crops. CONESYS also contains a database on cone and seed insects, registered pest control products and their efficacy, and a decision support program that determines the costs and benefits of various pest management options.
