Summary: The main fruit pests in Brazil, Anastrepha fraterculus (Wiedemann), Ceratitis capitata (Wiedemann), and Drosophila suzukii (Matsumura), show varying levels of susceptibility to selected insecticides. Diagnostic concentrations of the insecticides caused more than 99% mortality for most field populations of each species.

Summary: Continuous use of insecticides to prevent fruit infestation by spotted-wing drosophila (SWD) can increase the risk of resistance development in field populations. However, proactive assessment of resistance risk through laboratory selection can provide valuable information for developing sustainable resistance management strategies for SWD.

Summary: This research aimed to evaluate the effectiveness of five formulated insecticides with different modes of action against Drosophila suzukii. Spinosad was found to be the most effective insecticide, showing high efficacy against all life stages. Additionally, exposure to spinosad and lambda-cyhalothrin reduced egg laying by females. Further studies are needed to validate these findings under field conditions.

Summary: This research found that the activity of crystalline contact insecticides is inversely dependent on the thermodynamic stability of their polymorphs, and manipulating the solid-state structure can enhance efficacy. Crystallography should be central to the development of contact insecticides to overcome insecticide resistance and reduce development costs by repurposing existing chemical agents.

Summary: This study assessed the toxicity of seven synthetic insecticides on the fall armyworm larvae and found that broflanilide and abamectin were the most toxic. The results provide a basis for the development of novel insecticides for controlling fall armyworm populations.

Summary: Two colonies of parasitoid Trichopria drosophilae were studied, one reared on an artificial diet of Drosophila melanogaster and the other reared on fresh banana. The parasitoids reared on fresh banana showed better performance in terms of longevity, adult size, fecundity, and population size, demonstrating their potential for controlling the pest D. suzukii.

Summary: The toxicity and selectivity of newly synthesized lactone derivatives on D. suzukii and its parasitoid are evaluated. Two compounds are found to be effective against D. suzukii with minimal impact on the parasitoid. In silico predictions suggest that these compounds target GABA receptors and TRP channels of D. suzukii.

Summary: This study found that the use of a petroleum-derived spray oil and an organosilicone, nonionic soil surfactant can effectively control annual bluegrass weevil adults. Increased rate, spray application volume, and soil moisture levels positively affected the level of control. However, the organosilicone, nonionic soil surfactant showed inconsistent control levels in laboratory studies and caused phytotoxicity in greenhouse studies. The efficacy of both treatments was not affected by pyrethroid resistance levels in the tested populations.

Summary: This study evaluated the toxicity and repellency effects of 19 essential oils on the spotted wing drosophila. It was found that certain essential oils, such as C. flexuosus and Mentha spp., had high toxicity against the drosophila, while oils from C. verum, C. citratus QT citratus, and C. winterianus showed the highest toxicity in ingestion assays. Residues of C. verum and C. citratus QT citratus reduced oviposition of the drosophila. Furthermore, all essential oils tested exhibited good repellency effects against the drosophila.

Summary: Herbicides are the most widely used category of pesticides in global agriculture, with increasing cases of herbicide-resistant weed biotypes since the late 1950s. Recommended herbicide resistance management strategies have evolved over the past 50 years, with mixtures of pesticides and antibiotics generally more effective than rotations.

Summary: The use of nanopesticides with controlled release, particularly those formulated with graphene oxide and existing pyrethroid pesticides, shows promising potential in pest control and green agriculture. These nanocomposites exhibit temperature-responsive release and high bioactivity against spider mites, making them a valuable tool for practical applications. Their easy preparation and enhanced efficacy compared to individual pesticides further highlight their significance in the field of pest management.

Summary: The study investigated resistance levels to chlorantraniliprole and tetrachloropyramid in 13 populations of Spodoptera frugiperda in China. Results showed low resistance levels to diamide insecticides in China, and differences in relative resistance among populations were not caused by mutations in RyR or its expression.

Summary: Surveillance and determination of pesticide resistance mechanisms are essential for resistance management. The study utilized proteomic analysis to identify protein differences in susceptible and resistant strains of Colorado potato beetle (CPB), revealing a potential connection between C-type lectin (CTL) expression and insect immunity response to toxins. The findings suggest a novel approach for pest management through targeting insect immunity pathways and highlight the adaptability of CPB to various challenges including synthetic insecticides.

Summary: In southern Ontario, emerging pest two-spotted spider mite is becoming a threat to soybean due to warmer, drier weather. Evaluating 18 soybean cultivars revealed some cultivars, such as OAC Avatar, showed partial resistance to TSSM. Isoflavonoid concentrations in leaves had a low but significant positive correlation with TSSM counts and feeding damage.

Summary: This project examined the interaction between soybean aphids and Ontario-grown soybean cultivars to determine which leaf metabolites were most associated with aphid resistance. The study found a low correlation between isoflavonoid leaf concentrations and aphid resistance, but the aphid-resistant cultivars were determined to have lower free amino acid concentrations. Identifying these resistant cultivars is essential for managing aphid populations and improving soybean resistance.

Summary: The study evaluated the antifungal effects of eight Palestinian indigenous plant essential oils on common postharvest pathogens of tomato and strawberry fruits. Thyme, sesame, and sage essential oils exhibited high antifungal activity against Botrytis cinerea, with clove and sage oils inhibiting mycelium growth significantly. Coating fruit with essential oils reduced decay and improved fruit quality, highlighting the potential use of sage essential oil as an alternative to synthetic pesticides for extending shelf life.
