Use of the egg parasitoid, Trichogramma ostriniae (Hymenoptera: Trichogrammatidae) as a biological control agent of the European corn borer, Ostrinia nubilalis (Lepidoptera: Crambidae): An approach to integrated pest management in bell pepper
… Pesticides tested against T. ostriniae were spinosad and methoxyfenozide. Spinosad adversely affected adult T. ostriniae producing 100% mortality at the field rate of 498 mg [AI]/L for both the preimaginal and adult toxicity tests. Use of T. ostriniae can provide effective control of O. …

Monitoring and management of thrips populations in vegetables, row crops, and greenhouse crops in Virginia
… including: essential oils, spinetoram, spinosad, pyrethrins, and azadirachtin, were evaluated in their efficacy against thrips in several different crops. Randomized complete block design experiments were carried out in: tomatoes, snap beans, collards, soybeans, cotton and peanuts grown …

Phenology and Management of Annual Bluegrass Weevil on Virginia Golf Courses
… imidacloprid (IRAC Group 4A: Neonicotinoid), and spinosad (IRAC Group 5: Spinosyn), were tested on ABW adults. In another bioassay, two organophosphates, trichlorfon and chlorpyrifos, resulted in significantly higher ABW mortality rates than all other labeled insecticides (P < 0.0001). Two other …

Combining natural enemies and selective pesticides in IPM programmes of exotic pests: the Tuta absoluta (Lepidoptera: Gelechiidae) case
… thuringiensis proved to be harmless; whereas spinosad, emamectin benzoate and metaflumizone were moderately harmful until 7d after the treatment and abamectin was the most noxious and persistent and was classified as harmful up to 14 days after the treatment. While the other tested pesticides …

Impacts of organic and conventional neurotoxic pesticides on a pest and a pollinator in almond agroecosystems (Prunus dulcis)
… the insecticides acetamiprid, clothianidin, and spinosad (a natural fermentation product made up of a mixture of Spinosyn A and D) were assessed in a series of bioassays with first instar A. transitella larvae from a laboratory strain (CPQ). An increase in the toxicity of acetamiprid and spinosad …

Evaluation of Biopesticides and Novel Chemicals for Grape Ripe Rot and Sour Rot Disease Management in Virginia
… 2022, respectively. In general, treatments with spinosad were less effective and resulted in lower disease control compared to those with zeta-cypermethrin and its fungicides/antimicrobials counterpart. The results suggest that integrating these biopesticides and novel chemicals into a spray …

Ganaspis kimorum as a classical biological control agent for Drosophila suzukii: from laboratory studies to field assessments
… 8). Laboratory topical exposures showed that Spinosad and λ-cyhalothrin were the most toxic active ingredients, while Cyantraniliprole exhibited the least toxicity. Field residual exposures confirmed these findings, with Spinosad and Deltamethrin causing 92% mortality immediately after …

The effectiveness of biological control of Frankliniella occidentalis in prevention of the spread of Tomato spotted wilt virus
… 2) a single chemical treatment with Conserve®, a spinosad formulation, or 3) no treatment. TSWV was introduced into the greenhouse either by starting with 20% of the crop already infected and releasing non-viruliferous thrips, or by making a single release of viruliferous thrips. Analyses were …

Stink bug egg studies in southeastern Virginia: parasitoid survey, and susceptibility and chorion permeability to insecticides
… applications of acephate, lambda-cyhalothrin, spinosad, and thiamethoxam, were carried out to determine efficacy against nonparasitized E. servus and A. hilare eggs, and T. podisi embryos developing in E. servus eggs. Results showed that eggs of both species were susceptible to insecticides, …
