Abstract Grape berry moths, particularly Lobesia botrana Denis & Schiffermüller (Lepidoptera: Tortricidae), and vinegar flies, such as Drosophila melanogaster Meigen suzukii Matsumura (Diptera: Drosophilidae), are important vineyard pests, causing severe quality loss of grapes. Several arthropod taxa may be involved in the natural control these pests. However, role predators pests remains unclear. We investigated 32 vineyards Palatinate region, southwest Germany, under organic conventional management, which both cases received either full or reduced fungicide applications (2 × 2 design). Predation L. eggs pupae D. on sentinel cards exposed was observed with infrared cameras. In total, nine predator could identified. The most dominant European earwig, Forficula auricularia (Dermaptera: Forficulidae), 90% all predation events. conclude that F. is likely a key special attention should paid to maintain it at high population densities.

The study evaluated the efficacy of insecticides against fall army worm Spodoptera frugiperda (J E Smith) (Lepidoptera: Noctuidae) in sweet corn (Zea mays (L). var. saccharata) and their effects on natural parasitization by Trichogramma sp., a group parasitic wasps known for biocontrol potential. field experiment was conducted rabi 2022-2023 randomized block design. Treatments included seed treatments along with foliar spray sprays alone. Among treatments, treatment cyantraniliprole 19.8% + thiamethoxam 19.8 % FS spinetoram 11.7% SC were found highly effective gave better results lowest leaf injury rating infestation which also reflected grain yield as well, it is par 600 chlorantraniliprole 9.3% +lambda-cyhalothrin 4.6% ZC spray. untreated control recorded highest adult emergence. tetraniliprole ST 480 10.26% OD are safer to Trichogramma.

Anagyrus vladimiri (Hymenoptera: Encyrtidae) is the main parasitoid of Planococcus citri (Hemiptera: Pseudococcidae), which one most important pests citrus crops in Mediterranean Basin. Pesticide residue on trees and nectar wildflowers growing orchards might cause side effects beneficial insects. In present study, we assessed six systemic pesticides (acetamiprid, dimethoate, cyantraniliprole, flupyradifurone, spirotetramat sulfoxaflor) survival progeny A. vladimiri. fed pesticide solutions Fagopyrum esculentum Moench plants that had been watered with a solution containing these pesticides. Acetamiprid, flupyradifurone sulfoxaflor increased female mortality more than control (water) after 6h; consumed pesticides, ranged from 62% to 73%. Cyantraniliprole no immediate toxic effect but caused 15 days. All tested except reduced progeny. After days feeding F. solution, significantly was observed dimethoate (96%), (80%), acetamiprid (62%), cyantraniliprole (62%) (50%). Progeny females treated dimethoate. These results demonstrate some insecticides can have lethal or sublethal by both routes exposure, via direct indirect consumption through plants.

Abstract We investigated the lower thermal limits of Anagyrus vladimiri Triapitsyn (Hymenoptera: Encyrtidae), a natural enemy mealybugs. Parasitoids were cooled to measure supercooling points and lethal temperature LLT 50 . To investigate survival after long-term cold exposure, parasitoid adults eggs, larvae, pupae within their host mummy gradually acclimated. Adults then exposed for three days 7 °C, 5 3 1 immatures varying durations 5, 1, − 4 °C. reproduction. assess impact fluctuating temperature, subjected daily warming 10 °C from baseline temperatures during four-day-cold exposure.
