摘要

Sesame (Sesamum indicum L.), while largely self-pollinated, is significantly benefited from cross-pollination due to its explosive dehiscence mechanism, with non-Apis bees acting as primary pollinators. Despite their importance, traditional pest management strategies often overlook pollinator safety. This study evaluated various pest management modules for controlling Antigastra catalaunalis, a major pest in sesame, and examined their effects on non-Apis bee visitation. Conducted over two years (2022 and 2023) at Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, the study identified twenty-six non-Apis bee species within sesame fields. Four pest management modules were tested: Module-I, II and III had deep ploughing, hand-picking, pheromone traps @4/acre, and bird perches @10/acre in common. However, Module I had alternating sprays (at 15 days interval) of Bacillus thuringiensis and spinosad; Module II had alternate sprays of neem oil (Azadirachta indica) and Beauveria bassiana; Module-III had alternating sprays of emamectin benzoate and chlorantraniliprole; and Module-IV was a control. Module III was statistically superior in reducing A. catalaunalis larval counts (88.22%) and capsule damage (78.78%) but resulted in the lowest non-Apis bee visitation, with a 48.69% reduction compared to the control. In contrast, modules using bio-insecticides (M-I and M-II) had a minimal impact on pollinator visitation. Module-I led to a statistically significant increase in seed yield (467.14% over control), demonstrating its economic superiority (Cost–Benefit Ratio: 1:3.33). This increase in yield was likely attributed to both effective pest control and the conservation of non-Apis pollinators. These findings highlight the importance of incorporating bio-insecticides in pest management strategies to protect non-Apis bees while achieving higher yields.
