However, their populations are increasingly threatened, primarily due to exposure to pesticides, particularly organophosphates, commonly used in agriculture for pest control. In this study, insecticides including chlorpyriphos 20 EC, dimethoate 30 EC, and profenophos 50 EC were evaluated at various concentrations (0.005% to 0.09%) through topical and oral application methods. Results showed significant mortality in experimental bees across all concentrations of the insecticides, with higher mortality observed in oral exposure. Mortality increased with concentration and time, with chlorpyriphos 20 EC exhibiting mortality percentages ranging from 6.67% to 100%, dimethoate 30 EC from 0.00% to 100%, and profenophos 50 EC from 8.33% to 100%. Toxicity assessment revealed lowest LC50 values in chlorpyriphos 20 EC (0.008) and dimethoate 30 EC (0.007) through topical and oral methods at 24 hours after treatment (HAT), respectively. Relative toxicity, extrapolated from LD50 values, was highest in chlorpyriphos 20 EC (1.62) and dimethoate 30 EC (1.85) through topical and oral methods at 24 HAT, respectively. Profenophos 50 EC exhibited the lowest safety index (0.26) through topical application and dimethoate 30 EC (0.23) through oral application at 24 HAT. Overall, the study highlights the negative impact of insecticides on A. mellifera and underscores the urgent need for a comprehensive evaluation of the risks posed by current pest control practices to honey bees and other essential pollinators.

Higher dose of imidacloprid 17.8 SL (0.45ml) was most effective in reducing population of white fly and melon aphid and increasing mortality (89.03% and 88.15%) after two sprays on sponge gourd respectively. Imidacloprid 17.8 SL (0.3ml) and dimethoate 30 EC (1ml) recorded mortality percentage of 75.21 and 75.05 (white fly) and 78.02 and 77.75 (melon aphid). These insecticides were at par with each other but significantly different from imidacloprid 17.8 SL (0.45 ml), dichlorvos 76 EC (1ml), chlorpyriphos 20 EC (1 ml), imidacloprid 17.8 SL (0.15 ml) and neem oil (2 ml) recorded mortality percentage 60.75, 54.73, 36.02 and 34.81 (white fly) and 69.58, 63.62, 45.88 and 36.60 (melon aphid), respectively. These treatments were significantly different from other treatments and were superior over control.

Of these A. fabae, B. tabaci and Conapium sp. indet. were categorized as major pests as they caused significant damage. The incidence of these pests showed a peak on the 35th standard meteorological week (SMW) in all the three locations studied. The peak incidence at Bandipora was 11.80 ± 0.66, 3.10 ± 0.58 and 1.20 ± 0.08, respectively; at Baramulla, the peak was 10.40 ± 0.62, 3.40 ± 0.13 and 1.30 ± 0.07, respectively; and at Kupwara, it was varying as 12.60 ± 0.69, 3.40 ± 0.13 and 1.30 ± 0.07 for the three pests, respectively.

The peaks in incidence were observed in 34th SW (T. vaporariorum - 12.99 ± 1.18/leaf and A. gossypii- 52.5 ± 9.60/leaf. The incidence of these exhibited a positive correlation with temperature and a negative one with relative humidity. When insecticides were evaluated against these in polyhouse, after two sprays, imidacloprid 17.8SL (0.45 ml) was superior. Imidacloprid 17.8SL (0.3 ml) and dimethoate 30EC (1 ml) provided efficient control.

This resulted in maximum reduction of pests (76.85, 75.43, 69.97% of aphid, whitefly and weevil, respectively) and resulted in maximum gross returns (`₹94,068), net returns (``₹64,017) and benefit cost ratio (2.13). Besides, these effect of intercropping of beans with maize revealed a reduced population density of all the major pests, as compared to sole bean crop.

The commonly cultivated mushrooms include Agaricus, Lentinus, Flammulina, Pleurotusand Volvariella. In India, Button mushroom (Agaricusbisporus)is the most commonly cultivated mushroom followed by Pleurotus(Shah et al., 2013). Mushrooms are mainly subjected to bacterial, fungal and viral diseases. The production of fruiting bodies is severely afflicted by fungal, bacterial and viral pathogens that can cause diseases which have an effect on yield and quality (Potocnik et al., 2008). Improper pasteurization of compost and casing soil can be the major source of diseases. Once the disease is introduced in the farm it can be carried out by the different agencies like air, water, machines and workers (Munshi et al., 2010). Fungal diseases commonly occurring in white button mushrooms include dry bubble (Verticillium spp.), cobweb (Cladobotryumspp.), green mou...
