“…There is much research conducted on the use of different insecticides for the management of cowpea weevil in stored grains (Braga et al, 2007;Visarathanonth, Khumlekasing, & Sukprakarn, 1990). Continuous and indiscriminate use of pesticides has not only led to the development of resistant strains but also the accumulation of toxic residues in food grains used for human consumption (Rajapakse, 2006;Said & Pashte, 2015).…”

Food grains infestation by insect pests in stores is a severe challenge in food production around the globe, especially in wet and humid regions. In Bhutan, mung bean is commonly grown for consumption as a superior source of protein. However, severe cowpea weevil infestation is observed while in storage condition. Controlling with synthetic pesticides is associated with health risks due to toxic residues which intervene in safe and healthy protection methods. Protecting the grains in-store through organic approach is imperative for consumption and seed purposes. Some botanical plant extracts are known for their protective properties which need location-specific studies based on availability and suitability. Therefore, this study was conducted to evaluate the efficacy of eight treatments (Acorus calamus rhizome powder, mustard oil, garlic cloves, turmeric rhizome powder, wood ash, Vitex negundo leaf powder, super grain bag including untreated control) against cowpea weevil (Callosobruchus maculatus) in mungbean under storage condition. The experiment was laid in a randomized complete block design with three replications. The result revealed that the lowest mean number of grains perforated and percent grain perforated were recorded in grains treated with Acorus calamus rhizome powder (0.46 & 0.20 %) followed by mustard oil (1.05 & 0.47 %) and grains stored in super grain bag (5.74 & 2.49%), which were significantly lower (P<0.001) as compared to other treatments. The lowest number of adult cowpea weevils was also recorded in grains treated with Acorus calamus and mustard oil followed by grains stored in super grain bag. Germination percentage was found highest in wood ash followed by mustard oil, Acorus calamus and garlic-treated grains while the lowest was in super grain bag. Therefore, Acorus calamus rhizome powder and mustard oil were found to be effective in managing cowpea weevil without affecting seed germination and vigour.

“…Surface and fumigant chemical applications are thought to be the most effective methods for managing bruchid infestations, especially for large scale or extended storage (Rahman, 1990; Visarathanoth et al., 1990; Cardona, 2004; Mbata, 2004). Prohibitive costs and the risk of adverse secondary effects from such treatments have necessitated the exploration of alternative control measures, such as biological control, and the adoption of a more integrated management approach (Brower et al., 1996; Abate et al., 2000; Adebowale & Adedire, 2006).…”

Biological control may provide an affordable and sustainable option for reducing losses to pest Bruchidae in stored food legumes, a crucial source of human dietary protein. Previous investigations have focused primarily on the role of parasitism in bruchid biological control, while the potential of generalist predators has been comparatively unexplored. The true bug Xylocoris flavipes (Reuter) (Heteroptera: Anthocoridae) exhibited a Type II functional response to the majority of cosmopolitan bruchid species evaluated when data were fit to Holling's disc equation. A negative correlation was detected between mean pest species body weight and rate of predation. The rate of attack on adult prey was quite low but fairly consistent, with the larger‐sized female predators generally more effective. The eggs and neonate larvae of Acanthoscelides obtectus Say (Coleoptera: Bruchidae) were the only accessible immature stages among all prey species examined; predation on A. obtectus eggs and larvae was higher than on any adult bruchids. Mean predator kill of A. obtectus immature stages was 40 first instars or 10–20 eggs per 24‐h interval. Further investigation of the biological control potential of X. flavipes against pest Bruchidae is merited due to the predator's ability to kill adult stages of all prey species evaluated.
