Cowpea (Vigna unguiculata) is an important legume which is consumed globally for protein intake, particularly in Asian states. It is a well-known source of dietary fiber, protein, minerals, and vitamins. The cowpea grains are stored after harvest and used till the next harvest. However, the grains are infested by storage pests, primarily Callosobruchus maculatus. Hence, effective management strategies are needed to protect the stored grains form the pests. This study assessed the efficacy of some edible oils in suppressing C. maculatus infestation in stored cowpea grains. Four different botanical oils (i.e., mustard, neem, poppy, and pumpkin) at four different concentrations (i.e., 0.5, 1.0, 1.5 and 2.0 ml per 100 g grain) were included in the study. A control treatment without any botanical oil was also included for comparison. The relevant concentrations of botanical oils were poured into plastic containers containing 100 g cowpea grains and ten C. maculatus adults were released. The jars were sealed and placed at room temperature. Data relating to mortality, oviposition, F1 adult emergence, and seed weight loss were recorded. The tested botanical oils and their concentrations significantly affected mortality after one day. Mortality after 2nd and 3rd days remained unaffected by botanical oils and their different concentrations. The highest mortality was recorded in neem oil-treated grains followed by poppy, pumpkin, and mustard oils. Increased oviposition rate was observed in the grains treated with mustard and pumpkin oils, while those treated with neem and poppy oil recorded decreased oviposition. The control treatment had increased oviposition rate compared to tested botanical oils. All botanical oils significantly inhibited egg laying percentage. The highest germination was recorded for the grains treated with mustard oil followed by pumpkin, poppy, and neem oils, respectively. The lowest germination was recorded for control treatment. Significant differences were noted for C. maculatus repellency among botanical oils. No emergence of adults (F1 progeny) was recorded in all tested botanical oils; thus, F1 progeny was inhibited by 100%. Weight loss, damage percentage, and holes in the grains were not recorded since F1 progeny did not emerge. It is concluded that tested botanical oils are promising and could be utilized to control C. maculatus in cowpea grains during storage.

The present investigation was carried out to evaluate the efficacy of some botanicals as grain protectant against Caryedon serratus (Oliver) in stored groundnut at Prayagraj during 2019 to 2020. Seven botanicals viz., Neem oil, castor oil, neem leaf powder, turmeric rhizome powder, lantana leaf powder, mint leaf powder, tulsi leaf powder were evaluated as compared to control on the basis of adult mortality (%), number of adult emergence and weight loss (%) in stored groundnut. The results showed that neem oil was more effective followed by castor oil, neem leaf powder.

“…The present findings agree with those of Khan et al (2015) on neem leaf powder @ 2.5 g/ kg mungbean as regards damage and weight loss. Kumar et al (2017) reported that treatment of grains with neem oil, mentha oil and lemongrass oil @ 2.5 ml/ kg seed were very effective.…”

Efficacy of some seed protectants against pulse beetle Callosobruchus chinensis (L.) in stored mungbean variety MH 421 was evaluated under laboratory conditions in the Department of Entomology, CCSHAU, Hisar during October-December 2018. The result revealed that the neem leaf powder (30g/ kg) and neem oil (10 ml/ kg) were found most effective with maximum adult mortality (100 and 98.33%, respectively), lowest grain damage and weight loss (1.06 and 1.20%) and (0.75 and 0.81%, respectively), followed by mentha oil (2.5 ml/ kg) and lemongrass oil (2.5 ml/ kg). Turmeric powder resulted in only less adult mortality (48.33%) with maximum infestation and weight loss (14.66 and 4.13%, respectively).
