Abstract
Tribolium castaneum (Herbst) is a
highly detrimental insect pest of wheat, causing critical damage to a diverse
variety of precious food products during storage. It is a globally distributed
insect pest with remarkable adaptability to survive in diverse atmospheric
conditions. Synthetic insecticides and fumigation have been the major choices
for insect pest management on a global scale. However, the utilization of
chemicals results in adverse consequences for both environmental ecosystems and
human well-being. Consequently, the exploration of sustainable options has
become a critical need in recent times. This study aims to promote insect pest
management using biological approaches. To accomplish this objective,
laboratory experiments were undertaken to assess the efficacy of neem (Azadirachta
indica) and its derivatives, viz., bark, seed, leaf and flower against Tribolium
castaneum (Herbst). The assessments were made by measuring the percentages
of adult mortality and adult emergence. The findings of this study revealed
that each treatment efficiently induced adult mortality and significantly
reduced the percentage of adult emergence in comparison to the control.
Subsequently, neem seed powder was found to be superior among treatments,
exhibiting the highest adult mortality and the lowest percentage of adult
emergence, followed by neem leaf, neem bark, and neem flower. The present
investigation demonstrated that neem and its derivatives exhibit insecticidal activities,
thereby emerging as a potential alternative for synthetic pest management
techniques.
