Abstract

The biological activity of four spices powder namely black pepper (Piper nigrum L.), black cumin (Nigella sativa L.), methi (Trigonella foenum-graecum) and garlic (Allium sativum L.) was assessed on the basis of adult mortality, oviposition performance, adult emergence of pulse beetle Callosobruchus chinensis L, and seed damage and consequent weight loss of gram (Cicer arietinum) caused by this insect at 0.25 g, 0.50 g and 1.00 g powder/kg gram seeds. All the tested spices powder showed significant effect on the above parameters. The highest adult mortality was recorded when gram seeds were treated with black pepper powder at 1.00 g/kg. whereas methi showed the least effect on adult mortality. Spices powder used in the experiment effectively controlled adult emergence by inhibiting oviposition and growth and development of life stages of pulse beetle. In all the treatments lowest number of adult emergence was obtained from gram seeds treated with black pepper at 1.00 g/kg seeds. The highest weight loss was observed in control treated seeds followed by methi powder at 0.25 g/kg gram seeds. Black pepper treated seeds showed the lowest seed weight loss followed by black cumin, garlic and methi. From this present study the toxicity of the spices powder were found in the order black pepper > black cumin > garlic > methi.

Highlights

Pulse includes beans, peas, lentil, gram and other seeds of pod bearing plant belonging to the family leguminosae which contain high protein ranging from 20-40%
It was reported that only in gram, 55-69% weight loss of seed and 45.6-66.3% loss in protein content was recorded by Callosobruchus chinensis L. [8]
Among the tested spice powders, methi showed the least effect on adult mortality (30.0%) at 0.25 g/ kg gram seeds

Summary

Introduction

Peas, lentil, gram and other seeds of pod bearing plant belonging to the family leguminosae which contain high protein ranging from 20-40%. It has been considered as poor man's meat for the under privileged people who cannot afford animal proteins. The pulse beetles in the genus Callosobruchus (Coleoptera: Bruchidae) are economically important pests of stored pulse seeds [3,4]. It is responsible for an average of 32–64% loss under storage in different parts of Asia and Africa [5,6,7]. It was reported that only in gram, 55-69% weight loss of seed and 45.6-66.3% loss in protein content was recorded by Callosobruchus chinensis L. [8]
