Abstract
The aim of this
investigation was to
determine the efficacy of four different kinds of plants extracts, garlic,
onion, castor seeds and neem seeds to protect the stored mungbean seeds (Vigna radiata) from the
attack of Callosobruchus chinensis. The
efficacy of plant extracts were assessed at different doses (10µml, 15µml and
20µml) on the oviposition rate, adults emergence
and longevity of Callosobruchus chinensis. It
was found that the oviposition rate, adults emergence
and longevity of Callosobruchus chinensis on
mungbean seeds were reduced due to treated with garlic, onion, castor and neem seeds extracts. In all plant extracts of
garlic, onion, castor and neem seeds their effectiveness increased with the increase of doses. Among
the four different kinds of plant extracts neem seeds extract showed maximum efficacy in terms of oviposition
rate, number of adult emergence and adult longevity of Callosobruchus
chinensis..
Key words: Plants extract, Callosobruchus chinensis, Vigna radiata, and Oviposition
