Abstract
The efficacy of three different edible oils of mustard, soybean and coconut for the control of Callosobruchus chinensis was assessed on the basis of the rate of oviposition, adult emergence and longevity. It was found that the eggs deposited by Callosobruchus chinensis on mungbean seeds was significantly lower (at α=0.05) on the treated pulses than their respective control. The number of eggs, adults emerged and longevity of Callosobruchus chinensis on mung pulses treated with mustard, coconut and soybean (10, 15 and 20 µml) were lowered than their respective control pulses. The rate of oviposition was lowered along with the increases of the doses of oil. When the pulses were treated with different doses of the edible oils, mustard oil showed the lowest number of eggs, adult emergence and longevity. In case of soybean and coconut oils adult emergence and longevity was zero at the dose of 20 µml. Among the three edible oils coconut oil was more effective.
Key words: Edible oils, Callosobruchus chinensis, Phaseolus aureus, Oviposition, Adult Emergence, Longevity.
