Abstract
Abstract: Pulses have been considered as the poor man’s meat which play an important role in food categories that have been extensively used as staple foods to cover basic protein and energy needs throughout the history of humanity. Chickpea, Cicer arietinum (L.) is one of the major pulse crops grown during the rabi season. There are many insect pests causes losses in both field and storage condition. In storage condition, the pulse beetle, Callosobruchus spp. causes major losses among other pests. the pulse beetle not only causing quatitative losses but also cause qualitative losses in nutrition that makes most pulses unfit for marketing as well as human consumption.
The present research was aimed to study the “Evaluation of botanicals against Callosobruchus chinensis in stored chickpea” were conducted under laboratory conditions at Department of Entomology, Post Graduate Institute, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Experiment was conducted with seven different botanicals namely pepper powder @ 3g/kg seed, turmeric powder @ 10g/kg seed, clove powder @ 3g/kg seed, Groundnut oil @ 5ml/kg seed, castor oil @ 5ml/kg seed, soybean oil @ 5ml/kg seed and untreated control.
One hundred gram of seed was taken in each plastic container of 500g capacity from one kilogram treated stored sample to computing the residual toxicity of botanicals and in which 5 pairs of adult beetles were released and stored under ambient condition. observation was recorded daily from 1st to 7th day of release of beetles to compute the per cent mortality, egg lying, adult emergence, per cent seed infestation, percent weight loss, per cent seed germination and seed vigour of seed, 100g seeds of plastic container of 500g capacity were observed in each month and recorded the observations.
Considering all parameters result revealed that castor oil @ 5ml/kg seed, pepper powder @ 3g/kg seed, clove powder @ 3g/kg seed and groundnut oil @ 5ml/kg seeds performed best in respect of per cent mortality up to six months storage period.
The seeds treated with castor oil @ 5ml/kg seed, pepper powder @ 3 g/kg seed, clove powder @ 3g/kg seed, and groundnut oil @ 5 ml/kg seed were most effective in inhibiting the oviposition of beetles.
Treatment castor oil @ 5ml/kg seed, pepper powder @ 3g/kg seed, clove powder @ 3g/kg seed, were found as the best in checking adult emergence, followed by groundnut oil @ 5ml/kg seed, turmeric powder @ 10g/kg seed and soybean oil @ 5ml/kg seed were found best during the six month of storage period.
Overal data indicated that castor oil @ 5ml/kg seed, pepper seed powder @ 3g/kg and clove powder @ 3g/kg seed were found best pulse grain protectants which prevented the insect infestation and weight loss in seed without adversely affecting germination and viability of seed up to six months storage period. While untreated seeds were adversely affected in all respects.
