Abstract
In India, agriculture is a major occupation for people, where the bulk
of crops are cultivated, stored and consumed. During storage, various biotic
and abiotic factors affect the quality of grains. Among biotic factors, maximum
damage to the store grains is caused by insect pests of family bruchidae. Among
all the genera of this family, members of genus Callosobruchus are the
major pests of stored grain as they cause extensive damage to the grains and
hence are responsible for great economic loss to farmers. C. analis is
one of major pest, which exclusively attack seeds of family Leguminosae in
stores. For the control of these pest populations, lots of chemical pesticides
are being used but these are not safe for consumption as it causes serious
health hazards to consumers, therefore, during past few years, the focus has
been shifted towards the use of botanicals for the control of these
store-bruchids. Hence, laboratory experiments were conducted to assess the
efficacy of four plants oil namely, Cocos, Nigella, Eucalyptus and Syzygyium
against C. analis infesting stored Vigna radiata. The test
plant oils were applied at four levels of concentrations (0.2, 0.6, 0.8 and
1.0mL/100g seed) and control in which no test plant oil was applied. The
studies reveal that these plant oils show significant level of adult mortality,
reduced oviposition by female adult C. analis, and reduced F1 progeny
emergence from infested V. radiata.
