Bioactive Chemical Compounds Identified in Methanolic Extract of Trogoderma granarium

[...]it has been described as one of the 100 worst invasive species worldwide 4-9 Trogoderma granarium is a serious pest of stored products under hot dry conditions. Because of its refuge seeking behavior, it is extremely difficult to eradicate this insect from premises or transport facilities, and the existence of a special type of recurrent dormancy in the larval stage enables populations to exploit times of food abundance and to survive long periods of deprivation 20-25. According to FAO estimate, 10 to 25% of the world harvested food is destroyed annually due to insects and rodent pests. Chemical insecticides such as malathian, cypermethrin, bifenthrin are used for rapid control, but are expensive, not readily available and may be poisonous to humans and environment. [...]malathian and cypermethrin have gone ineffective due to development of resistance in insect pests of stored grain, particularly in Trogoderma granarium 73-83.
