Abstract
In the laboratory experiments, adult stage of the confused flour beetles Tribolium confusum was exposed to treated Petri dishes with three conventional insecticides (malathion, pirimiphos - methyl and cyhalothrin) and one biocide (abamectin) separately. Pirimiphos-methyl proved to be the most potent of the three synthetic insecticides, followed by cyhalothrin then malathion. The biocide abamectin comes after malathion, but its potency was obvious. Also, the relative toxicity of some monoterpenoids and three essential oils to T. confusum adults was assessed using contact and fumigation techniques. Cinnamic aldehyde was the most effective followed by trans anithole, cinnamic alcohol and menthol, while pulegone and a-terpineol were the least toxic compounds when compared using the residual film method. Again, in the fumigation assay, cinnamic aldehyde proved to be the most toxic compound with LC50 value 11 mg / L air / 48 hours followed by rosemary oil, while menthol was the least effective fumigant. In addition, the results indicated that heat treatment up to 60 °C for 1 hour will get rid of T. confusum and exposure to the microwave radiation for 25 sec was successful in causing 100% mortality of the confused flour beetles. Combinations of these methods are suggested as new alternatives within the IPM program to combat the infestation of various insect pests.
