The majority of resistance studies to insects in soybean, Glycine max (L.) Merr., has stemmed from a discovery of three cultivars resistant to Mexican bean beetle (Epilachna
varivestis Mulsant) (PI 171451, 229358, and 227687) (Van Duyn et al., 1971, 1972; Khush and Brar, 1991).

Use of trap crops like mint, African marigoldBeetles, especially, the epilachna
beetle, can cause damage to young plants but older ones can tolerate leaf damage.
However, toxic effects were observed for larvae and adults of Epilachna

Besides its importance as a vegetable in daily life it is also subjected to attack by a number of insect pests like shoot and fruit borer, Leucinodes orbonalis (Guenee.), whitefly, Bemisia tabaci (Gennadius), jassid, Amrasca biguttula biguttula (Ishida), aphid, Aphis gossipy (Glover); Mexican bean beetle, Epilachna
varivestis (Mulsan), red spider mite, Tetranychus urticae (Koch) and some non-insect pests .
