Pediobius foveolatus (Crawford) (Fig. 1 and 3), is a tiny exotic parasitoid wasp that is used for biological control of Mexican bean beetle, Epilachna varivestis (Fig. 2), an important insect pest of snap beans, lima beans, and sometimes soybeans mainly found at economic levels in the eastern United States. Pediobius foveolatus is in the family Eulophidae, and is the most successful biological control agent for Mexican bean beetle. This wasp only attacks beetle larvae, not eggs or adults. It is commonly used by smaller, organic growers; but is also mass released throughout the state of New Jersey, by their state department of agriculture.
