Description:
Delphastus is a native, small 1/15th inch, black/ brown beetle in the lady beetle family. During their approx. 30 day life cycle females can lay up to 4 eggs per day.  In order to lay eggs the female must consume at least 100 whitefly eggs a day. Larva and pupa stages take approx. 6 days each. Larvae are cream colored, alligator like insects. Research has found that each beetle can eat up to 10,000 whitefly eggs.

Delphastus work best if your whitefly population is high, while encaria and eretmocerus do better with light to moderate infestations. Delphastus do not enter diapause/ hibernation during the fall and winter, therefore they can be used indoor or outdoors all year long.

Other whitefly predators such as; Encarsia formosa and Eretmocerus eremicus will co-exist with Delphastus beetle and help expedite control.
