Extract

Ephialtes brevicornis (Grav.) has been found to parasitise the prepupal stage of Plutella maculipennis (Curt.) under laboratory conditions.

A general description of the life-cycle of E. brevicornis on P. maculipennis is given and it is found to occupy 16 days from egg to adult at 20°C. and a R.H. of 60 per cent. Comparative descriptions are given of the five larval instars. The egg is also described.
