Extract

In 1925 a brief generalised account was given of the biology of Sacadodes pyralis, Dyar, a Noctuiid moth that appeared likely to prove to be a serious pest of cotton, should the cultivation of this crop be taken up on a large scale in Trinidad. Previously little attention appears to have been paid to the potential danger, which the writer considers to be very real.

Sacadodes is not only very closely allied to Diparopsis castanea, Hampson, the Sudan bollworm, but it is also remarkably similar to that insect both in the general facies of all stages (Plates xxi and xxii) and in its bionomics.
