Preliminary observations on the bionomics of potato tuber moth (Gnorimoschema oper-culella Zell.) and its control in Binar, India.
The moths are not carried over to the next crop in the seed tubers; they fly out from potato stores in September and settle on brinjal and tomato plants before transferring to the new potato crop. Thirteen broods were noted within a year, eight in store and five in the field. Control was effected by dipping the potatoes in 5 % phenyl solution for 15 minutes, by using a covering material of sand and garlic bits, and by hanging a paraffin oil trap in the store. Potatoes harvested before mid-February are not infested. C.W.S.H.
