| Abstract: | The entomophagous nematode Hexamermis sp. was recorded for the first parasitizing larvae of top shoot borer Cydia hemidoxa Meyr. On black pepper Piper nigrum L. at Peruvannamuzhi (Calicut District, Kerala State) in India. The incidence of parasitism was observed in the field during June to November and was high during July and August; up to 76.7 % of larvae were parasitized during August 1991. A highly significant and positive correlation was observed between incidence of parasitism and rainfall. Hexamermis sp. appears to play an important role in the natural control of C.hemidoxa on black pepper |
