Large scale demonstrations of biological control based integrated pest management (BIPM) practices were carried out in the 'kole' lands of Koorkkencherry Panchayath of Thrissur district in Kerala and compared with conventional farming. Trichogramma japonicum was released against rice stem borer and leaf folder @ 1 lakh ha−1. The results showed that dead heart and white ear head incidences were on par in the two systems of cultivation. In the case of leaf folder significantly lower incidence was observed in BIPM. There was no significant difference in grain yield. The population of predators like coccinellids and spiders were significantly higher in BIPM.Keywords

A stem gall fly, Cecidochares connexa (Macquart) was released in 2007 and 2008 at Kerala Agricultural University Campus for the biological control of Chromolaena odorata (L.) King and Robinson and the releases made during 2008 resulted in its establishment. There ws a significant reduction in plant height on the galled plants at 30 and 60 days after gall formation. The gall fly could spread up to 500m, 100m, 50m and 100m from release points towards north, south, east and west, respectively. The gall fly could successfully overcome the dry season from January to May at Thrissur.Keywords

Papaya mealybug, Paracoccus marginatus Williams and Granara de Willlink (Hemiptera: Pseudococcidae) was first observed in Kerala during 2009. It was found infesting on papaya, mulberry, brinjal, tomato, cowpea, jack, plumeria, hibiscus, ocimum, raulfia, teak and rubber. Acerophagus papayae Noyes and Schauff (Hymenoptera: Encyrtidae) was mass reared and released @ 25-100 nos. / plant in Thrissur and Ernakulam districts of Kerala. Before the release of the parasitoid the incidence was above 60 per cent and intensity was medium to very high. A rapid survey carried out in the released areas showed that the percentage of infestation came down to below five and intensity of infestation was medium to very low. In other districts the incidence was low with the activity of A. papayae.Keywords

Many entomophagous insects attack the black-headed caterpillar of coconut, Opisina arenosella Walker during its developmental stages. Goniozus nephantidis (Muesebeck) is a gregarious larval parasitoid of O. arenosella. During summer months of 2003-04 and 2004-05 the parasitoid was evaluated in the field in Kerala by following two methods - trunk and crown release that were compared with control. There was significant reduction in the population of O. arenosella after third to sixth releases in treated palms, when compared to control palms. There was no significant difference between the two methods of release of G. nephantidis in reducing the population of O. arenosella. Hence farmers could easily and effectively adopt the trunk release method.Keywords

Blackheaded caterpillar, Opisina arenosella Walker is a major pest of coconut in India. Cardiastethus exiguus Poppius is a potential predator of eggs and newly hatched larvae of O. arenosella. Field release and evaluation of C. exiguus was carried out during summer months of 2003–04 and 2004–05 in two pest-infested areas of Kerala, The release rates were 50 and 100 nymphs/adults per tree in the crown region. Totally three releases were made. There was significant reduction in the population of O.arenosella after release of the predator. The two release rates (50 and 100 nos./tree) were found equally effective in reducing the population of O. arenosella.Keywords
