Abstract

Association of nine coccinellid beetles with Poplar (Populus deltoides) was recorded first - time from Poplar nurseries, in Tarai region of Uttaranchal and Haryana. These include eight predacious species viz. Anegleis cardoni (Weise), Coccinella septempunctata Linnaeus, Hippodamia variegata (Goeze), Illeis cincta (Fabricius), Menochilus sexmaculatus (Fabricius), Micraspis discolor (Fabricius), Propylea japonica (Thunberg) and Rodolia fumida Mulsant found feeding on aphids and other small insect preys infesting on Poplar foliage. Another coccinellis, Epilachna vigintioctopunctata (Fabricius) was found to be a phytophagous species feeding on Poplar foliage. A key for easy identification of the recorded species has been incorporated.

Abstract

The deffotiation epidemic in ailanthus excelsa roxb in satyanarain research nursery was studies. The insect responsible for epidemic was philosamia cythia drury. This is a polyphagous pest and reported for the first time as deffolator of ailanthus excelsa Egg, larva, pups and adult of the species are described and notes on their biology are given. A fungal pathogen, beauveria basslana(Balsama) Vulliemin has been recorded killing the larvae of P.cynthia in the field. The pathogen appears to be a promising organism for microbial control of Ailanthus deffolator in the field.

Abstract

Epidemic defoliation of deodar forests by Ectropis deodarae in Lolab Valley was reported in August, 1982. The population of the pest was monitored in early spring of 1983, by counting pupae on the ground per unit area, the ascending female moth stuck up on sticky bands applied to deodar trees and also larval population per twig. As the population was found to be on the increase and an epidemic was threatened a decision was taken to spray an organophosphorous compound fenitrothion from the air. Two Beaver aircrafts were used for the operation. The dispensing equipment used was boom and nozzle and the insecticide dosage was 1 litre per hectare Pre and Post-treatment counts of the pest population gave 92% kill. Non-target organisms hit by the spray were also monitored. There was no mortality of birds and other vertebrates. A good number of non-target insects including Calosoma beesoni, the predator beetle of Ectropis deodarae were also hit. The dosage can be safely reduced to 775 ml/hectare which will effectively kill tbe pest and cause less harm to predators.
