| Description |
Epilachna vigintioctopunctata, Family: Coccinellidae 7mm ladybird on Solanum nigrum Henosepilachna vigintioctopunctata is a species of beetle in the family Coccinellidae. It is commonly known as the 28-spotted potato ladybird or the Hadda beetle. It feeds on the foliage of potatoes and other solanaceous crops. It originated in the far east of Russia. It was previously called Epilachna vigintioctopunctata and is a cryptic species complex. This species causes damage to agricultural crops in the three families Solanaceae (potato, tomato, aubergine and pepper), Cucurbitaceae (cucumber, melon, water-melon and pumpkin) and Fabaceae (soya and haricot beans). However the optimal host plant for the reproduction of over-wintered beetles and the development of their larvae is the potato. The loss in yield of potato tubers may reach 25% in heavy infestations. Control is by the use of resistant varieties of plants, crop rotation, the growing of solanaceous crops in open windy locations, the destruction of all plant residues and the use of pesticides when necessary ______________________________ In India, biological control by native natural enemies was not efficient enough to be practical according to Lall (1964). However, in a review of the biology and control of the species in India, Rajagopal and Trivedi (1989) mentioned various natural insect control agents and two disease-causing organisms (Aspergillus flavus and Bacillus thuringiensis) which were sometimes able to control populations. |
