Losses (5–71%) were highest in the sites with the smallest rice area in which pests were concentrated and the poorest soils (which constrain yield compensation) along a continuum of dryland rice habitats. Karnataka and Himachal Pradesh, up to 100% losses in storage have been reported. Tubers are heavily damaged in the, Phthorimaea operculella occurs in almost all potato-producing states in India and is considered to be a major potato pest in several states. wer third of the plant on the underside of leaves. Damage caused by lygus bug feeding may be serious, and there are efforts underway to determine the consequences of any such damage on potato yield.

After two months of storage, there was no potato tuber moth infestation in tubers treated with CIPC (0.06%) as compared to 84% in control. These pests can damage the plants by feeding on leaves, reducing photosynthetic area and efficiency by attacking stems, weakening plants and inhibiting nutrient transport, and by attacking potato tubers destined for consumption or use as seed. 17 0 obj Both the adult striped beetle and the black-spotted, hump-backed red larvae are foliage feeders.

It takes up to 36 days for them to develop from eggs to adult insects. With larvae already in tubers, the CIPC was extremely effective, with a success rate of 100%. In storage, dry leaves of Eucalyptus, Lantana, Ageratum, Eupatorium, soapnut, and wheat straw offer significant reduction in infestation. There was 100.0% mortality of adults released on CIPC (0.06%) treated tubers in glass jars. endstream This book presents a complete review of the scientific literature from the considerable research effort over the last 15 years, providing the necessary background information to the subject of studying the biology management of insect pests of potatoes, assessment of recent scientific advances, and a list of further readings. and facilitate the transition of the potato industry toward more sus-tainable IPM practices.
