SCREENING OF ELITE BREAD WHEAT GERMPLASM AGAINST SHOOT <i>FLY ATHERIGONA APPROXIMATA</i> MALLOCH

Abstract

Shoot flies (Diptera: Muscidae) of Atherigona spp. are the major insect pests in several cereals and millets causing significant yield loss. Usually, bread wheat (Triticum aestivum L.) is less attacked by insect pest, however under changed climate-pest scenario, shoot fly has become a major insect pest. Present study observed the shoot fly Atherigona approximata Malloch as major species under wheat ecosystem. Among the 30 wheat genotypes screened, none of them were found to be highly resistant except for two advanced ones, UAS BW-12417 and UAS BW-11110 found resistant (3.13 and 5.00% deadheart). By this screening, 16 entries are categorised as moderately resistant, eight are grouped under susceptible and four genotypes are classified as highly susceptible.
