Uygulama sonrası zararlı salgınlarına karşı koruma için Beauveria bassiana etkinliğinin depolanmış ürünler üzerinde kalıcılığı

This study was carried out to determine the post-treatment efficacy of three local Beauveria bassiana isolates by applying them against adults common stored-product pests, Sitophilus oryzae L. (Coleoptera: Curculionidae) Rhyzopertha dominica F. (Col.: Bostrichidae) and Oryzaephilus surinamensis Silvanidae). 
 For biological tests, wheat grains were mixed with fungal spores at 1000 ppm (w/w) concentration, then 20 release 1, 15 28 days after treatments. The tests S. oryzae; mortality rate initially 33.3-41.6% 68.3-76.6%; declined 6.6-18.3% 13.3-21.6% on 7th 14th day, respectively, when released later. initial R. 46.6-50.0% 93.3-95.0%; became 10.0-18.3% 16.6-28.3% day 41.6-46.6% 70.0-85.0%, decreased 8.3-15.0% 13.3-20.0%, Mortality rates end each incubation period, for all testing insect species, significantly reduced waiting time prolonged. periods, similar obtained from efficiacy loss observed. All results together indicate that responsible factors time-dependent activity in B. should be determined line these data precautions need taken.
