Efficacy of new isolates of the entomopathogenic fungus (EPF), Clonostachys rosea, against adult stage of the most serious coleopteran stored product insect pests in Iraq, Trogoderma granarium Everts (Coleoptera: Dermestidae), Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) and Callosobruchus maculatus Fabricius (Coleoptera: Chrysomelidae), was evaluated under laboratory conditions. Two isolates of C. rosea, associated with the green peach aphid (Myzus persicae Sulz.), were isolated and investigated. Efficacy of C. rosea isolates was evaluated by two concentrations (1 × 108 and 1 × 106 conidia ml−1). Corrected mortality rates caused by both C. rosea isolates, 6 days post-treatment, with 1 × 108 conidia ml−1, ranged from 70.7 to 75.7%. Fungal infection caused 37–53% reduction in total fecundity of the adult females of the three tested insect species, 6 days post-treatment. Obtained results demonstrated that C. rosea isolates had potentials as a biological control agent against coleopteran stored product insect pests. However, further studies under commercial storage conditions are required.

玫瑰色梭菌（Clonostachys rosea）作为一种有前途的致病真菌，在实验室条件下对鞘翅目贮藏产品害虫的功效

昆虫病原真菌（EPF）新分离株对伊拉克最严重的鞘翅目储藏产品害虫的成虫期，破草皮草（Etrogoderma granarium Everts（鞘翅目：Dermestidae），Tri藜Tribolium castaneum Herbst（Coleoptera：Tenebrionidae）和Call属）的功效在实验室条件下评估了Fabricius（鞘翅目：金眼科）。分离并研究了与绿色桃蚜（Myzus persicae Sulz。）相关的玫瑰色念珠菌的两个分离株。通过两种浓度（1×108和1×106分生孢子ml-1）评估玫瑰色念珠菌分离物的功效。治疗后6天，由两个玫瑰花分离株引起的校正后死亡率为1×108分生孢子ml-1，范围为70.7至75.7％。真菌感染在治疗后6天导致三种测试昆虫物种的成年雌性的总繁殖力降低了37–53％。获得的结果表明，玫瑰色念珠菌分离物有潜力作为对抗鞘翅目贮藏产品害虫的生物防治剂。但是，需要在商业存储条件下进行进一步研究。
