The results showed the overwintering-generation Chilo suppressalis prefers to spawn on verdant rice leaf blades (face, upper part). The investigation on spawning habit of Chilo suppressalis would provide a theoretical basis for the fore-casting and control of Chilo suppressalis.展开更多

C. asparagi (common asparagus beetle) is an important pest of Asparagus officinalis L. crops in Turkey and the world. Therefore, determining of the protist pathogens of C. asparagi is aimed. During the study, a total of 1,099 C. asparagi adults were examined thoroughly using a light microscope. Insects were collected from the provinces of Manisa, Eskisehir and Bahkesir in Turkey, with 117 of them collected from Manisa, 204 of them from Bahkesir and 778 of them from Eskisehir. A neogregarine pathogen was found in Bahkesir and Manisa. Total infection rate was 18% for Bahkesir between the years 2014-2015 and 15.3% for Manisa in 2011. Oocysts of the neogregarine pathogen were observed only in malpighian tubes of C. asparagi adults. Fresh mature oocysts of the neogregarine was measured as 9.34 ± 0.74 lam (n = 50) in length and 5.27 ± 0.36 μm (n = 50) in width. Identification of entomopathogens is prerequisite for their use in biological control.展开更多
