Özet

Temperature has significant effects on the development, survival, and reproduction of ectothermic organisms. In this study, we examined the effect of temperature on the demographic characteristics of two predatory mite species, Neosciulus womersleyi (Schicha) and N. longispinosus (Evans), reared on Tetranychus urticae Koch. The developmental and reproductive traits of both species were examined at 10 constant temperatures between 15 C and 37.5 C. The preadult development time of N. womersleyi and N. longispinosus decreased with increasing temperature until 32.5 C and 35 C, respectively. The lower developmental threshold (T0) and thermal constant (K) estimated by using a linear model were 11.61 C and 69.36 DD for N. womersleyi and 11.92 C and 61.5 DD for N. longispinosus, respectively. Total preoviposition period and total longevity of females and males of N. womersleyi and N. longispinosus decreased with increasing temperature. The mean generation time (T) first decreased with temperature until 32.5 and 35 C for N. womersleyi and N. longispinosus, respectively, and then increased at higher temperatures. The R0 and r values first increased with temperature until 32.5 and 30 C for N. womersleyi and N. longispinosus, respectively, and then decreased at higher temperatures. The R0 and r values for N. longispinosus at 37.5 C were 0.3 offspring and 0.143 d1, respectively. These results show that N. longispinosus is less fit than N. womersleyi at 37.5 C. © The Authors 2017.
