Özet
Anthocoris minki Dohrn is a promising indigenous Anthocoris species for the biological control of Agonoscena pistaciae Burck. and Laut. (Homoptera: Psyllidae) in pistachio orchards in Turkey. The adult longevity, fecundity, life table parameters and prey consumption of A. minki fed on Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs were studied at combinations of three constant temperatures (20, 25 and 30 +/- A 1A degrees C) with two relative humidity (RH) levels (40 and 65 +/- A 5%). Studies indicated that temperature and RH significantly affected adult longevity, fecundity and prey consumption of A. minki. The greatest adult female longevity was 116.0 days at 20A degrees C and 65% RH; the shortest adult female longevity was 27.5 days at 30A degrees C and 40% RH. At all tested temperatures, the oviposition period and prey consumption of both females and males significantly decreased at low RH compared to high RH. The highest and lowest total fecundities were 276.0 eggs (at 20A degrees C and 65% RH) and 42.4 eggs (at 25A degrees C and 40% RH), respectively. The intrinsic rates of natural increase (r (m)) at 40 and 65% RH were 0.049 and 0.076 at 20A degrees C, 0.072 and 0.096 at 25A degrees C and 0.076 and 0.112 at 30A degrees C, respectively. The highest mean numbers of E. kuehniella eggs consumed by females and males were 859.6 (at 20A degrees C) and 515.3 (at 25A degrees C) at 65% RH, respectively; the lowest were 183.3 (at 20A degrees C) and 95.5 (at 25A degrees C) at 40% RH, respectively.
