Laboratuvar koşullarında Perillus bioculatus (F.) (Hemiptera: Pentatomidae)' un gelişme süresi ve ölüm oranı üzerinde ön çalışmalar

Abstract

Abstract: The study was conducted to investigate the development of Perillus bioculatus (F.) (Hemiptera: Pentatomidae), a predator of the Colorado potato beetle, Leptinotarsadecemlineata (Say.) (Coleoptera: Chrysomelidae), at two different temperatures. Theincubation periods were 5.94 and 4.94 days, and hatching rates were 94% and 95%,respectively, at 26±1 o C and 29±1 o C. The total nymphal period was 15.57 days at 26±1 o Cand 15.13 days at 29±1 o C . Gender proportions were calculated as 0.75 and 0.60 (F/M) at26±1 o C and 29±1 o C, respectively. The mortality rate was high at both temperatures.
