Suturaspis pistaciae (Lindinger) Hemiptera: Sternorrhyncha: Coccoidea: Diaspididae) is an important pest on pistachio trees of Turkey. Various observations on the biology of Suturaspis pistaciae were carried out under laboratory conditions. In this study, development time of immature stages of one of most important pest of pistachio Suturaspis pistaciae were studied at 27 ± 1°C and 65% ± 5 Rh. with 16/8 hours lighting period under laboratory conditions. Development time of immature stages of S. pistaciae determined first larvae stage: mean 16 (10-28) days, second larva stage mean 12.9 (7-15) days and virgin female stage 8.5 (4-12) days shortened when biological stages increase. Development time from active larva to adult was 37.4 days. The death rate from larvae to adult until it becomes 50% is determined. Stereoscopic binocular Microscope with different biological periods of the pests was measured. Biological measurements are made for a biological stage of 25 individuals each. In addition, morphological characteristics of each stage were also investigated.
