Assessment of temperature effects on the development and fecundity of Pullus mediterraneus (Col., Coccinellidae) and consumption of Saissetia oleae eggs (Hom., Coccoida)

摘要: Eggs, larval and nymphal periods fecundity of Pullus mediterraneus were examined under 16 h light : 8 h dark combined with six constant temperatures: 15, 20, 25, 30, 35 40°C. Eggs Saissetia oleae used as prey. The developmental time at 30 35°C was 17.23, 4.5, 2.64, 1.67, 1.28 days for eggs 98.47, 68.88, 53.94, 28.96, 36.51 days larval–pupal duration, respectively. At 7°C no hatched, 40°C all the stages died after 36 h maximum exposure except three last stages. females rearing different temperatures ranged between 1.7 15°C 601.86 30°C. pre-oviposition period 23.75 days 3.47 days 35°C. consumption S. by larvae reached 597.69 during pre-imaginal development. Females attacked more than males averaging 77.69 ± 22.34 eggs per 4 day compared 46.97 ± 10.12 eggs males.
