Life history of Sancassania polyphyllae (Acari: Acaridae) feeding on dissected tissues of its phoretic host, Polyphylla fullo (Coleoptera: Scarabaeidae): temperature effects
Experimental and Applied Acarology 53 (1), 41-49
Abstract: The effect of temperature on the development and fecundity of Sancassania polyphyllae fed on tissues of Polyphylla fullo larvae was studied at 15, 20, 25, 30, and 35 ± 1°C and 65 ± 10% RH in a dark incubator. Mean developmental period of immature stages decreased significantly with increasing temperatures from 15 to 30°C. Developmental periods at 30-35°C were not significantly different. The estimated lower developmental thresholds of the various immature stages ranged between 10.1 and 11.5°C. The thermal constant for the egg-to-female adult was 93.5 degree-days. The pre-oviposition, oviposition, and post-oviposition periods and female longevity were significantly longer at 15°C than at higher temperatures. Mean total and daily fecundity were the highest at 25°C, which were significantly different from those obtained at 15, 20 and 30°C. The net reproductive rate (R 0) was the highest at 25°C (588.3 female/female). The longest mean generation time (T 0) occurred at 15°C (36 days) and the shortest occurred at 30°C (9.2 days). The highest intrinsic rate of increase (r m) for S. polyphyllae was observed at 25 (0.61 female/female/day) and 30°C (0.62 female/female/day).
