| Abstract | ||||
| This work aimed to study different biological aspects of the predatory mite, Pulaeus martini (Den Heyer) when fed on different diets mainly free living nematode, Rhabditella muscicola Chitwood and two different fungi (Fusarium oxysporum Schlechtendahl and Pythium spinosum Sawada at 20, 25, 30 and 35 + 2 °C and relative humidity 75+5% R.H. in laboratory. Obtained data indicated that the different biological aspects of P. martini was significantly affected by different mentioned diets and temperatures. The male lasted shorter time than female in different periods. The life periods of individuals increased as well as temperature increased from 20 up to 35 ºC. The lowest period of life cycle recorded when the male fed on free living nematode (10.89 days) at 35 ºC, while it elongate to (23.89 days) was male reared on F. oxysporum at 20 ºC. Female longevity recorded the longest period when it fed on F. oxysporum at 20 ºC (37.21 days) while the shortest longevity period recorder at 35 ºC. (12.16 days). On the other hand the free living nematode elongated the life span time for predatory mite females at 20 ºC it lasted 62.48 days, but the shortest time was recorded when female individuals fed on F. oxysporum at 35 ºC (37.89 days). From the obtained results also, it was noticed that the best diet for rearing the cunaxid mite P. martini was F. oxysporum at 25 ºC where it recorded the highest number of deposited eggs (73.79) but the least favorable one for feeding was the fungus P. spinosum at 35 ºC (48.71 eggs). | ||||
