Abstract
the present work was conducted to study the effect of temperature on development, fecundity and food consumpution of Amblyseius cydnodactylon (Shehata & Zaher) under laboratory conditions. The biology of A. cydnodactylon may be a considerable value for controlling P. tritici in Egypt. The results showed that the developmental period increased with temperature decrease. Fecundity, longevity and lifespan were longer at 25°C and lower at 35°C. At 25°C developmental period was short with higher fecundity and maximum longevity, where as it was the most suitable temperature for development of A. cydnodactylon , while 35°C was the least suitable.The results on food consumption showed a significant effect of temperature on developmental stages of A. cydnodactylon . The larvae of this predator did not feed during the experiment, and predation activity started just after the mites entered the protonymphal downloaded stage. Feeding capacities of protonymph and deutonymphal stages were in a similar trend. These were increased with increasing temperature from 20◦C to 25◦C, and then decreased at 30◦C and finally, increased again at 35◦C. The highest means for total prey consumption of females were recorded during oviposition, when they devoured an average of 103.0, 189.3, 109.0 and 79.0 prey at 20, 25, 30, and 35◦C, respectively. The highest and lowest values of the mean preyprey) and 20◦C (2.1 prey), respectively. During adulthood, the highest number of prey consumed was at 25◦C (201.9 prey), which decreased to 116.6, 110.8 and 86.9 individuals at 30, 20 and 35◦C، respectively. consumption by postoviposited females was observed at 25◦C (6.4
