| Abstract | ||
| Predaceous mites play an important role in the biological control of phytophagous mites and insect pests such as thrips and whitefly. Biological parameters of Amblyseius fallacies Garman were tested under two degree of temperature 20 and 30°C and R.H.70±5% feeding on Thrips tabaci at Fac. Agric., Fayoum Univ., Egypt from March till June. The results indicated that the mean of immature periods at 20°C for eggs, larvae, protonymphs and deutonymphs, reached (2.64, 1.14, 1.86 and 2.79 days) and (2.46, 1.07, 1.93 and 3.21 days) for females and males, respectively. At 30°C the mean of these periods for female reached (2.64, 1.00, 1.64 and 3.21 days), while for males reached (2.50, 1.07, 1.29 and 3.43 days), respectively. The adult longevity period averaged at 20°C were 10.29 & 9.29 days, while at 30°C averaged were 8.14 & 6.86 days for female and males, respectively. Through the oviposition period which averaged between 6.43 and 4.71 days the mean of eggs deposited per female reached to 8.86 and 9.29 eggs at 20°C and 30°C, respectively. The total mean of food consumption for immature stages ( protonymphs and deutonymphs) reached to 3.00 and 2.43 preys at 20°C, while reached to 3.43 and 2.71 preys at 30°C for females and males, respectively. The adult stage consumed from 19.89 to 9.14 preys at 20°C and 23.58 to 10.57 preys at 30°C for females and males, respectively. | ||
