Abstract

The biology of Agistemus exsertus Gonzalez was studied to determine the suitability of different phytoseiid eggs as prey. The development was faster and reproduction was higher when A. exsertus fed on eggs of Amblyseius lindquisti Schuster and Pritchard, Neoseiulus cucumeris (Oudemans) and Amblyseius zaheri Yousef and El borolossy (6.57 days and 111.5 eggs; 6.71 days and 110.1 eggs and 6.93 days and 101.0 eggs) than that of Euseius scutalis Athias-Henriot, Neoseiulus barkeri (Hughes) and Amblyseius swiriskii Athias-Henriot (8.6 days and 63.1 eggs; 7.29 days and 52.0 eggs and 7.87 days and 37.7 eggs), respectively. A. exsertus consumed daily more N. barkeri and A. zaheri eggs (4.63 and 3.85) than other phytoseiid eggs, respectively. Deits of A. lindquisti, N. cucumeris and E. scutalis (eggs) provided the greatest female longevity and the least was in case of N. barkeri.
