Abstract

The present study was conducted to evaluate the population densities of the mites associated with tomato hybrids and its relation with the prevailing temperature at Demo district, Fayoum Governorate, Egypt during two summer growing seasons (2017& 2018). Four mite species were found, two species were considered as phytophagous mites Tetranychus urticae Koch and Aculops lycopersici Massee, the 3rd as heterogeneous Tydeus californicus Banks and the 4th as predacious mite Amblyseius cydnodactylon Shehata & Zaher. Population densities were evaluated on three tomato hybrids, namely, Supper-gekal, 09 and El-basha. T. urticae only was collected during 2017 season and showed its peaks in the second week of June, first week of June, third week of May for super-Jekal, 09 and El-basha, respectively, while during 2018 season, A. lycopersici, T. californicus and A. cydnodactylon were collected, A. lycopersici peaked once during the season in first, fourth weeks of August and first week of September for super-Jekal, 09 and El-basha, respectively. Biological aspects of A. lycopersici on tomato hybrid (010) at 20°C and 60% R.H were studied. The periods of protolarvae and duetolarvae were recorded (1.42 and 2.5 days) and (1.28 and 2.14 days) for females and males, respectively. Longevity of females was averaged 4.78 days. The fecundity was recorded 1.6 eggs/female with 93% egg hatchability and the egg incubation period was 1.28 days.
