Different Biological Aspects of the Predaceous Mite Euseius scutalis (Acari: Gamasida: Phytoseiidae) and the Effects due to Feeding on Three Tetranychid Mite Species in Hail, Saudi Arabia

Biological aspects, thermal requirement, predation rate and life table parameters of the phytoseiid predatory mite Euseius scutalis (A.-H.) fed on nymphs of Tetranychus urticae Koch was determined at four temperature degrees, 15, 20, 25 and 30 °C. The total developmental durations of female was correlated negatively with increasing temperature. Minimum developmental thresholds (T o ) of egg, larva, protonymph, deutonymph, total immature stages and life cycle of E. scutalis female averaged, 4.26, 10.98, 6.90, 1.20, 2.49 and 2.89; respectively. On the other hand E. scutalis female required 208.33 DD to reach adulthood. The net rate of natural increase (r m ) was 0.008, 0.126, 0.166 and 0.193, whereas the finite rate of increase (e rm ) averaged 1.092, 1.134, 1.181 and 1.213 at 15, 20, 25 and 30 o C; respectively.

“…The life table parameters reported for C. negevi in this study at 35 C are close to that provided by Momen et al (2009) C and 35% RH are slightly lower than reported for E. scutalis against the same prey at 25 C and 70% RH (Al-Shammery 2010). Euseius scutalis performed better on O. afrasiaticus than C. negevi, and this could be due to the higher humidity level used.…”

“…Many authors studied the biology of this predator on various kinds of diets, e.g. tetranycid mites, insects and pollens (Meyerdirk and Coudriet, 1986;Bounfour and McMurtry, 1987;Kasap and Sekeroglu, 2004;Osman et al, 2010;Al-Shammery, 2010;Fouly et al, 2013).…”

Euseius scutalis developed and oviposited when provided with egg stage of Parlatoria ziziphi as prey under laboratory conditions of 28 ± 2°C and 70 ± 5% relative humidity (RH). Euseius scutalis was significantly affected by food source but a slight difference was noticed between females and males. The efficiency of the predator increased as it advanced in its development. Egg incubation period of female and male lasted 2.11 days. The life cycle lasted 8.04 and 7.32 days for female and male, respectively. The female lived for a longer period than that of the male, where longevity was 23.3 and 17.11 days for female and male, respectively. The number of prey eggs consumed per individuals was 16.11 and 10.30 eggs for total immature stages. The female predator devoured 43.81 prey eggs during the oviposition period (11.46 days) and deposited 0.91 eggs per day.
