life table of the sugarcane mite oligonychus sacchari mcgregor (acari: tetranychidae) under laboratory conditions
sugarcane mite, oligonychus sacchari mcgregor, is one of the most important pests of sugarcane plant in khuzestan province, southwest of iran. during a two-year study (2007-2008), the biology of the sugarcane mite, o. sacchari, was investigated on three commercial varieties cp48-103, cp57-614 and cp69-1062 under laboratory conditions (temperature 30±1° c, rh% 60±5 and a photoperiod of 16:8 (l:d...
متن کاملComparison of the susceptibility of several cultivars of avocado to the persea mite, Oligonychus perseae (Acari: Tetranychidae)
We compared the susceptibility of seven cultivars of avocado, Persea americana, to feeding by Oligonychus perseae. Based on the percentage of leaf area damaged by mites in February 1998, cultivars were categorized into three groups: Hass and Gwen were `susceptible', Fuerte, Lamb Hass and Reed were `resistant', Esther, and Pinkerton were of `intermediate' susceptibility. A life table study in th...
