Feeding injury to 'Robinson' tangerine leaves by Brevipalpus mites (Acari: Tenuipalpidae) in Florida and evaluation of chemical control on citrus
Florida Entomologist 77 (2), 265-271
Abstract: Larvae, nymphs and adults of the false spider mites Brevipalpus phoenicis (Geijskes) and B. obovatus Donnadieu (Acari: Tenuipalpidae) were found feeding on the ventral surface along the midrib of 'Robinson' tangerine leaves during December 1990. Resinous irregular areas were present in association with the chlorotic midvein areas of injured cells on the lower leaf surface. Similar injury was occasionally evident on some lateral veins in association with the mites. Yellowed, blistered areas were evident on the upper leaf surface opposite the injured areas on the lower leaf. Leaf drop was evident only on trees that were heavily infested with false spider mites. This type of leaf injury by Brevipalpus mites has not been previously reported on Florida citrus. Chemical control evaluations showed that AC 303,630 in combination with petroleum oil, pyridaben, fenbutatin-oxide, dicofol or high rates of sulfur provided at least 35 days control. Ethion was less effective and carbaryl failed to control these mites.
