Gravena, S., Leão Neto, L.R., Moretti, F.C., & Tozatti, G. 1988 [Efficacy of insecticides on Selenaspidus articulatus (Morgan) (Homoptera, Diaspididae) and effect on natural enemies in citrus crop].. Científica (Jaboticabal) 16(2): 209-218.

Notes: Several insecticides were evaluated in order to study the action against the rufous scale Selenaspidus articulatus (Morgan) and their effects upon the beneficial arthropods in a citrus grove. Dimethoate was the only effective chemical, by the experimental conditions at 0.025 kg IA/100 l, perhaps causing severe injuries to the beneficials enemies. The most common species of the arthropod predators were in the coccinellids Azya luteipes (Muls.), Pentilia egena (Muls.), Coccidophilus citricola (Brethes), Cryptognatha sp., Calloeneis sp. and the chrysopid Chrysopa sp. The most selective insecticides were mineral oil, aldicarb and abamectin. The parasitism was low: 3.1%. The main control agent of roufous scale was the fungus Aschersonia aleyrodis associated with another of the Dematiaceae family.
