Seasonal phenology and natural enemies of Maconellicoccus hirsutus (Hemiptera: Pseudococcidae) in Australia
Florida Entomologist 85 (3), 494-498
Abstract: Foreign exploration for natural enemies of pink hibiscus mealybug, Maconellicoccus hirsutus, was conducted in Australia from 2000 to 2002. In Queensland, the predaceous beetle Cryptolaemus montrouzieri, the predaceous drosophilid fly, Cacoxenus perspicax and the encrytid parasitoid Gyranusoidea indica were recovered. In Western Australia and the Northern Territory a predatory noctuid, Mataeomera sp., an aphelinid parasitoid Coccophagus sp., and a probable encyrtid hyperparasitoid, Coccidoctonus sp. were reared from M. hirsutus on a native Hibiscus species. A field study was conducted from February 2000 to March 2002 in Sherwood, Queensland to document the seasonal phenology of M. hirsutus in its native habitat on its preferred host, Hibiscus rosa-sinensis. Populations of the mealybug stayed at or below detectable levels for most of the study with minor population peaks in the summer months.
Se llevo a cabo una exploración exótica de enemigos naturales del la cochinilla harinosa rosada de hibisco, Maconellicoccus hirsutus, en Australia de 2000 a 2002. En Queensland, se recubrieron el escarabajo depredador, Cryptolaemus montrouzieri, la mosca drosofílida depredador, Cacoxenus perspicax y el parasitoide encírtido Gyranusoidea indica. En Australia Occidental y en el Territorio del Norte, un noctuido depredador, Mataeomera sp., un parasitoide afelínido, Coccophagus sp., un encírtido, Coccidoctonus sp. lo cual es probablemente un hiperparasitoide, fueron criados de M. hirsutus sobre una especie nativa de Hibiscus. Se llevo a cabo un estudio del campo en febrero 2000 a marzo 2002 en Sherwood, Queensland para documentar la fenología estacional de M. hirsutus en su hábitat nativa sobre su hospedero preferido, Hibiscus rosa-sinensis. Poblaciones de la cochinilla harinosa se mantenia al nivel de o debajo del nivel detectable para la mayor parte del estudio con cumbres menores de población en los meses de verano.
