Abstract
The pink hibiscus mealybug (PHM), Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) and the associated hymenopterous parasitoid, Anagyrus kamali Moursi, 1948 (Hymenoptera: Encyrtidae), are reported for the first time in Brazil. Specimens of the PHM were collected on nine hosts plants, Annona muricata L. (Anonnaceae), Glycine max (L.) Merr. (Fabaceae), Centrolobium paraensis Tul. (Fabaceae), Inga edulis Mart. (Fabaceae), Hibiscus rosa-sinensis L. (Malvaceae), Psidium guajava L. (Myrtaceae), Averrhoa carambola L. (Oxalidaceae), Citrus sinensis (L.) Osbeck (Rutaceae) and Solanum lycopersicum L. (Solanaceae), in four municipalities in the north-northeast of the state of Roraima. The plants C. paraensis, I. edulis and C. sinensis are recorded for the first time as a hosts for PHM. Characteristic injuries observed on the host plants infested by PHM and suggestions for its management are presented.
Highlights
The Pink Hibiscus Mealybug (PHM), Maconellicoccus hirsutus (Green, 1908) (Hemiptera: Pseudococcidae) is a polyphagous species of Pseudococcidae that feeds on a wide range of ornamental and agricultural host plant species distributed in 218 genera of 76 botanic families (Ben-Dov et al, 2011).Macroscopically the body of the adult female of M. hirsutus is elongate oval, red-brown to orange-pink in colour, usually 2.5-4.0 mm long, and is covered by white mealy wax
The present paper aims to report M. hirsutus for the first time to Brazil, as well as its parasitoids, dispersion and others host plants in Roraima State
The plants C. paraensis, I. edulis and C. sinensis are recorded for the first time as a hosts for PHM
Summary
The Pink Hibiscus Mealybug (PHM), Maconellicoccus hirsutus (Green, 1908) (Hemiptera: Pseudococcidae) is a polyphagous species of Pseudococcidae that feeds on a wide range of ornamental and agricultural host plant species distributed in 218 genera of 76 botanic families (Ben-Dov et al, 2011). The body of the adult female of M. hirsutus is elongate oval, red-brown to orange-pink in colour, usually 2.5-4.0 mm long, and is covered by white mealy wax. The female secretes a white wax ovisac of irregular shape resembling cotton, on which eggs are laid. The eggs are initially orange in colour, turning pink on maturity. Adult males are orange in colour, smaller than the females, with a pair of wings and two waxy caudal filaments; do not feed, living only a few days to mate (Stibick, 1997)
