Maconellicoccus hirsutus (Hemiptera: Pseudococcidae) in Brazil: recent spread, natural enemies, and new hosts
Abstract
Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) is an invasive and highly polyphagous pest with a worldwide distribution in tropical and subtropical regions. This study reports the geographical distribution, natural enemies, and host plant species of M. hirsutus in Brazil 8 years after its first report in this country. Maconellicoccus hirsutus is now distributed in 11 Brazilian states, in all major geographic regions of the country. Samples (n = 103) of plants infested by M. hirsutus were collected in the state of Espírito Santo, Brazil, with 96% of them found within the isotherm 23 to 27 °C. Hevea brasiliensis (Euphorbiaceae), Theobroma bicolor (Malvaceae), and T. speciosum (Malvaceae) are reported for the first time as hosts of M. hirsutus, and Coccoloba uvifera (Polygonaceae), Morus alba (Moraceae), Punica granatum (Lythraceae), and Talipariti tiliaceum (Malvaceae) are new hosts of M. hirsutus in Brazil. Thirty-seven host plant species of M. hirsutus are now confirmed in Brazil.
Sumario
Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) é praga invasora e altamente polífaga distribuída nas regiões tropicais e subtropicais do mundo. Este estudo relata a distribuição geográfica, inimigos naturais e espécies de plantas hospedeiras de M. hirsutus no Brasil após oito anos de seu primeiro relato. Maconellicoccus hirsutus se encontra distribuída em onze estados em todas as regiões geográficas do Brasil. Foram coletadas 103 amostras de plantas infestadas com M. hirsutus no estado do Espírito Santo com 96% delas encontradas na isoterma 23 to 27 °C. Hevea brasiliensis (Euphorbiaceae), Theobroma bicolor (Malvaceae), e T. speciosum (Malvaceae) são relatadas pela primeira vez como hospedeiras de M. hirsutus, e Coccoloba uvifera (Polygonaceae), Morus alba (Moraceae), Punica granatum (Lythraceae), e Talipariti tiliaceum (Malvaceae) são novas constatações para o Brasil. Trinta e sete plantas hospedeiras de M. hirsutus são agora relatadas no Brasil.
