A new monotypic genus and species, Komodesia circuliplurimagen. et sp. n., from Flores Is. (Indonesia) and the new species, Antonina diversiglandulosasp. n., from Southern Thailand are described and illustrated. Chromosomes of these species and also the ones of Antonina purpurea Signoret, 1872 and Antonina thaiensis Takahashi, 1942 are studied for the first time: 2n = 30, 20, 12 and 22+Bs corre...

Recently, several invasive mealybugs (Hemiptera: Pseudococcidae) have rapidly spread to Asia and have become a serious threat to the production of cotton including transgenic cotton. Thus far, studies have mainly focused on the effects of mealybugs on non-transgenic cotton, without fully considering their effects on transgenic cotton and trophic interactions. Therefore, investigating the potent...

The physiological role of microbial surfactants production in microorganisms includes antimicrobial activity and break down of complex hydrocarbon substances to make the substrates readily available for uptake in adverse environmental conditions. Wax degrading bacteria are a significant group of microorganisms facilitated mainly by the production of microbial surfactants to emulsify waxy substa...

Vapor heat treatments were developed against life stages of the mealybug Maconellicoccus hirsutus (Green) (Homoptera: Pseudococcidae). Treatments tested were 47 degrees C for 5-50 min in 5-min increments and 49 degrees C for 3, 5, 8, 10, and 12 min. All tests were conducted with mixed age M. hirsutus on Chinese pea, Pisum sativum L. Treatment at 47 degrees C required 45 min to kill all M. hirsu...

Twenty-two species of legged mealybugs occur on bamboo (Poaceae: Bambusoideae) in China. These species are reviewed and two of them are described for the first time: Dysmicoccus luoyangensis Li & Wu, sp. nov. and Trionymus indocalamus Li & Wu, sp. nov. Two new combinations are established: Pseudococcus bambusicola Takahashi and Kaicoccus bambusus Wu are transferred to genus Formicococcus Takaha...

Five mealybug (Hemiptera: Pseudococcidae) plant pest species: Dysmicoccus grassii (Leonardi), Ferrisia malvastra (McDaniel), Ferrisia virgata (Cockerell), Phenacoccus tucumanus Granara de Willink, and Pseudococcus elisae Borchsenius are recorded for the first time in the state of Espírito Santo, Brazil. These are the first records of D. grassii in Brazil, from papaya (Carica papaya, Caricaceae)...
