Molecular and Morphological Identification of Mealybug Species (Hemiptera: Pseudococcidae) in Brazilian Vineyards

Mealybugs (Hemiptera: Pseudococcidae) are pests constraining the international trade of Brazilian table grapes. They damage grapes by transmitting viruses and toxins, causing defoliation, chlorosis, and vigor losses and favoring the development of sooty mold. Difficulties in mealybug identification remain an obstacle to the adequate management of these pests. In this study, our primary aim was ...

A multiplex PCR assay for the simultaneous identification of three mealybug species (Hemiptera: Pseudococcidae).

Molecular species identification is becoming more wide-spread in diagnostics and ecological studies, particularly with regard to insects for which morphological identification is difficult or time-consuming. In this study, we describe the development and application of a single-step multiplex PCR for the identification of three mealybug species (Hemiptera: Pseudococcidae) associated with grapev...

Molecular Evidence of Polyandry in the Citrus Mealybug, Planococcus citri (Hemiptera: Pseudococcidae)

The occurrence of polyandry in Planococcuscitri, presumed by earlier observations of mating behavior, was confirmed using microsatellite genotyping of pools of over 400 eggs resulting from controlled crosses of one female with two males. The genetic contribution of both mated males was confirmed in 13 out of 43 crosses. In three crosses it was possible to determine that only the first male fert...

A new record of mealybug pest in the south of Iran, Phenacoccus solenopsis (Hemiptera: Coccoidea: Pseudococcidae)

شپشک آردآلود Phenacoccus solenopsis Tinsley در تاریخ 12/10/1387 از بندرعباس و میناب در استان هرمزگان از روی ختمی چینی Hibiscus rosa-sinensis جمع‌آوری شد. این شپشک که برای اولین بار از ایران گزارش می‌شود، در پاکستان و هند یکی از آفات خسارت‌زا روی محصول پنبه است و سالانه مبالغ هنگفتی صرف کنترل شیمیایی آن می‌گردد. این شپشک خسارت قابل ملاحظه‌ای به گیاهان زینتی در شهرها و درختان میوه، به‌ویژه مرکبات...
