the ovipositiomil behaviour and success of anagyrus pseudococci (girault), an encyrtid endoparasitoid of mealybugs, planococcus citri (risso) and pseudococcus affinis (mask.) were studied in the laboratory. behavioural sequences during oviposition starting from the searching for the host to the post-oviposition activities were described. once encountered, the mealybug host was examined and ...

The research is based on the unique collections of tropical and subtropical plants MBG. Phytosanitary monitoring was carried out in laboratory «Tropical Subtropical plants»: Orangery, glass greenhouse Korean greenhouse. As a result phytosanitary complex MBG, next pests were identified: Trialeyrodes vaporariorum Westw.; Pseudococcus affinis Mask.; Diaspis boisduvalii Sign.; Tetranychus urticae L...

SIMILAR MEALYBUGS: There are several mealybugs that are reported as occurring on orchids, and in Florida the most commonly encountered mealybugs on orchids are: pineapple mealybug (Dysmicoccus brevipes), longtailed mealybug (Pseudococcus longispinus), Jack Beardsley mealybug (Pseudococcus jackbeardsleyi), orchid mealybug (Pseudococcus microcirculus) and the obscure mealybug (Pseudococcus viburn...

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 ...

The literature concerning the association between ants and the mealybugs causing pineapple wilt disease is surveyed. A great deal of data on this subject has been published in the relatively obscure technical papers and reports of the defunct Pineapple Research Institute of Hawaii. This review article is an attempt to bring this information to a broader audience and examine it in the context of...

A new species of mealybug from Chile, Pseudococcus meridionalis Prado sp. n., is described and illustrated based on the morphological and molecular characterization of adult females. This species belongs to the “Pseudococcus maritimus” complex and displays a wide host plant range, including Japanese pear, persimmon, pomegranate, pear and grape.

Inbreeding depression is a major concern in almost all human activities relating to plant and animal breeding. The biological control of pests with natural enemies is no exception, because populations of biocontrol agents experience a series of bottlenecks during importation, rearing, and introduction. A classical biological control program for the Comstock mealybug Pseudococcus comstocki (Hemi...

A simple molecular tool was developed and tested to identify seven mealybug species found in North American vineyards: Pseudococcus maritimus Ehrhorn, Pseudococcus viburni (Signoret), Pseudococcus longispinus (Targioni-Tozzeti), Pseudococcus calceolariae (Maskell), Planococcus ficus (Signoret), Planococcus citri (Risso), and Ferrisia gilli Gullan. The developed multiplex PCR is based on the mit...
