An Orchid Mealybug, Pseudococcus dendrobiorum Williams (Hemiptera: Pseudococcidae)

چکیده
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 viburni). Live specimens of Pseudococcus dendrobiorum most closely resemble the pineapple mealybug in appearance. The presence of a faint dark stripe on the dorsum of the mealybug along with the lack of “long” wax filaments on the tip of the abdomen are common both in D. brevipes and P. dendrobiorum.

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 ...

It is hypothesised here that some mealybug (Pseudococcidae) and root mealybug (Rhizoecidae) prepupae and pupae are mobile. The prepupa and pupa of the mealybug Promyrmococcus dilli Williams and the prepupa of the root mealybug Ripersiella malschae (Williams) are described and illustrated and their probable mobility is discussed. It is also suggested that the prepupae and pupae of the mealybug M...
