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...

In the swampy floodplains of North Carolina’s Black River stand ancient trees with a story to tell. Many of these bald cypress (Taxodium distichum) were well over a millennium old when Columbus discovered the Western Hemisphere. As it turns out, their locale has greatly promoted their longevity: by being relatively inaccessible, the trees have been spared from loggers’ saws. But the inexorable ...

ABSTRACT Closterovirus-like particles associated with mealybug wilt of pineapple were acquired and transmitted by the pink pineapple mealybug, Dysmicoccus brevipes, and the gray pineapple mealybug, D. neobrevipes. Mealybugs acquired pineapple mealybug wilt-associated virus (PMWaV) from infected pineapple plants or detached leaves. The virus was detected in plants by tissue blot immunoassay and ...

Cypress tree with blue green foliage and scaly reddish brown bark is planted throughout world as an ornamental plant. One of the newest ways for determining amount and kind of environmental pollutants is natural biomonitoring. The samples were obtained from three sites (heavy traffic, moderate traffic and control) in Isfahan during August-September and November-December 2013 and February-March ...

Remote sensing was used to attempt to define the areal extent of the introduced tree Y1elaleuca quinquenervia in selected portions of south Florida. The area occupied by Y1elaleuca has increased markedly in recent years, in part because of populationinduced site modifications including hydroperiod changes resulting from artificial dminage, cutting of the native vegetation, and burning. LANDSAT ...

Microscopic localization of endosymbiotic bacteria in three species of mealybug (Pseudococcus longispinus, the long-tailed mealybug; Pseudococcus calceolariae, the citrophilus mealybug; and Pseudococcus viburni, the obscure mealybug) showed these organisms were confined to bacteriocyte cells within a bacteriome centrally located within the hemocoel. Two species of bacteria were present, with th...
