Identification and eradication of murine fur mite infestations are ongoing challenges faced by many research institutions. Infestations with Myobia musculi and Myocoptes musculinus can lead to animal health problems and may impose unwanted research variables by affecting the immune and physiologic functions of mice. The purpose of this study was to evaluate the utility and efficacy of soiled be...

Virtually every higher animal, including man, is parasitized by species of lice. Pediculosis is important economic problem of many species of livestock (Figure 4) and poultry and at present the lice only be controlled with insecticides (Figure 5). This review deals with the principal classes of insecticides available to control these pests cattle, pigs, sheep and poultry and particular attentio...

BACKGROUND The transportation of camp firewood infested by non-native forest pests such as Asian long-horned beetle (ALB) and emerald ash borer (EAB) has severe impacts on North American forests. Once invasive forest pests are established, it can be difficult to eradicate them. Hence, preventing the long-distance transport of firewood by individuals is crucial. METHODS Here we develop a stoch...

I read the recent article by Basu et al(1) with a great interest. The authors described an interesting case of ocular cysticercosis manifesting with ptosis. Indeed, ocular cysticercosis is not a rare disease in the developing countries, and ptosis due to cysticercosis is sporadically reported. Sekhar et al reported that subconjunctival cyst might be related to ptosis and suggested that the surg...

A computer software system is described that uses digitized color information from aerial color infrared transparencies to detect the presence of citrus mealybug (Pseudococcus citri Risso), brown soft scale (Coccus hesperidum L.), and Rio Grande gummosis in individual citrus trees. The color coordinates at each spatial point, and color differences at adjacent points are used to locate the trees...
