With the incidence of Lyme disease increasing throughout the United States, reducing risk of exposure to the disease is of the utmost concern. In the northeastern U.S., the blacklegged tick, Ixodes scapularis, is the primary vector and the white-footed mouse, (Peromyscus leucopus), the primary reservoir for Borrelia burgdorferi, the bacterium causing Lyme disease. Targeting I. scapularis engorg...

a suitable diet and oviposition substrate are two basic needs for successful mass rearing of orius spp. and this may reduce their production costs. the effect of various foods containing eggs of ephestia kuehniella and sitotroga cerealella with various pollens were investigated on the biological parameters of o. albidipennis in the laboratory. moreover, survival, hatching rate and fecundity of ...

WEBSTER, J. M. 1973. Manipulation of environment to facilitate use of nematodes in biocontrol of insects. Experimental Parasitology 33, 197-206. The preand postparasitic phases of entomophilic nematodes are exposed to different microenvironments which should be changed in order to facilitate the use of nematodes as biological control agents of insects. The mixing of “thick water” with nematodes...

Population control of the dengue vector mosquito, Aedes aegypti, is difficult due to many reasons, one being the development of resistance to neurotoxic insecticides employed. The biosynthesis of chitin, a major constituent of insect cuticle, is a novel target for population control. Novaluron is a benzoylphenylurea (BPU) that acts as a chitin synthesis inhibitor, already used against mosquitoe...

Nilaparvata lugens harbors yeast-like symbionts (YLSs). In present paper, a genome-wide analysis found 115 genes from Ni. lugens and 90 genes from YLSs that were involved in the metabolic degradation of 20 proteinogenic amino acids. These 205 genes encoded for 77 enzymes. Accordingly, the degradation pathways for the 20 amino acids were manually constructed. It is postulated that Ni. lugens can...

B. burgdorferi–infected I. scapularis now includes northern Cook and Lake counties. More importantly, the high percentage of B. burgdorferi–infected ticks in this region confi rms a newly recognized signifi cant risk of Lyme disease in suburban areas adjacent to Chicago (population ≈7 million). Recently, the Infectious Diseases Society of America recommended that clinicians consider prescribing...

The life cycle of Rhipicephalus evertsi evertsi Neumann, 1897, is discussed under the following headings: larval feeding; larval drop; nymphal feeding; nymphal drop; nymphal moulting; adult feeding; adult drop; preoviposition period; oviposition period and incubation. Special attention has also been given to the development of both male and female reproductive organs, gametogensis and mating.
