Abstract:
... The southern cattle tick Rhipicephalus (Boophilus) microplus (Bm) is a vector of bovine babesiosis and anaplasmosis. Tick resistance to organophosphate (OP) acaricide involves acetylcholinesterase (AChE) insensitivity to OP and metabolic detoxification. Sequencing and in vitro expression of Bm genes encoding AChE allowed biochemical characterization of three BmAChEs expressed in tick synganglion. ...

It predisposes American beech (Fagus grandifolia Ehrhart) trees to infection by Neonectria spp. Fungi causing beech bark disease. White wax secreted by the diminutive scales obscures individual insects, making it difficult to accurately quantify ...

Abstract:
... Malaria is an urgent world health concern and vector control is one important option for reducing disease prevalence. Increased reports of pyrethroid-resistant mosquito strains have amplified the need for new vector-control chemicals. We compared three commercially available carbamate insecticides (carbofuran, bendiocarb, and propoxur) to eight experimental compounds 1–8 for activity against Anoph ...

Abstract:
... Feeding on above- and belowground plant tissues by Tipula paludosa Meigen during the period of rapid growth from second to forth instars is highly damaging to cool-season (C3) turfgrasses. It may be possible to reduce this damage by identifying grass genotypes that increase host plant protection. This study examined the impacts of plant genotype, endophyte infection, and plant ontogeny on host pla ...

Pollination problems result in low seed yields. This problem is accentuated when male sterile lines (MSL) are used to produce hybrid onion seeds. In this study, the effect of floral attributes and nectar composition on the preference of honey bees of ...
