The role of cockroaches and flies in mechanical transmission of medical important parasites
Arthropods can be found on human or animals as ecto-parasites. Vectors can contaminate stored foods and transmit illness, or introduce diseases in new areas. Pet species facilitating infestations, and different risk factors related to infestation were identified. To determine the possible role of insects in dissemination of medically important parasites, study was carried out in residential areas of...

Density-dependent phenotypic plasticity in body coloration and morphometry and its transgenerational changes in the migratory locust, Locusta migratoria
Migratory locust, Locusta migratoria (Orthoptera, Acrididae) changes phase in response to population density. By rearing nymphs from a solitarious (isolated-reared) and gregarious line at three different densities, we examined the effects of rearing density on body coloration and morphometry at the last nymphal instar, adult stage and hatchlings of the subsequent generation. Changes in density lead...

Bio-efficacy of synthetic chemicals, botanicals and microbial derivatives against scale insect Coccus hesperidum Linn. in arecanut
Ignorance of plant protection in areca palms at early stages can cause considerable loss from the sucking pests, particularly, Coccus hesperidum Linn. (Hemiptera: Coccidae) during unfavorable weather conditions. In order to overcome this, replicated field trials at five different locations were conducted during 2008/2009 and 2009/2010. Synthetic chemicals (chlorpyriphos 20 EC at 2.5 ml/l, endosulfan...
