Characterization of phospholipase B of Culex pipiens fatigans.

Susceptibility of adults of a Malayan strain of Culex pipiens fatigans Wiedemann to DDT and dieldrin.

Segregation of cytoplasmic incompatibility properties in Culex pipiens fatigans.

Maternally inherited variants, which arose within a laboratory colony of Culex pipiens fatigans, have been studied by rearing cultures from single egg rafts. Segregation, i.e, variation of cytoplasmic incompatibility properties between the male progeny of individual females, was demonstrated. Also, from the daughters of individual females, sub-lines were derived within which all the males showe...

LOCAL PRODUCTION OF PRIMARY POWDER OF BACILLUS THURINGIENSIS SEROTYPE H-14 IN IRAN AND DETERMINATION OF ITS INSECTICIDAL PROPERTIES AGAINST CULEX PIPIENS AND ANOPHELES STEPHENSI

Three media formulated from molasses and cornsteep liquor and another media based on the basal medium formulation of IPS-82 were assessed for the growth and production of insecticidal properties of B. thuringiensis H-14 .• Bacterial powders prepared from the broth cultures were assayed against the larvae of Culex pipiens and Anopheles stephensi. A standard powder of IPS-82 was included in ...

Establishment of a cell line from larvae of Culex pipiens fatigans and its susceptibility to infection with some group C arboviruses.

Os autores relatam o estabelecimento de uma nova linhagem de células obtidas a partir de mosquitos Culex pipiens fatigans colonizados em laboratório. Empregando esta nova linhagem de células foi realizado um estudo comparativo de sua susceptibilidade a cinco arbovírus do Grupo C: Apeu.Marituba, Murutucu, Oribocae Itaqui. Todos os cinco tipos de arbovírus foram capazes de infectar células, demon...

The Effect of Neem (Azadirachta indica) Leaves Extract on the Ecdysis and Mortality of Immature Stages of Common House Mosquito Culex pipiens fatigans

Larvicidal effect of Azadirachta indica on mosquitoes has been studied in the present work. The water extracts of air dried leaves and fresh leaves separately have been used for the study. Different concentrations were made of all these extracts and twenty second instar larvae of Culex pipiens fatigans were placed in each concentration separately. Control was set up for each experiment. Mortali...
