Note on a Flagellate Parasite found in Culex fatigans

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...

Characterization of phospholipase B of Culex pipiens fatigans.

Phospholipase B has been found in the mosquito Culex pipiens fatigans, and some of its properties have been studied. The enzyme had a high optimum temperature (45 degrees C) and broad alkaline pH optimum (8-9). It was inactive toward diacylphospholipids, and hydrolyzed lysolecithin at a higher rate than lysophosphatidyl ethanolamine. The enzyme was heat labile, but lysolecithin protected it aga...

Quantitative Analysis of DDT by GLC in Different Strains of Culex Fatigans L. by Using Hexane

Estimation of DDT by GLC (gas liquid chromatography) in K.U. strain of Culex fatigans L., shows that 59.68 ng DDT is found after the treatment with 0.175 ppm. In G.I. strain 18.3 ng DDT is found after treatment with 0.325 ppm whereas 4.35 ng DDT is found in L.Y. strain after the treatment with 0.425 ppm.
