This study aimed to evaluate the yield and chemical composition of essential oils from Croton blanchetianus Sida cordifolia, in addition investigating insecticidal potential these on adults bean weevil, Callosobruchus maculatus. To obtain oils, hydrodistillation method was adopted, using a Clevenger apparatus. The identification quantification constituents performed by means gas chromatography ...

Seventy-three nyalas (Tragelaphus angasii) in the Umfolozi, Mkuzi and Ndumu Game Reserves in northeastern KwaZulu-Natal were examined for arthropod parasites during 1983 and 1984. In addition, six animals were examined during 1994. Ten ixodid tick species, two louse species and a louse fly species were recovered. The nyalas were good hosts of all stages of development of Boophilus decoloratus, ...

The morphologically diverse leafhopper tribe Hyalojassini is reinstated from synonymy under Iassini based on distinctive features of the male genitalia and a key to the Oriental genera is given. The previously monotypic genera Hyalojassus Evans and Coriojassus Evans are revised and redescribed based on study of the type species. The following new genera and species are described from Thailand a...

in last two decades, considerable attempts have been made to introduce new botanical based insecticides. in this study, repellent effects of the essential oils taken from lavandula angustifolia and zataria multiflora on callosobruchus maculatus adults were evaluated. the essential oils were extracted using a clevenger apparatus. bioassays were conducted under 30±1ºc, 60±5% rh and dark condition...

Camallanus tridentatus is redescribed on the basis of the examination of specimens obtained from the stomach, caeca and intestine of the naturally infected arapaima Arapaima gigas (Schinz) from the Mexiana Island, Amazon River Delta, Brazil. Data on the surface morphology of adults inferred from confocal laser scanning and scanning electron microscopical observations are also provided. The stud...

The larvae and larval development of Galaxias maculatus are described from a freshwater lake and a saline river in southwestern Western Australia. The size at hatching (7.0 mm total length) was similar to that recorded elsewhere for G. maculatus and the sequence of fin development (i.e., caudal, dorsal, anal, pectoral, and pelvic fins) was identical to that recorded for galaxiids generally. The...

The Probe trap was tested with three types (empty, water, alcoholic extract of (Vicia faba) respectively and for periods time (1, 2, 3) days to catch the cowpea weevil C. maculatus that infests broad bean seeds prepared cultivation. It gave a catching percentage on third day placing traps (19.16, 62.5, 88.33)% respectively, lowest first (5.83, 20, 41.67%) while highest Indicator device species ...
