Parasitization and reproductive capacity of Cotesia flavipes Cameron (Hymenoptaera: Braconidae) on different hosts and instar in laboratory. C. flavipes is an important parasitoid on sugar cane spotted borer, Chilo sacchariphagus Bojer.  The biology informations of C. flavipes is needed in order to make more effective as acontroling agent. The objectives of this research were to investigate the effect of host species (C. sacchariphagus, C. auricilius, Scirpophaga nivella) and different instar on parasitization and reproductive capacity of C. flavipes. The results showed that the best host for                    C.  flavipes is  C. sacchariphagus and at fifth instar of  C. sacchariphagus.

Barringtonia asiatica is one of the plants that the seeds extracts has insecticidal properties. However, the bioactivity of this seed extract has not been tested against Chilo sacchariphagus larvae which is the main pests in sugar cane. The treatment was carried out at several levels of concentration of methanolic seed extract of B. asiatica. The 15 cm of fresh sugarcane shoot dipping into the extract solution in some second. After the solution of extract on the sugarcane shoot dried, the first instar of larvae infested to the sugarcane shoot and then put into 20 cm test tube with 3 cm of diameter.  The duration of feeding on treated sugarcane shoot was two days and on the following day the larvae were fed on sugar cane shoots until the survived larvae reached the 5th instar. The results of the experiment indicated that B. asiatica seed extract was toxic to C. sacchariphagus with an LC50 value of 0.398% at 16 days after treatment. Besides toxic, B. asiatica seed extract also has atifeedant activity, and inhibits the growth of immature of C. sacchariphagus in all tested concentrations.Keyword: Toxicity, antifeedant, lethal concentration, Barringtonia asiatica, Chilo sachariphagus

AbstractLocal parasitoid populations may be adapted to their sympatric major plant host complex. Parasitoid strains may thus differ in their propensity to search for a particular micro-habitat or host or they may differ in their physiological compatibility with particular plant or host species. Cotesia flavipes Cameron, a larval parasitoid used worldwide in biological control against tropical stemborers, has a wide host range in diverse habitats. The existence of plant and/or host specific strains in C. flavipes has been postulated. To provide insight into the existence of strains in C. flavipes, we compared the plant/host complex selection behaviour, and physiological compatibility with different stemborers, of six different geographic strains of C. flavipes that differed in the plant/host complex they were obtained from. The results of the host selection experiments indicate that there is no intraspecific variation in host selection behaviour among C. flavipes strains. However, our comparative experiments show variation in reproductive success among strains. The most significant result was that the strain with the longest period of co-existence with the new host Diatraea saccharalis Fabricius had the highest reproductive success on this host species. We argue that the reported existence of C. flavipes strains is based not on differences in host selection behaviour, but on differences in physiological compatibility between local parasitoid and host population.

KeponeR (decachlorooctahydro-1,3,4-metheno-2H-cyclobuta[cd]pentalen-2-one) is an insecticide effective against ants and roaches. It can cause severe toxicity in fishes, birds, rodents and man. Prominent effects include hepatic lipid deposition and hypertrophy, impairment of reproductive capacity and neurological disorders. Mitochondrial oligomycin-sensitive Mg2+-ATPase is also inhibited. The present study is a preliminary investigation of tissue ultrastructural changes accompanying physiological signs of acute toxicity, which after two days treatment include: pronounced hypersensitivity and tremor, various degrees of anorexia and adipsia, and decreased weight gain.Three different series of adult male Sprague-Dawley rats (Charles River or CD-I) were treated by intubation with Kepone in corn oil at a dose of 50 mg per kg for 3 successive days or at 200 ppm in food for 8 days. After ether anesthesia, rats were immediately perfused via a cannula in the left ventricle with 4% p-formaldehyde and 0.5% glutaraldehyde in Millonig's phosphate buffer at pH 7.2 for 20-30 min at 22°C.
