Antennal surface structure of Pteromalus puparum L. was observed by scanning electron microscope. Seven types of sensilla, namely, thick-walled chemoreceptor, thin-walled chemoreceptor, plate organ, short-curved tactile hair, sharp-tipped tactile hair, basiconic capitate peg and chaeticum sensillum...

Vitellin was isolated and purified from the eggs of a water wolf spider, P. piraticus. The final preparation is existed only in reproducing females as judged by polyacrylamide gel electrophoresis and immunodiffusion method. The vitellin was defined as glycolipoprotein. The isoelecctric point is pH 6...

Temporal patterns of vitellogenin (Vg) synthesis and uptake as well as vitellin (Vn) degradation in Nasonia vitripennis (Hymenoptera: Pteromalidae), an ectoparasitic wasp of fly pupae, were studied using the method of enzyme-linked immunosorbent assay (ELISA). The results were showed as follows: the...

The development profile of soluble hemolymph proteins was analyzed by the gradient SDS-polyacrylamide gel (5%-20%) electrophoresis during the larval and pupal stages of Aldrichina grahami (Aldrich) which was kept at 24℃. Twelve distinct component bands with a molecular mass range of approx. 11-230 k...

The female reproductive system of Chrysoperla sinica was divided into 5 developmental grades according to its anatomic characteristics, and this was verified by the analytical results of the biochemical compositions including nucleic acid, protein, phospholipid etc. in the different gradational ovar...

The pseudoparasitism method was used to evaluate physiological activities of some factors from female adults of Pteromalus puparum (Hymenoptera: Pteromalidae). As a small white butterfly, Pieris rapae pupae were pseudo-parasitized by female wasps of Pteromalus puparum exposed to γ-ray irradiation wi...

Effects of TT9-3 and TT9-4, which are two homozygous strains of transgenic Bt rice, on the dispersal of planthoppers and leafhoppers as well as their egg parasitic wasps were evaluated in the field. The results were as follows: there were two species of planthoppers and three species of leafhoppers...

The survival, growth and development as well as reproduction of Boettcherisca peregrina (Diptera: Sarcophagidae) in the parental generation were significantly influenced as newly oviposited larvae were exposed to various concentration of Cd²⁺ administered in the artificial die...

The lethal and sub-lethal effects of a transgenic rice line KMD1, containing a synthetic cry1Ab gene from Bacillus thuringiensis measured on larvae of striped stem borer, Chilo suppressalis (Walker) is reported in this article. The transgenic rice line was highly toxic to the 1st, 3rd and 5th instar...

The parasitization by Nasonia vitripennis (Hymenoptera: Pteromalidae) could result in marked changes in hemocyte population and composition and level of soluble proteins as well as the soluble sugar level in the hemolymph of Boettcherisca peregrina pupae. Total hemocyte counts and the counts of plas...

We determined the preferences of feeding and oviposition of the brown planthopper (BPH), Nilaparvata lugens, to rice plants of IR64 with different nitrogen content, the changes in preferences of BPH populations fed successively on plants with high (200N) or low (0N) nitrogen fertilizer, and the infl...

Influences of 10 insecticides at commercially recommended dosage on survival of Pteromalus puparum female adults, as well as 4 of them on the ovarian development of surviving adults, were evaluated in laboratory using dry film bioassay. Based upon the mortality of treated adults, phoxim and chlorpyr...

In Boettcherisca peregrina, changes in the activities of three species of antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) were measured together with patterns of cuprum or cadmium accumulation as the newly hatched fly larvae were exposed to the diet cont...

The effect of parasitism by Pteromalus puparum (Hymenoptera: Pteromalidae) on trehalase activity and contents of soluble protein, total sugar, trehalose and reducing sugar in the hemolymph of overwintering pupae of Pieris rapae was investigated. When overwintering Pieris rapae pupae were parasitized...

The ultrastructures of fat bodies before and during vitellogenesis and of follicles at different developmental stages in the parasitoid Pteromalus puparum were studied by electron microscope. At previtellogenic stage (that is, at pupal stage), large amounts of protein granules and mitochondria were...

Available information on the microbial mechanisms associated with heavy metal (HM) passivation during co-composting amended with phosphate rock (PR) remains limited. Thus, this study investigated the dynamic changes in bacterial communities and HM-fractions (Zn, Cu, Cd, Cr and Pb) during swine manur...
