    Results from a behavioral study by using a four-armed olfactometer (Vet et al, 1983) showed that Mate and apterous virginopara of Aphis glycines were clearly attracted or arrested by volatiles from Glycine max, its secondary hostplant, and Rhamnus davurica, its primary hostplant. The attractiveness of G.max was greater than that of R. davurica. Chemical analysis indicated that there is some difference in the volatile profiles between these two plant species. The volatiles from two nonhost plant species Gossypium hirsutum and Cucumis sativa, which are the most suitable hostplants of another aphid A. gossypii closely related to A. glycines, werefound to be neutral. However, the odors of Luffa cylindrica and Cucurbita peposignificantly repelled the Mate virginopara of A. glycines. Thus, the olfactory response of A. glyeines to these host and nonhost plants implies the evolutionary transition of A. glycines in hostplant specificity. Blending the odors from nonhost plants Gossypium hirsutum, Luria cylindricaand Cueurbita pepo with the attractive odor of hostplant G. Max blocked the attraction of the latter to the alate virginopara of A.glycines. It thus appeared that attraction of host plant to aphids can be disrupted by the presence of nonhost plant volatiles which have presumably masked the host plant odor and the lack of attraction of the blended odors is caused by the change in volatile prolife.

    Laboratory bioassay and field trapping tests were carried out on four syntheticoptical isomers of 4,6,10,12-tetramethyl-2E,4E-tridecadien-7-one 1, the sex pheromone of the pine scale Matsucoccus matsumurae. The results showed that only 6R,10R-4,6,10,12-tetramethyl-2E,4E-tridecadien-7-one elicited strong attraction to the male adults and was assigned as the absolute configuration of the naturally occurring sex pheromone of this pine scale.

    The endogenous enzymes of protective system including superoxide dismutase(SOD), peroxidase (POD) and catalase (CAT) were found to exist in the larvae of Pieris rapae. The level of SOD activity of the larva was closely correlated with the instars. After applying deltamethrin to the larvae, the levels of SOD, CAT and PODactivity were found to be higher than that of the control within one hour. When deltamethrin was applied to the slug caterpillars Parasa consocia and Thosea pastornata, the SOD and CAT activities were enhanced gradually with the degree of poisoning, but declined rapidly near death. However, the SOD and CAT activities in the slug caterpillars survived from the deltamethrin treatment were higher than that of the control, showing that SOD and CAT activities were correlated with tolerance to insecticide.

    The efficacy of Bacillus sphaericus C3-41 to control the larvae of Culex quinquefasciatus was evaluated in the laboratory. The result indicated that the strain C3-41 was a very effective control agent against the mosquito larvae. The 50% lethal dosage (LD50) against the second to fourth larval instar were found to be 63.1 and 89.7 sporesper larva respectively. The larvicidal substance ingested by larvae seemed to be directly proportional to the concentration of C3-41 and duration of feeding time. When larvae ingested subAethal dosage of B. sphaericus, its recycling could not occur in the living larvae. However, when the larvae ingested lethaldosage, they died within 48 hours and recycling of the bacteria occurred immediately. The number of spores increased from initial 1.86X102to1.59X106 sporesper larva within six days after the death of the larvae. The spores germinated, multiplied, sporulated and forming toxin normally in larval cadavers. The spores yielded in larval cadavers were highly toxic to the mosquito larvae.

    The insecticidal activity of the essential oil from Artcmisia scoparia (Asteraceae)against Sitophilus zeamais was determined. By means of GC-MS analysis, 92 constituents were separated from the essential oil and 46 of them were identified. The predominant component of the essential oil was isolated and identified to be l-phenyl-2,4-hexadiyne which was found to be responsible for the insecticidal activity of the essential oil.

    Respiration rates of Chorthippus dubius(Zub.) were determined by use of an infrared carbon dioxide analyzer at different temperatures. All 5 nymphal instars and both sexes of adult were investigated. Results of regression analyses of dry bodyweights vs. oxygen consumption at 10-30℃ gave slope values ranging from 0.75 to 0.87. Regression analyses of oxygen consumption rates per unit of body weight showed that Krogh's formula could be applied to the nymphs in second or thirdinstars and Arrhenius' equation at the other stages. No statistically significant difference in diurnal and nocturnal respiration rates at the same temperature was observed. According to the regression equations between oxygen onsumption and temper- ature, coupled with the observations of population biomass and mean ambient air temperature, we computed the oxygen consumption by the relative population in the three plant communities. The Wightman's coefficient of 2.58 was adopted to correct the population oxygen consumption value, considering the difference of respiration of the animal in the laboratory and in the field. An oxycaloric coefficient of 20.22 (J./ml) was used to convert the oxygen consumption to calories. This resulted in the population respiration of 4.65KJ in the Aneurolepidium ehinense+Stipa grandis+Agropyron michnoi community, 3.99KJ in the Artemisia frigida community and 2.33KJ in the Aneurolepidiura chinensis community.

    The age-stage-specific life table that incorporates variable developmental rate among individuals and male adults is reported for the armyworm, Mythimna separata (Walker), reared on young corn leaves at 23℃. The method of its construction is diagramed, according to which, the net reproduction rate of the worm population(R0) was calculated to be 155.88; the intrinsic rate of increase (rm), 0.1120; and the mean generation time (T), 45.08. Days. All values of these parameters are somewhat different from those obtained by means of the traditional age-specific life table,and the cause of such differences is analysed. Advantage of the new life table incomparison to the traditional one is briefly discussed.

    he wing microsculpturing in three species of Kalotermitidae (Cryptoterrnes pingyangensis, C. havilandi, lncisitermes laterangularis) and two species of Hodotermitidae (Hodotermopsis orientalis, H. yui) was studied by scanning electron microscopy. The types of microsculpturing found are as following: papillae: width 5.0-20.61μm, length 3.0-17.7μm, with density of about 2070-3575 papillae/mm2 at the central wing surface; tubercles: diameter 15.0-586μm, with density of about282-356 tubercles/mm2 at the central wing surface; pimpules: diameter 2.4-4.8μm.Besides these, hairs with 11-57μm long were also found. There was no obvious difference between the fore-and hind-wing and between the ventral-and dorsal-surface of the wings. The systematic and biological significance of the wing microsculpturing in termites is discussed.

    There are 6 species of aphid flying and migrating to tobacco plants in the region of cultured tobacco in the north of Wei River, Shaanxi Province, but only Myzus persicae (Sulzer) can do damage to tobacco. Tobacco plants are divided into grade 0, I, II, III and IV according to the aphid quantity per plant in the period of its serious damage, and leaf area polluted by mould caused by honey dew secreted by the aphid in the period of tobacco ripening. Compared with grade 0 not injured by the aphid, the mid-and high-grade tobacco leaves in grade I,II,III and IV injured by the aphid are reduced by 6.93%, 13.05%, 28.51% and 30.94% respectively. The economic losses caused by the aphid are 9.86%, 23.81%, 36.12% and 39.59% respectively. The analyses of chemical composition indicate that nicotine of the leaves in grade I,II, III and IV is reduced by 10.61%, 19.29%, 10.61% and 25.40%, reducing sugar is reduced by 15.04%, 19.23%, 40.78% and 44.86%, and protein are increased by 16.17%, 31.77%, 37.02% and 38.72% respectively. These show that both the external and internal qualities of the flue-cured tobacco leaves are influenced by the aphid injury. The economic loss of one aphid is about 0.0695%.

    This paper presents the results of mathematical analysis of DV/D ratio of male genitalia of Culex pipiens complex, including 23 geographical strains collectedin China. Through mathematical analysis, particularly the multiple linear regression,the DV/D ratio showed a negative correlation with latitude and longitude of their locations, and the multiple regression equation of DV/D ratio between latitude and longitude were established. This equation can be used to conjecture the theoretical value of DV/D ratio of Cx. Pipiens complex at a geographical position in China.

    This paper deals with the biology and distribution of Stenogastridae in southernChina. Stenogastricae wasps are small and rather inconspicuous insects with primitive social organization. Four species belonging to four genera were formerly reported in China. According to our investigation in some counties of southern China,10 species belonging to four genera were found and a new genus will be reportedelsewhere. The habitats and nest construction of the Stenogastridae wasps were observed and they could be divided into living in the field and living within human residence. The density of nests of Parischnogaster mellyi was 8.25 per residence onaverage, ranging from 2 to 16. The wasps do not hibernate in winter and can build their nests, feed on prey and breed throughout the whole year. They are distributed in tropical and subtropical southeastern Asia and New Guinea, from India to China including the northeastern region of Guizhou Province.
