摘要:

AbstractIn the present research, the venation of 53 species of Tortricinae (Lepidoptera) known from Japan was analyzed using image analysis technique. A method to use the new character “vein points” for species identification was established, and a corresponding expert system was developed. In this method, the X and Y pixel coordinates of 22 “vein points” of the forewing of Tortricinae were measured and then used as a main character. By statistical analysis, the “vein points” were proved to be able to reflect the venation pattern stably and accurately. These “vein points” were input into a personal computer. Let the computer measure the X and Y coordinates of each “vein point” automatically, and calculate the dissimilarity among 22 “vein points” of the specimen and those of the known Operational Taxonomic Units (OTUs), and display the names of the known OTUs in order of increasing dissimilarity. As a result of simulation tests on the expert system, 98. 2 percent of the correct answers ranked Ist, the remaining 1.8 percent ranked 2nd and 3rd. In order to reach a 100 percentage of correct answers, other image and literal information of the 53 species were also input into the identification system as references. These informations include morphological figures of adult Tortricids, genitalia of males and females, literal description about morphology, habitat, distribution, host and so on. Using this expert system, people other than taxonomists can also identify specimen of Tortricinae to species accurat

摘要:

AbstractThe present paper deals with a new species,Heratemis ustulatusWuetChen, collected from Fujian Province. The new species is distinguished easily from the closely related speciesHeratemis uegeta(Papp) by the following characters: head blackish‐brown, mesonotum reddish‐brown, length of ovipositor equal to abdomen. Type specimen is deposited in Beneficial Insects Lab., Fujian Agricultural University, Fuzhou, Fujian Provi

摘要:

AbstractThe present study shows that 20‐hydroxyecdysone(20‐OHE) participates in the humoral immune responses ofPhilosamia Cynthia ricini, either normal or debrained pupae, to the E.coli. The mode of action of 20—‐OHE is multiple. It raises hemolymph protein content, makes antibacterial proteins be produced, increases lysozyme activity, and activates prophenoloxidase system. It is possible that several immune control systems are i

摘要:

AbstractThe behavioral responses of the female adult parasitoidsLysiphlebia japonicato plant volatile chemicals, host plants and cotton aphids were tested in a four arm air flow olfactometer. The results indicated that the female parasitoids were strongly attracted by the odors from cotton aphids and their host plants. Damaged cotton leaves were more attractive than intact ones. Among the four olfactory stimuli from the plant volatile chemicals dissolved in liquid paraffin oil at the concentration of 0.01 (volume fraction), the female parasitoids only positively responded to benzaldehyde, but did not show any preference to β‐caryophyllene and β‐pinene. Although heptanol elicited the highest EAC response of the parasitoids, the behavioral test showed that it repelled the parasitoids, and β‐pinene shared the same feature with heptanol at the concentration of 1 (volume fraction). Our results also showed that the female parasitoids only preferred the cotton leaf from which the mummified aphids were collected, and did not express any interest to the three plants of melon family in the olfactometer, The possible mechanisms are d

摘要:

AbstractThe sex attractant pheromone of the tea tussock moth, a serious economic pest of tea plantations in southern China, has been identified as 10,14‐dimethylpentadecyl isobutyrate. A synthesis of the racemic form of the pheromone was developed, and traps baited with the synthetic compound at doses of 40–1000 micrograms captured male moths. The synthetic pheromone was as effective as a trap bait as, virgin female moths, or extracts of female mo
