The sugi bark borer, Semanotus japonicus, occurs naturally in Honshu, Shikoku, Sado Is., Oki Is., and Yaku Is. in Japan, and its main host tree is the Japanese cedar, Cryptomeria japonica. Because the geographical structure of the morphological characters largely corresponds to the sites of the glacial refugia and the post-Pleistocene dispersal route of the Japanese cedar, the history of the cedar was postulated to have shaped the genetic population structure in the borer. In this study, we used partial sequences from mitochondrial DNA genes, the COI, tRNALeu-UUR and COII to elucidate processes in the geographical structuring of S. japonicus populations. Ten haplotypes were revealed among 52 individuals from four populations that ranged from Iwate to Ehime prefectures. The geographical distribution of these haplotypes was highly structured. Two distinct lineages were detected, which probably represented the Pacific coastal and the Japan Sea side lineages, from the neighbour-joining method and haplotype networking. As haplotypes of both Pacific and Japan Sea lineages were found in the Iwate population, a second contact might have occurred in the Tohoku area. These results suggested that the present genetic structure of S. japonicus was determined by the host's past history.

A simple mass-rearing method for the fruit-feeder type yellow peach moth, Dichocrocis punctiferalis GUENEE, was established with an oviposition device and an artificial diet.The oviposition device was a ball-type tea strainer (diam. 8 cm) which contained a small green fruit as an odor source and was wrapped with cheese cloth. The artificial diet consisted of meal powder for mouse, soybean meal powder, dry wood powder, ascorbic acid, agar powder, and water. The average cocoon-yield was 39.4% of eggs inoculated.

Facultative parthenogenesis, or condition-dependent alternation of sexual and asexual reproduction, is widespread in animals. Parthenogenesis enables unmated females to reproduce and thus has a great adaptive significance, especially under low pairing efficiency. In the termite Reticulitermes speratus Kolbe, females that fail to pair with males found colonies cooperatively with partner females and reproduce parthenogenetically. We compared the quality of parthenogenetic and sexual eggs in terms of size, hatching rate, and hatching period. We developed a method to culture isolated eggs until hatching under sterile conditions and in appropriate humidity. We successfully isolated, sterilized, and maintained the eggs on agar plates containing 200 ppm tetracycline. Females of female-female (FF) pairs began to lay eggs at the same time as those of female-male (FM) pairs. Nevertheless, the parthenogenetic eggs were significantly larger than sexual eggs. While the two types of eggs had similar hatching rates, parthenogenetic eggs had longer hatching periods (36.36±0.16 [SE] days) than sexual eggs (34.95±0.12 SE). We conclude that primary queens invest more resources into each parthenogenetic egg than each sexual egg, and that parthenogenetic eggs are as viable as sexual eggs.

The developmental success and the oviposition of the Kanzawa spider mite, Tetranychus kanzawai KISHIDA, on 44 species of plants were studied for four populations collected from tea, pear, hydrangea and kudzu vine. Of the plants tested, 14 were common hosts of the four populations. The tea plant was utilized only by the tea population, and the hydrangea plants only by the pear and hydrangea populations. These three populations could utilize the kerria plant, while the kudzu population could not. In intrapopulation crosses, all populations produced both female and male progeny. Inter population crosses among the three (tea, pear and hydrangea) populations were successful. However, female mites of the kudzu population were reproductively incompatible with males from all of the other populations. Thus, it was concluded that T. kanzawai consists of the tea-associated, the hydrangea-associated (pear and hydrangea), and the kerria-avoiding (kudzu) populations. In addition, the kudzu population was determined to differ in reproductive traits from the other populations.

Larvae of lacewings developed into adults on four chemically defined diets of different amino acid composition. The diets were composed of 23 amino acids, sucrose, trehalose, 5 organic acids, 6 fatty acids, cholesterol, 11 mineral salts, and 17 vitamins. The adults on the best diet produced more than 1, 000 eggs over 2 months.

Relative toxicity of 14 insecticides was examined by the topical application. Test animals were two rice pests : Nephotettix cincticeps and Chilo suppressalis, and their predators : Lycosa pseudoannulata and Conocephalus maculatus. The relative toxicity of insecticides was expressed in terms of the ratio of LD50 of predators/LD50 of insect pests. Among four carbamates, carbaryl was least toxic to L. pseudoannulata and C. maculatus. Of the organophosphates used, fenitrothion, pyridafention and tetrachlorvinphos were less toxic to L. pseudoannulata but were highly toxic to C. maculatus. C. maculatus, however, was very susceptible to six organophosphates. The toxicity of chlorophenamidine to L. pseudoannulata was as high as carbamates but was low to C. maculatus. The acute toxicity of cartap to L. pseudoannulata was low, i.e., 102.6 μg/g(LD50 after 24 hr), but all spiders were paralysed as low as at 10 μg/g and their recovery was postponed 8 days. The toxity of γ-BHC and methomyl to both species of predators were high : the values of the relative toxicity were far less than unity.

The production of a major component, 6-oxo-1-nonanol and a minor compound, N-3-methylbutyl acetamide in the male rectal gland of Bactrocera carambolae, a fruit pest of economic importance, increased concomitant with age, and their peak production corresponded with sexual maturity. During courtship period, these endogenous components were released unchanged into the air as visible smoke by a group of 100–150 males in a glass chamber. Male emissions elicited upwind flight via zigzag anemotaxis, and attracted more conspecific virgin females than males in wind tunnel assays. When these components were assayed individually, both 6-oxo-1-nonanol and N-3-methylbutyl acetamide elicited significant female responses toward the source chemicals, although the response was less than that for live males. The results suggested that these volatile components are involved in the intraspecific communication by playing a role as sex pheromones during courtship of B. carambolae.

The distribution and food habit of the flatworm species Platydemus manokwari, which is known to be a predator of land snails, were examined on Chichijima Island of the Ogasawara (Bonin) Islands, Japan. P. manokwari was distributed over a wide area of the island. Few live land snails were found in the area where P. manokwari was distributed. Further, it was revealed that P. manokwari fed not only on live land snails including predatory species, but also on other food resources such as live flatworms or a land nemertean species and the carcasses of slugs and earthworms. Therefore, P. manokwari is expected to survive even if the populations of land snails are almost lost on Chichijima Island in the future, and so will affect the biodiversity of Chichijima Island.

Snails of the genus Pomacea in several regions of Japan showed genetic divergence. Phylogenetic analysis based on the mitochondrial cytochrome c oxidase subunit I gene segregated them into two major clades, one corresponding to P. insularum, the other to P. canaliculata. We developed a simple molecular method to distinguish between the two species to investigate their distribution in Japan. We identified P. canaliculata at all 16 sampling locations except Iriomote Isle, and P. insularum at four locations (Iwata, Fukuyama, Ishigaki Isle, and Iriomote Isle), supporting a previous report that P. canaliculata is the dominant species in Japan. Morphological comparison of the two species collected from the same habitat (Ishigaki Isle) revealed that most P. canaliculata had clear dark spiral bands on their shells, and that P. insularum had no or only faint spiral bands. However, it is difficult to distinguish the two species using only shell morphology.

Existence of alarm pheromone in stink bugs was demonstrated. The secnt discharged from the stink bugs for the purpose of defense against their enemies, made the other individuals of the same species alert and disperse. trans-2-Hexenal, one of the majnor components of the scent, had the same alarm effect. The activity was not species-specific among at least three species of Pentatomid bugs, Eurydema rugosa, E. pulchra and Nezara viridula.

Aggregate formation of the 1st instar larvae of Eurydema rugosa was induced by both olfactory and tactile responses rather than visual perception. The chemical stimuli responsible for the aggregation were derived from scent components produced by the stink bugs themselves. These chemical substances were considered as "aggregation pheromone." trans-2-Hexenal, one of the major components of the scent of E. rugosa, had roles of "attractant" and "arrestant". The same aldehyde was reported to have an alarm effect for aggregating larvae of R. rugosa (ISHIWATARI, 1974), therefore, trans-2-hexenal was considered to be not only the alarm pheromone component but also the aggregation pheromone component.

Host-use pattern for overwintering and reproduction of the ragweed beetle, Ophraella communa LeSage, was examined in Tsukuba, Japan. Many adults of both sexes were found overwintering inside the rolled parts of dead leaves of Xanthium canadense in November. These adults had already accumulated triacylglycerol as energy reserves, and were able to survive the winter and to reproduce in the spring. No eggs and larvae were found on X. canadense throughout the observation period, although overwintered adults were temporarily found in May. In contrast, reproduction occurs on Ambrosia artemisiifolia and A. trifida in late April. These results suggest that O. communa adults mainly use dead leaves of X. canadense as an overwintering shelter in Tsukuba, while they reproduce only on A. artemisiifolia and A. trifida in the spring. Such a seasonal migration between host plants may be important for the survival strategy.

Buzz-pollination of tomato (Lycopersicon esculentum MILL) by four native species of Japanese bumblebees (Bombus hypocrita hypocrita PEREZ, B. ignitus SMITH, B. ardens ardens SMITH, and B. diversus diversus SMITH) was examined. A high (84-100%) fruiting rate and almost no puffy fruit )0-7%) resulted from pollination by the Japanese bumblebees. There was no difference in the pollination efficiency between the imported non-native bumblebee (B. terrestris) and Japanese bumblebees. Pollination of tomato crops using native bumblebees is recommended because there are no ecological risks.

We investigated the inheritance of cannibalistic behavior in larvae of the common cutworm, Spodoptera litura. The fact that artificial selection of non-cannibalistic animals over 17 generations resulted in decrease of their cannibalistic behavior is clearly the proof of their inheritance of this behavior. Average frequency of cannibalism in selected larvae (3.2%) was significantly lower than that in non-selected larvae (24.5%). We employed the differential display RT-PCR analysis to evaluate differences in gene expression in the brains between selected and non-selected lines, and identified one gene whose expression was significantly higher in non-selected line larvae than that in selected line larvae. The identified gene with 779 bp was a novel gene without a major sequence homology with any reported genes. This gene was expressed in several tissues, fat body, brain, and hemocytes, among which the highest expression was observed in the brain. Further, the expression of this gene was very low in the brain of normally fed larvae but starvation significantly enhanced its expression only in the non-selected larvae. These results imply the possibility that the gene identified in the present study contributes to initiating cannibalistic behavior of S. litura larvae although the detailed function of this gene is unknown at present.
