Phoretic association between the egg parasitoid Protelenomus sp. and the coreid bug Anoplocnemis phasiana was studied on Ishigaki-jima Island, Japan. The egg parasitoids were associated only with adult bugs. The parasitoids were found on 28.7% of female bugs and on 20.0% of male bugs, and there was no significant difference in the frequency between female and male bugs. The mean and maximum numbers of parasitoids on a bug were 1.2 and 24 for female bugs, and 0.6 and 14 for male bugs, respectively. The number of parasitoids attached to a bug sometimes exceeded the number of eggs in a batch of host bugs. The parasitoids exhibited clumped distribution among the bugs. Most parasitoids were found on the hind femora in male bugs, while about half of parasitoids were attached to the antennae in female bugs. The transfer of parasitoids from a male bug to a female bug was observed to occur while the bugs were copulating. Therefore, phoresy on male bugs is not always disadvantageous for the egg parasitoid. Since the bugs change their host plant seasonally, phoresy on male bugs can be advantageous if the bugs are used as vehicles for transportation to distant places according to the host plant changes of the host bugs.

We investigated the prey-predator relationship between aposematic pyrrhocorid bugs, Antilochus coqueberti and Dysdercus cingulatus. They are similar in appearance and often found in the same habitat simultaneously. Carnivory of A. coqueberti on D. cingulatus and D. decussatus was observed in the field, and A. coqueberti could not develop when experimentally fed on only plant materials, strongly indicating the obligate carnivory of A. coqueberti. While A. coqueberti did not prey on bugs in the families Lygaeidae, Largidae, Coreidae, and Rhopalidae that share the aposematic body coloration with A. coqueberti and D. cingulatus, A. coqueberti preyed on all the pyrrhocorids and alydids provided, regardless of their body coloration. Visual resemblance is only partially involved in the prey preference of A. coqueberti. We conclude that A. coqueberti is the obligate predator specialized to Dysdercus species.

Eggs, final instar larvae, and pupae (male and female) of Bibio tenebrosus Coquillett, B. holomaurus Hardy & Takahashi, B. adjunctus Hardy & Takahashi are described. Except for the larva and pupa of B. tenebrosus, this is the first description of the immature stages of these species. On the basis of careful examination of the head structure, the following characters are suggested to be useful for distinguishing Bibio species : the shape of the cranium, the arrangement of the six sensory pits on the frontal apotome, and the structure of the epipharynx, prementum, and dorsal surface of the stipes. Brief ecological information is also given for each species, and notable morphology of the bibionid larvae and diagnostic characters of the immature stages of Bibio are discussed.

To examine the species integrity of a water strider, Gerris gracilicornis, multivariate analyses based on 32 morphometric characters were performed on 158 male adults collected from 47 populations in the Russian Far East, Korea, Taiwan, and Japan, as well as on 66 individuals of three other Gerris (Macrogerris) species (G. yezoensis, G. insularis, and Gerris sp.). In canonical discriminant analyses, all of these species were distinguished unambiguously. When multivariate analyses were applied to G. gracilicornis individuals, both principal component and canonical discriminant analyses indicated that there are three morphologically and geographically separated population groups (Groups A, B, and C). Group A is distributed in the Korean Peninsula and the Japanese Islands from Hokkaido Island to Yaku-shima Island, Group B in the Ryukyu Islands from Amami-oshima Island to Yonaguni-jima Island, and Group C in the Russian Far East, Cheju Island of Korea, and Taiwan. Canonical discriminant analysis of laboratory-grown insects suggested that the morphometric differences among these groups were not due to environmental or climatic differences, but to genetic differences among the different groups.

Sturmia micronychia sp. nov. is described from Japan. This species is very similar to S. bella (Meigen) and both are reared from the chestnut tiger butterfly, Parantica sita niphonica (Moore), and a papilionid, Byasa alcinous (Klug), in Japan. The male genitalia of both species are illustrated and diagnostic characters are given. A key to Asian species of Sturmia is provided and known species of the genus from Asia and Oceania are briefly redescribed.

Nucleotide sequences of a 0.7kb portion of the mitochondrial cytochrome b gene were analyzed using Japanese species of water striders belonging to the subgenus Macrogerris. Although the sequences were rather homogeneous among individuals within both Gerris gracilicornis and G. yezoensis, considerable variation was observed among insects showing conventionally recognized diagnostic characteristics of G. insularis. Results of molecular phylogenetic analyses clearly indicated that there are three distinct lineages, designated as types A, B, and C, among these latter insects. Comparisons of nucleotide sequences indicated that genetic distances among these lineages were much larger than those between G. gracilicornis and G. yezoensis. From PCR-RFLP analyses of insects collected from 35 localities, it was revealed that the geographic distributions of types B and C were divided between northeastern Honshu island and western Japan including Kyushu island and central to western Honshu island, whereas that of type A largely overlapped with those of the other two types. Although male adults of the three types were homogeneous in conventionally recognized diagnostic characteristics, apparent differences were observed in the shape of the head, pronotum, fore femur, and color pattern of the anterior pronotum between type A and the other two types. In addition, types B and C showed apparent dimorphism in hind wings, containing both long- and short-winged individuals, whereas type A showed only long and wide hind wings. Preliminary observations of mating behavior indicated that a precopulatory reproductive isolation is operative between type A and other two types. Based on these results, evolutionary relationships among the three lineages are discussed.

The Old World genus Oidanothrips Moulton comprises large macropterous thrips, which have the head long and dorsally elevated and the maxillary stylets broad and often extremely long with one lateral loop or more. Despite the broad stylets, the genus is placed in the Docessissopho-thrips-lineage of the subfamily Phlaeothripinae. The genus is here revised and a key provided to 11 included species, of which 7 are described as new : O. malayensis sp. n., O. maxillatus sp. n. and O. moundi sp. n. from West Malaysia ; O. taiwanus sp. n. and O. takasago sp. n. from Taiwan ; O. nigripes sp. n. from the Ryukyu Islands, Japan ; and O. sumatrensis sp. n. from Sumatra, Indonesia.

Catotricha is a species-poor, relict group of ancient gall midges (Cecidomyiidae), formerly classified in the subfamily Lestremiinae. It is here excluded from the Lestremiinae and given subfamily rank of its own. The Catotrichinae subfam. n. are sister group of the remainder of the Cecidomyiidae, Lestremiinae s. str.+(Porricondylinae+Cecidomyiinae). The Lestremiinae in this new, strict sense are shown to be monophyletic, justified by a pecularity of their antennae. Details of the antennae, palpi and thorax in Catotricha are discussed phylogenetically and with consideration of homologous structures in other Mycetophiliformia. Catotricha fraterna sp. n. from Australia is described. Catotricha nipponensis (Alexander, 1924) from Japan is redescribed ; Catotricha antennata Alexander, 1959 is considered a junior synonym of nipponensis.

Records of specimens suggesting cleptoparasitism of Poecilagenia sculpturata (Kohl) on Auplopus carbonarius (Scopoli) are reviewed, and the cleptoparasitic behavior of this species is described. In her searching behavior, female P. sculpturata repeatedly uses the antennae by applying them to the substrate near where other pompilids are nesting. The flagellar sensilla of this species are observed by SEM, and the following types of sensilla are found : sensilla placodea, sensilla basiconica A, pit organs, sensilla campaniformia, sensilla trichodea A, B, C, and sensilla spatulata. The structure of the antenna and sensilla of P. sculpturata is compared with that of A. carbonarius. The female P. sculpturata has a shorter and stouter fusiform flagellum with denser sensilla basiconica A on its anteroventral side. Similar structures are found in cleptoparasitic pompilids, Evagetes species. These structures are considered to have evolved due to convergence as an adaption to the cleptoparasitic mode of life. The sensilla basiconica A are presumed to play the most important role in locating the host or paralyzed spider.

To elucidate the diapause pattern of Lepisma saccharina Linnaeus, strains collected in Hirosaki were kept under controlled conditions of photoperiod and temperature. The interval between moults was uniformly short in the first two instars, but tended to increase in the later instars and showed a very large variation owing to the occurrence of diapause in some individuals but not in others. When reared at 25℃, this insect started oviposition in the 9th or 10th instar but thereafter continued to grow and moult. Some individuals survived 2.5 years or more and moulted more than 30 times. The incidence of diapause as defined by the instar duration of longer than 50 days was affected by temperature, photoperiod and age. The duration of diapause was highly variable among individuals, lasting more than 180 days at 25℃ in extreme cases. Diapause may occur in any larval and adult instar but not in the first two instars, and may be repeated in separate or consecutive instars. Some individuals underwent 8-9 diapause instars in 600-800 days. At 20℃, diapause occurred in the younger (3rd and 4th) instars at a higher frequency, and a photoperiodic response of the long-day type was manifested more clearly, than at 25℃. A high temperature of 28℃ prevented diapause at least in the larval stage under both short (12h) and long (16h) photoperiods.

Field observations showed that the gall-parasitic flea weevil Rhynchaenus hustachei often parasitized the pouch galls of the aphid Paracolopha morrisoni on Zelkova serrata leaves in the Kinki District, Central Japan. The eggs of the weevil were laid into the gall walls and hatched larvae entered the galls. Each parasitized gall contained only one weevil. The inside of the gall wall was heavily grazed by the weevil larva, resulting in destruction of the aphid colony. These observations suggest that the weevil is an obligatory cecidophage. At three of six study sites, weevil parasitism was the greatest mortality factor for the aphids. A facultative hyperparasitoid, Eupelmus urozonus (Eupelmidae) and Pteromalus sp. (Pteromalidae) parasitized the larvae and pupae of the weevil.

Mepleres suzukii (Okamoto, 1910) (Psocoptera: Pseudocaeciliidae) was redescribed. Mepleres Enderlein, 1926 had been incorrectly treated by some authors as an invalid synonym of Pseudoscottiella Badonnel, 1946. Thus, Pseudoscottiella was appropriately treated here as a junior synonym of Mepleres. Meniscopsocus Li, 1993 was newly synonymized with Mepleres. All new species combinations resulting from these taxonomic treatments were listed. Within Mepleres, African and Oriental-Pacific-Australian species groups had been recognized, with Mep. suzukii assigned to the latter group. However, monophyly of the latter group could not be justified, whereas the African group was regarded as monophyletic. A key to Japanese Mepleres was provided.

Community patterns of early spring moths in four secondary forests of Kyoto were studied by molasses trapping with special reference to the vegetation. A total of 1086 individuals belonging to 27 species of Hadeninae, Cuculliinae (Noctuidae), and Thyatiridae were caught in 1993-1995. Orthosia spp., Agrochola evelina, and thyatirids were abundant in woodland with predominant deciduous Quercus trees, while Rhynchaglaea spp. were abundant in woodland dominated by evergreen oaks. The effectiveness of the molasses traps increased with rising air temperature, but declined after April. To survey early spring moths using molasses traps, the season and air temperature should be checked.

We examined the salinity tolerance of a small aquatic beetle species, Hygrotus impressopunctatus (Dytiscidae), collected from the Kuril Islands. All beetles in seawater died by the 13th day, and 21 out of 54 beetles were still alive in freshwater on the 13th day. One beetle survived in seawater for at least 12 days. Over 50% of the beetles survived the first four days in seawater, and their survival was almost the same as those in freshwater. The mean survival time of the beetles in seawater was 6.2 days. This study suggests that H. impressopunctatus could disperse via seawater, although their survival was significantly better in freshwater.

Multiple-cavity galls of a cerataphidine species were found on the evergreen Styrax benzoides in Chiang Mai, northern Thailand. Comparison of mitochondrial DNA sequences between aphids from the galls and aphids of Pseudoregma carolinensis from bamboo revealed that the gall-forming aphids are of P. carolinensis. The colony sizes of mature galls were comparatively small, up to approximately 1, 500 individuals. The galls contained many pseudoscorpion-like 2nd-instar soldiers, which attacked an experimentally introduced moth larva, and which were observed to push globules of honeydew out of the subgall. The life cycle (holocycle) is probably annual, with some aphids remaining on bamboo throughout the year. The gall and alate morph are described.
