ネマルハキバガ科はキバガ上科の中でも最も分類が困難なグループの一つであり，寄主の記録がある種は既知種の10％以下に限られる．我々は鹿児島県の温室においてウンシュウミカン Citrus unshiu (Swingle) Marcowicz の早期落果を引き起こした小蛾5個体を精査し，うち4個体が日本未記録のイナーナネマルハキバガ（新称） Lateantenna inana (Butler, 1881) n. comb.，残りの1個体がウスオビネマルハキバガ L. decolor (Meyrick, 1907) であることをDNAバーコーディングと成虫形態から確認した．また，広島県においてカキノキ Diospyros kaki Thunberg の樹皮下から得られた小型蛾類の飼育により，L. decolor がカキノキの形成層も摂食することを確認した．さらに本論文では，L. inana に加えて，Lateantenna scotia Turner, 1947 n. comb. も Blastobasis Zeller, 1855 から Lateantenna Amsel, 1968 へと属の移動を行った．

Yoshida A. . Coherent array of branched filamentary scales along the wing margin of a small moth . Science of Nature104 ( 3-4 ) 27 2017.4Invited Reviewed

Language：English Publishing type：Research paper (scientific journal) Publisher：Science of Nature

In butterflies and moths, the wing margins are
fringed with specialized scales that are typically longer than common scales. In the hindwings of some small moths, the posterior margins are fringed with particularly long filamentary scales. Despite the small size of these moth wings, these scales are much longer than those of large moths and butterflies. In the current study, photography of the tethered flight of a small moth, Phthorimaea operculella, revealed a wide array composed of a large number of long filamentary scales. This array did not become disheveled in flight, maintaining a coherent sheet-like structure during wingbeat. Examination of the mor-
phology of individual scales revealed that each filamentary scale consists of a proximal stalk and distal branches. Moreover, not only long scales but also shorter scales of various lengths were found to coexist in each small section of the wing margin. Scale branches were ubiquitously and densely distributed within the scale array to form a mesh-like architecture similar to a nonwoven fabric. We propose that possible mechanical interactions among branched filamentary scales, mediated by these branches, may contribute to maintaining a coherent sheet-like structure of the scale array during wingbeat.

The whitefly Bemisia tabaci （Gennadius） is an important economic pest, being a vector of Tomato yellow leaf curl virus （TYLCV）. In this study, we evaluated the inhibitory effect of two insecticides on TYLCV transmission by whiteflies. Tomato plants pretreated with pyrifluquinazon or dinotefuran （0 and 7 days before inoculation） were significantly less infected with TYLCV than untreated plants, while plants pretreated 14 day before inoculation did not show any difference. In contrast, the survival rates of viruliferous whitefly on pretreated plants 0, 7, 14 days before inoculation were significantly lower than those on untreated plants. These results indicate that sprays of these insecticides at 7-day intervals were effective in inhibiting the incidence of TYLCV transmission by whiteflies.

Spatio-epidemiological and Risk Analysis of Factors Leading to the Establishment of an Invading Population of the West Indian Sweet Potato Weevil in Ibusuki City, Kagoshima Prefecture, Japan . Japanese Journal of Applied Entomology and Zoology58 ( 3 ) 237 - 247 2014International coauthorship

The West Indian sweet potato weevil, Euscepes postfasciatus Fairmaire, was distributed only on Nansei and Ogasawara (Bonin) Islands in Japan until 2008, when the weevil was found for the first time in Ibusuki City, which previously regarded as a weevil-free area. In this study, we used epidemiological approaches to determine how the weevil population in Ibusuki City was established. We conducted spatial distribution analysis and case–control studies based on survey data gathered from 270 farmers who cultivated sweet potato in 2008. Weevils were present at 46 sweet potato (Ipomoea batatas) cultivation sites and four blue morning glory (Ipomoea indica) growing sites. The weevil infestation rate was higher in sweet potato plants than in wild host plants. Weevil infestation was strongly associated with the use of tuber trench silo storage (odds ratio, 4.45). The association with silo storage suggested that the tuber storage silos provided an overwintering refuge for the weevil. The case–control study also revealed that cultivation without pesticides and for home use were associated with weevil infestation. Activities such as the transfer of tubers or leaving tubers in the field may expand the distribution of the weevil population over a wider area.

To explore new characteristics never previously used diagnostically in certain insect groups, we analyzed female genital shapes in four species of egg parasitoid wasps, Trichogramma (Hymenoptera, Trichogrammatidae), by using elliptic Fourier descriptors. Species of this genus have hitherto been identified solely on the basis of male genitalia. Thus, we tried to distinguish four species of Trichogramma from each other using only female characteristics. Although principal component analysis of the standardized Fourier coefficients obtained from the contours of the female genitalia revealed complete isolation of T. japonicum from the other three examined species, the first and second principal component score distributions of T. chilonis, T. dendrolimi, and T. papilionis overlapped. Nevertheless, these three species could be differentiated each other by canonical discriminant analysis of the coefficients. Redrawn contours along the axes of canonical variables showed that interspecific shape differences of female genitalia were more subtle than intraspecific ones. A series of such analyses represents a good example of how elliptic Fourier descriptors can be used in taxonomic studies.

Recent developments in geometric morphometrics enable us to precisely examine morphological variations in the shape and size of organisms, including insect species. We review modern well-established morphometric approaches frequently used in entomology. Three non-mutually exclusive technical morphometrics methods are briefly explained: 1) multivariate morphometrics, 2) superimposition and thin-plate spline analysis, and 3) outline analysis. The latter two approaches are generally referred to as geometric morphometrics. We then review recent literature relevant to geometric morphometrics and consider the application of these approaches in the context of systematic and evolutionary studies of insects.
