ItemDescription of Hamakua Pamakani Plume Moth from Hawaii (Lepidoptera: Pterophoridae)(Hawaiian Entomological Society, 1983)A new plume moth, Oidaematophorus beneficus n. sp., is described and figured. This plume moth has been introduced from Mexico to control a weed, Ageratina riparia (Regel) K. & R., known as Hamakua pamakani in Hawaii. This is the first record of the genus from Hawaii.

ItemSpatial Distribution of the Migrants of the Corn Delphacid, Peregrinus maidis (Ashmead) (Homoptera: Delphacidae) in Cornfields(Hawaiian Entomological Society, 1983)Spatial distribution of the migrants of the corn delphacid in plantings of corn used for silage was determined by sampling population density at sites throughout fields. By this means, migrants were found to aggregate along borders of fields. There were variations to this pattern, but the same borders were generally infested in successive plantings of the same field. Within each field, population density decreased continuously with distance from the borders. This decline was shown to be described by the relationship log(m) = log(a)+bx, where m is the average number of migrants per plant at distance, x (in meters), from the edge, and a is the average per plant at the field edge. Calculation of b, the regression coefficient, and use of this information in pest surveillance are described.

ItemThe Biology, Host Range, Parasites, and Hyperparasites of Koa Seed Insects in Hawaii: a Review(Hawaiian Entomological Society, 1983)The biology and host range of koa seed insects, their parasites, and hyperparasites in Hawaii are reviewed. The information reported may be applicable to other native or introduced legumes because of the wide host range of a few of the insects.
