TL;DR: A new stem-miner of alder in Japan is described, and a review of the larval transformation in the Gracillariidae (Lepidoptera) is reviewed, with notes on the origin and significance of the peculiar larvae of the sap-feeding, spinning and quiescent forms.
Abstract: KUMATA, T. 1978. A new stem-miner of alder in Japan, with a review of the larval transformation in the Gracillariidae (Lepidoptera). Ins. matsum. n.s. 13: 1-27, 8 figs. (6 textfigs., 2 pIs.). Dendrorycter marmaroides (n.g., n. sp.), a stem-miner of alder in Japan, is described. Its peculiar heteromorphic development in the larval stage is described, and the heterometamorphosis in the family Gracillariidae is reviewed. The larvae of the family are divided into 4 forms based on the structure and function: sap-feeding, tissue-feeding, spinning and quiescent forms. The patterns of the ontogenetic life-cycle are compared in 11 species belonging to 10 genera. The evolutionary trends of the family are discussed on the basis of the comparison, with notes on the origin and significance of the peculiar larvae of the sap-feeding, spinning and quiescent forms. A uthoy' s address. Entomological Institute, Faculty of Agriculture, Hokkaido University, Sapporo, 060 Japan.

TL;DR: The present review will be concerned more specifically with structure and chemistry, the infection process, quantitative virus-host relationships and the natural occurrence of viruses in their host populations.
Abstract: The best known insect viruses cause the formation of inclusions in the cells they infect. They were first observed in the mid-nineteenth century and since then have received considerable attention from entomologists and microbiologists. In recent years, several authors have reviewed studies on this group of viruses (Bergold, 1958; Aizawa, 1963; Smith, 1963; Huger, 1963) and the present review will be concerned more specifically with structure and chemistry, the infection process, quantitative virus-host relationships and the natural occurrence of viruses in their host populations. The nuclear-polyhedroses of Lepidoptera and Hymenoptera (Sawflies), the cytoplasmic polyhedroses of Lepidoptera and the granuloses of Lepidoptera are discussed in detail.
