Silkworms have been found cross infected with other microsporidia of insects in mulberry trees, forest and fruit gardens. Even the unidentified microsporidian species were not seriously pathogenic to silkworms, the silkworm egg producers lose their profit because of the elimination of eggs laid from moths which are infected with any kind of microsporidian species. Recently, the microsporidian cross infection to silkworm is in tendency of increase and the authors have investigated the field insects to examine the microsporidia. The number of species of insects infected with microsporidia was 10 and they were Boellcherisca peregrina (Rebineau-Desvoidy), Apis melifera Linnacus, Artogenia rapae Linnacus, Tipula aino Alexander, Altica caeruleseens (Baly), Anomela daimiana Harold, Eilema griseola (Hubner), Rbalbistylun speciosum Uller, Anisodactylus signatus Illiger, Oulema oryzae (Kuwayama). From the Boettcherisca peregrina (Robineau-Desvoidy), three different species of microsporidia were isolated and the microsporidia isolated from Boettcherisca peregrina (Robineau-Desvoidy), Apis melifera Linnacus, Artogenia rapae Linnacus donot have infectivity to inflectivity to silkworm larvae, Bombyx mori L.

This study analyzes the factors affecting the adoption rate of electric vehicles. It utilizes a panel fixed effects model with the electric vehicle registration ratio as the dependent variable and local government purchase subsidies, the number of chargers, and exemption from mandatory bond purchases as independent variables, while national purchase subsidies, electricity rates, battery energy density and price, and average winter temperature are controlled for. The analysis showed that while local government subsidies and charger installation policies did not significantly impact the expansion of electric vehicle adoption, exemption from mandatory bond purchases did have a significant effect. The average winter temperature also significantly affected the adoption rate of electric vehicles, suggesting that local governments should consider this when making related policies. On the other hand, national purchase subsidies, battery energy density, and battery price were found to significantly influence the expansion of electric vehicle adoption. Given that national subsidies are decided considering battery energy density or price, this implies that subsidies should be maintained at a certain level until battery performance improves. Electricity rates also had a significant impact on the adoption of electric vehicles, indicating that additional policies to reduce operating costs, such as electricity rate discounts, are needed to encourage the expansion of electric vehicle adoption
