Diapause intensity (DI) is a physiological trait represented by the duration of diapause under given conditions of environment. In many species, it is highly variable, probably being controlled by multiple genes and tends to form a cline in response

The ground cricket Dianemobius nigrofasciatus overwinters as an egg in Japan, being univoltine in Hokkaido and northern Honshu and bivoltine farther south. In Hokkaido, however, this cricket is heard singing in winter in several fumarolic fields cove

. Locomotor activity rhythms were studied in eight species of nemobiine crickets with different habitat preferences. They showed similar patterns with a major peak of activity around dusk and a minor one around dawn. These patterns did not change wit

Loss of functional hindwings is observed in most subfamilies of Japanese crickets. Habitat, behaviour, body size and phylogenetic factors might be involved, but interactions among them may obscure the general trend. Wing dimorphism is common among th

Dianemobius fascipes is a wing-dimorphic cricket, developing long wings under long-day and crowded conditions at 28°C. Even under these conditions, however, severance of appendages in the nymphal stage exerted a micropterizing effect. A similar, tho

Both oscillator and hourglass features are found in the photoperiodic response that controls the pupal winter diapause of Mamestra brassicae. The expression of oscillatory response to extended long-night cycles is temperature dependent, i.e. circadia

In the cabbage moth, Mamestra brassicae, the type of pupal development (winter diapause, summer diapause or non-diapause) is detrmined by photoperiod in the larval stage. Interacting effects of photophase and scotophase were examined by exposing larv

Egg diapause in the Nara (temperate, 34° 40'N) strain of Dianemobius nigrofasciatus of the D. fascipes species‐complex is programmed by the parental photoperiod and expressed as delayed hatching at a high temperature (25°C). However, very few del
