Environmental Entomology, 1998
The effect of prey type and abundance on the reproductive success and pre-ovipositional activity of the ground beetle Calosoma sycophanta L. was investigated to better understand their relationship with the gypsy moth, Lymantria dispar (L.). We obtained the numbers of ovipositing females, eggs per oviposition, and viable eggs for beetle pairs fed ...

Journal of Entomological Science, 1998
A newly-developed larval diet for Calosoma sycophanta L. consists of beef liver and chicken meat. Larvae reared individually on this diet develop at about the same rate and have the same survival as those fed gypsy moth pupae, Lymantria dispar L., the usual prey of the beetle. However, adults of diet-reared larvae were significantly smaller than adults

Calosoma sycophanta L.(Col., Carabid.) andNabis apterus F.(Hemipt., Nabid.) were observed attacking and feeding onLymantria monacha, Bupalus piniarus andDiprion spec.-larvae and pupae in some pine stands in southern and northern Bavaria 1965. It is intended to investigate the two species in regard to their biology and importance for biological control ...

Environmental Entomology, 1989
Three models (linear, third-degree polynomial, and one based on enzyme kinetics) were used to simulate the dependence of Calosoma sycophanta L. developmental rate on temperature. In conjunction with a model of individual differences in development based on the Weibull distribution, the models were used to predict development of C.

AbstractVisual responses of adults ofCalosoma sycophantaL., which are predators of the gypsy moth,Lymantria disparL. (Lepidoptera: Lymantriidae), were investigated in laboratory arenas. Beetles moved toward dark cylinders significantly faster than to light ones when the background was white, but no differently when the background was black.

AbstractIn feeding choice tests, first- and second-instar larvae of Calosoma sycophanta L. preferred gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae), pupae as prey but third-instar larvae most often consumed caterpillars. All beetle larvae preferred female pupae over male pupae.

AbstractAdult Calosoma sycophanta L. (Carabidae: Coleoptera) male and female pairs in a laboratory arena were observed for up to 30 days with a video recorder. Beetles were visible (i.e. not hiding) or in soil (i.e. female ovipositing) especially during night hours. Feeding on gypsy moth larvae occurred any time of the day or night.

Environmental Entomology, 1989
Two-dimensional spectral analysis is used to highlight periodiCities in regular lattice samples of insect spatial distributions. The technique is explained, and simulated distributions are analyzed to show how results are interpreted. Based on analyses of samples at one site, the distributions of gypsy moth larvae are characterized by wavelike ...

In 1983 and 1984 I studied the gypsy moth, Lymantria dispar (L.), predator, Calosoma sycophanta L., in a collapsing gypsy moth infestation. Beetles caught in tree-trunk barrier traps were marked and released to assess the directions and distances they dispersed and their population sizes. In both years, about 700 to 1,000 adult beetles of each sex were
