Adult feeding affects fecundity of the predator,Calosoma sycophanta (Col.: Carabidae)
Entomophaga, 1993Calosoma sycophanta L. adults were fed either gypsy moth (Lymantria dispar L.) larvae or split grapes for set periods of time while their reproduction was monitored. Few female beetles reproduced unless fed gypsy moth larvae during the first week after they ended hibernation.

Environmental Entomology, 1985
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

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 ...

Approximately 100 Calosoma sycophanta L. adults were released in each of 5 plots located near the leading edge of gypsy moth, Lymantria dispar (L.), expansion in Delaware, Michigan, and West Virginia. Before release, naturally occurring beetle populations were present in West Virginia, but not in the other states.

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 ...

Emigration and spatial dispersion of the gypsy moth predator Calosoma sycophanta
Entomologia Experimentalis et Applicata, 1987AbstractMark‐release studies of Calosoma sycophanta L. (Carabidae) in two 40000 m2 areas were done using traps deployed in 10 by 10 grids. In both areas, gypsy moths, Lymantria dispar L. (Lymantriidae), were abundant the first but not the second year of sampling.

Experimental Forest Releases of Calosoma sycophanta (Coleoptera: Carabidae) Against the Gypsy Moth
Journal of Economic Entomology, 1990Releases of limited numbers of Ca/osoma sycophanta L. adults into high populations of gypsy moths, Lymantria dispar L., were made in 1988 and 1989. In 1988, 0-40 wing-clipped beetle adults were released into four plots. Larval survival of gypsy moths was least in plots receiving the most beetles, but based on gypsy moth pupal mortality and numbers of ...

The Canadian Entomologist, 1997
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.
