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 ...

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

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 ...

Field Observations on the Flight Activity of Calosoma sycophanta (Coleoptera: Carabidae)
Annals of the Entomological Society of America, 1971The importance of Calosoma sycophanta L., as a predator of caterpillars has been recognized for many years. The extensive outbreaks of gypsy moth, Porthetria dispar (L.), and browntail moth, Nygmia phaeorrhoea (Donovan) in New England during the early 1900's initiated concerted efforts to establish C. sycophanta in that area.

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.

Rearing the Cannibalistic Larvae of Calosoma sycophanta (Coleoptera: Carabidae) in Groups
Journal of Entomological Science, 1996Cannibalistic immatures of the gypsy moth (Lymantria dispar L. [Lepidoptera: Lymantriidae]) predator Calosoma sycophanta L. (Coleoptera: Carabidae) must usually be reared individually. This paper describes a method of rearing C. sycophanta larvae in groups by placing them in plastic containers having 3 cm of moist peat moss in the bottom.

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.
