Weed control by insects is increasingly important, as chemical weed control (the use of herbicides) has an important impact on the environment and, consequently, on all organisms living there. The use of insects to control weeds thus represents an alternative to herbicides. The article presents the suppression of some widespread and persistent weeds in Europe with their natural enemies - insects. The following combinations presented below are: broad-leaved dock (<em>Rumex obtusifolius</em> L.) – <em>Gastrophysa viridula</em> (De Geer, 1775), curly dock (<em>Rumex crispus</em> L.) – <em>Apion violaceum</em> (Kirby, 1808), common ragweed (<em>Ambrosia artemisiifolia</em> L.) – <em>Ophraella communa</em> (LeSage, 1986) and <em>Zygogramma suturalis</em> (Fabricius, 1775), creeping thistle (<em>Cirsium arvense</em> (L.) Scop.) – <em>Cassida rubiginosa</em> (Müller, 1776), cleavers (<em>Galium aparine</em> L.) – <em>Halidamia affinis</em> (Fallen, 1807) and <em>Sermylassa halensis</em> (Linnaeus, 1767), common knotgrass (<em>Polygonum aviculare</em> L.) and black-bindweed (<em>Fallopia convolvulus</em> L.) – <em>Gastrophysa polygoni</em> (Linnaeus, 1758) and as the last one field bindweed (<em>Convolvulus arvensis</em> L.) – <em>Galeruca rufa</em>  (Germar, 1824) and <em>Tyta luctuosa</em> (Denis in Schiffmuller, 1775).

AbstractThe critical photoperiod for diapause induction in pupae of Mamestra configurata Walker in Manitoba was 16 h 06 min at Glenlea (49°38′ N), 16 h 20 min at Grandview (51°10′ N), and 16 h 42 min at Birch River (52°24′ N). The differences in cirtical photoperiods observed at Glenlea and Grandview were not significant. At least two different photoperiods exist, one in the Glenlea and Grandview areas and the other in the Birch River area. In the laboratory, the critical photoperiod was 13.5 h when larvae were exposed to a daily fluctuating temperature regime of 12 h at 25 °C and 12 h at 10 °C. Longer critical photoperiods found for the field populations may be related to the relatively low ambient temperatures to which the larvae were exposed in field cages.

Archytas marmoratus (Townsend) was reared on corn earworm, Helicoverpa zea (Boddie), or fall armyworm, Spodoptera frugiperda (J. E. Smith). Rearing chambers were programmed for a constant temperature of 15, 16, 19, 20, 22, 24, or 25°C and a photoperiod of 10:14 h (L:D) or 25°C and a photoperiod of 12:12 h (L:D). Development of parasitoids was faster when corn earworm larvae were parasitized than when fall armyworm larvae were parasitized. At 15°C parasitoid survival was poor on both hosts but at 16°C, more parasitoids eclosed on corn earworm than fall armyworm. Diapause induction in this strain of corn earworm was low. All pupae that eclosed after being in diapause produced an adult corn earworm. The data suggested that A. marmoratus is not influenced by diapause induction in its host but continues to develop above the threshold temperature for survival. This would restrict its overwintering as a larva or pupa to regions that have a continuous, nondiapausing host population. Thus, yearly establishment of A. marmoratus in more temperate areas would be required.
