| Abstract: | A collection of carabids or ground beetles of 106 species belonging to 21 genera was made in the farmlands of Heilongjiang-from 1980 to 1982. Some 48 species were coll-ected by means of pitfall traps. 12 species and their distribution in the standing crop lands are listed and the dominant species are Pterostichus nitidicollis Motsehulsky, P. sp., P. cliinensis Jedlicka, Chlaenius pallipes Gebler and Campalita chinense Kirby. These species were found to prey on 12 to 17 species of insect pests infesting crops including the larvae of Holotrichia diomphalia Bates and Euxoa oberthuri (Leech), the larvae and pupae of Leucania separata Walker, Barathra brassicae (Linnaeus) and Pieris rapac, Linne and the aphid Macrosiphum avenae (Pabricius). However, all of these 12 species, especially Anisodactylus signatus (Panzer) and Pterostichus spp., could feed on the germinating seeds of crops, although their beneficial role as predators would outweigh the damage occasionally they caused as crop pests.TV carabid beetles are susceptible to various insecticidal treatments. When a mixture of BHC and Methyl-parathion or Dimethoate, Phoxim, and Methyl-parathion were applied in the farms at the recommened rates, less beetles would be captured in the traps the next day as compared with those in the untreated plots. The most remarked reduc- tion occurred in the farms treated with a mixture of BHC and Methyl-parathion, where 70.5% less beetles were trapped even 14 days after treatment, as compared with that in the untreated plots.Data are provided to illustrate the occurrence and population densities of 12 species monitored by means of pitfall traps in spring wheat fields and soybean fields in 1981 and 1982. The seasonal activities of 7 species are described. |
