“…This finding may be correlated with the SO 2 emissions from the Haldia industrial complex, which may have caused a decrease in the Chrysomelidae population on this plant. This result could be compared to the study of Freitag and Hastinsgs (1973), who claimed that there was an inverse relationship between ground beetle population numbers and SO 2 emission levels in the vicinity of a pulp mill. The leaf beetle, Melasoma lapponica, avoids willows in moderately polluted SO 2 areas .…”

This paper compares the species richnesses, Bray-Curtis similarities, species diversities, evennesses, and the results of various analyses (multivariate, logarithmic series, and lognormal distribution analyses) of insects from four orders (viz., Hemiptera, Orthoptera, aculeate Hymenoptera, and Coleoptera) inhabiting a medicinal plant, Calotropis procera among eight sites within industrial and nonindustrial zones in the Purba Medinipur district (erstwhile Midnapore), West Bengal, India. Both cluster analysis and principal component analysis indicate an effect of industrialization on the diversity of the four insect orders. The species community at each site exhibits an almost pure lognormal distribution. Bootstrap estimation of species diversity also points to the effect of industrialization. A comparison of the values of x and N/S of the logarithmic series indicates a typical relationship between the species community and its diversity. The number of unique species among the eight study sites is 6 according to jackknife estimation. Beta-diversity analysis of the samples shows the impact of industrialization on the abundances and species richness of the insects. Altogether, 16 types of analytical procedure are applied for this purpose, and their suitabilities for this kind of data set are assessed. Disturbance, probably due to industrial emissions, has changed the compositions and structures of the insect communities out to a distance of at least 6 km from the core industrial area.

“…Carabids have already received some use as indicators of perturbation. Freitag et al (1973) related decreased abundance of ground beetles to the pollution effects of a paper mill. Lavigne and Campion (1978) reported increased numbers of carabids in grassland perturbed by addition of water and nitrogen.…”

The response of carabid beetles to differences in tillage and chemical use was studied using four matched pairs of sites. Abundance and species richness were significantly different between treatments, but four commonly used measures of diversity were relatively insensitive indicators of change. It is suggested that the use of diversity indices in impact assessment is redundant or, when used with ground beetles, misleading.

“…For instance, in surveys of large geographical areas where the objective is qualitative inventory and comparison of assemblages, pitfall trapping is the only realistic alternative presently available (Niemela et al 1990(Niemela et al , 1993. This kind of work may include assessing and monitoring environmental problems by using carabids as an "indicator7' group (Freitag et al 1973;Niemela et al 1990). In agricultural situations, where the subject of interest is the potential impact of predators in a crop (e.g.…”

Sampling Carabid Assemblages With Pitfall Traps: The Madness and the Method

1994

We describe a litter-washing technique for collecting quantitative samples of ground-beetles (Carabidae), and compare the results with those from liner extraction by Tullgren funnels and pitfall (rapping. We also compare performance of four types of pitfall traps across five habitats. Carabid species composition from litter washing and funnel extraction was similar but washing revealed higher densities. Large-bodied species predominated in pitfall samples and small-bodied species predominated in litter samples. Uncovered, round pitfall traps yielded generally higher catches than rectangular or covered, round traps but the pattern was not consistent over all species or the five habitats. Ecological studies of carabid populations and assemblages using pitfall traps may be improved if they are both designed and interpreted in light of the biology of the group and with regard to the deficiencies of pitfall trapping as discussed here and elsewhere.
