The true bug Oxycarenus lavaterae has spread northwards through Europe from the Mediterranean at the beginning of the 21st century. Temperature and photoperiod in particular countries are important for the prediction of further spread. The timing and

One of the factors affecting the effectiveness of predatory coccinellids in an aphid infested crop is the food specificity of the predator. The response towards six species of aphids (Sternorrhyncha: Aphididae) was therefore tested in one of the most

The cold hardiness of individuals from overwintering populations of a freeze susceptible bug Pyrrhocoris apterus from central and southern Europe differed significantly. Supercooling point (SCP) correlated well with both lethal temperature (LT50) and

Length of development of larvae and pupae of the invasive alien ladybird beetle Harmonia axyridis, their survival rates, sex ratio, and fresh mass of the emerged adults were measured at three contrasting levels of relative air humidity: 30, 60, and 9

Some species of ladybird beetles (Coleoptera: Coccinellidae) mate both before and after overwintering. The purpose of the pre-diapause mating was studied in the alien invasive ladybird Harmonia axyridis (Pallas 1773). Our study demonstrates the persi

Investigations on ground beetles in potato fields were conducted in Bulgaria in 2000, 2001 and 2004. Pitfall traps were used to compare the biodiversity of carabid beetles in Bacillus thuringiensis (Bt) and conventional (non-Bt) potato cultivars. A t

Colorado potato beetle, Leptinotarsa decemlineata Say, is the most destructive insect pest of potatoes. When the population of beetles is high, plants can be completely defoliated and commercial potato production is nearly impossible without control
