Biological Features and Population Growth of Two Southeastern European Jacquelin du Val (Coleoptera: Tenebrionidae) Strains.

A study of the biological features and the potential population growth between two laboratory strains of the confused flour beetle, Jacquelin du Val (Coleoptera: Tenebrionidae) from Greece and Serbia is conducted on cracked barley and cracked white rice. The results show that, at a species level, is able to complete development on cracked barley but not on cracked white rice. Therefore, cracked white rice proves to be an unsuitable commodity for .

Behavioural responses of (Herbst) to different types of uninfested and infested feed.

Tribolium castaneum is one of the most economically important insects that damages stored products. The effects of several infested or uninfested raw feed materials (wheat bran, coarse wheat meal, corn feed flour), feed products (compound feed for pigs and for laying hens) and flour mixed with brewer's yeast on the food-searching behaviour of T. castaneum adults were studied in a total of 48 combinations.

Ecologically acceptable usage of derivatives of essential oil of sweet basil, Ocimum basilicum, as antifeedants against larvae of the gypsy moth, Lymantria dispar.

Abstract Ethanol solutions of five fractions obtained from essential oil of sweet basil Ocimum basilicum L. (Lamiales: Lamiaceae) (F1-F5) were tested for their antifeedant properties against 2(nd) instar gypsy moth larvae, Lymantria dispar L. (Lepidoptera: Lymantriidae), in laboratory non-choice and feeding-choice experiments.

CONTROL OF DIABROTICA VIRGIFERA VIRGIFERA LE CONTE IN MAIZE SEED TREATMENT.

During the last decade of XX century, Diabrotica virgifera virgifera Le Conte became an important introduced harmful species in maize production in the northern Serbia region. The aim of this work was to assess the efficacy of imidacloprid based insecticides formulated for seed treatment in the control of D. v.

Insecticidal potential of natural zeolite and diatomaceous earth formulations against rice weevil (Coleoptera: Curculionidae) and red flour beetle (Coleoptera: Tenebrionidae).

Insecticidal potential of natural zeolites and diatomaceous earths originating from Serbia against Sitophilus oryzae (L.) and Tribolium castaneum (Herbst) was evaluated. Two natural zeolite formulations (NZ and NZ Modified) were applied to wheat at rates of 0.
