In order to study the efficacy of Sunn pests' parasitoid flies, four overwintering sites of Sunn pest in Isfahan, including mountains of Kolahghazy, Panjeh, Jozdan and Sacepid were selected and from each site four different elevations were designated as sampling sites. During 1997, at least 6 and, in 1998, three samples were taken at each sampling site. In spring 1998, four wheat and barley fie...

Liriomyza huidobrensis (Blanchard) is an economically important and highly polyphagous worldwide pest. To establish a temperature-dependent phenology model, essential for understanding the development and growth of the pest population under a variety of climates and as part of a pest risk analysis, L. huidobrensis life-table data were collected under laboratory conditions at seven constant temp...

Integrated pest management (IPM) is a method of reducing economic, human health, and environmental risks from pests and pest management strategies. There are questions about the long-term success of IPM programs in relation to continued use of pesticides in agriculture. Total pounds of pesticides applied is a mis-measure of the impact of IPM in agriculture. A more complete measurement of the lo...

Pesticides including insecticides and miticides are primarily used to regulate arthropod (insect and mite) pest populations in agricultural and horticultural crop production systems. However, continual reliance on pesticides may eventually result in a number of potential ecological problems including resistance, secondary pest outbreaks, and/or target pest resurgence [1,2]. Therefore, implement...

The sweetpotato whitefly Bemisia tabaci Q species is a recent invader and important pest of agricultural crops in China. This research tested the hypothesis that the Q populations that establish in agricultural fields in northern China each year are derived from multiple secondary introductions and/or local populations that overwinter in greenhouses (the pest cannot survive winters in the field...

Integrated Pest Management (IPM) can be defined as “an ecologically based pest control strategy that relies heavily on natural mortality factors and seeks out control tactics that disrupt these factors as little as possible” (Flint & Bosch, 1981). IPM began to be applied because the extensive use of chemical insecticides show different types of environmental damages, as development of resistant...

The vinegar fly Drosophila suzukii (Matsumura) (Diptera Drosophilidae), spotted wing drosophila, is a highly polyphagous invasive pest endemic to South East Asia, which has recently invaded western countries. Its serrated ovipositor allows this fly to lay eggs on and damage unwounded ripening fruits, thus heavily threatening fruit production. D. suzukii is spreading rapidly and economic losses ...

W hich urban pest is the most difficult to control? Most PMPs say ants. But the answer to this question has shifted completely over the past 20 years — from cockroaches to ants. Today, few people consider the German cockroach a difficult pest to manage. What made the change is the invention of highly effective baits, in particular, gel baits. Then, the question is, why is the German cockroach s...

(Photo: Boris Hrasovec, Faculty of Forestry, Bugwood.org) The IAEA’s support to Member States in the field of insect pest control has mainly focused on the Sterile Insect Technique (SIT), which is a type of insect birth control, where mass reared and systematically released sterile males of the target pest insect mate with wi...
