Bu çalışma 2017-2018 yıllarında Adana ili soğan ekim alanlarında zararlı türler ile bunların parazitoit ve predatörlerinin saptaması amacıyla yapılmıştır. Çalışma sonucunda 4 takıma bağlı 9 familyadan 18 tür belirlenmiş olup; bu içerisinde soğanda en çok zarar yapan türlerin; Eobania vermiculata Müller, Thrips tabaci Lindeman Frankliniella occidentalis Pergande olduğu belirlenmiştir. Saptanan y...

effects of four pesticides (imidacloprid, dichlorvos, pymetrozine and abamectin) were evaluated on life table parameters of orius albidipennis (reuter). pesticides were used at the concentrations recommended by the manufacturers. the bioassays were carried out using drum-cell method, in a growth chamber at 27 â± 1âºc, r.h. of 65 â± 5% and 16 h photo phase. the net reproductive rate (r0) value f...

Injury caused by picture-winged flies or corn silk flies (Diptera: Ulidiidae) is a major limiting factor of corn (Zea mays L.: Poales: Poaceae) yields in Florida. Growers have relied heavily on chemical insecticides for control of these pests. However, we are exploring other methods, such as the use of biological control by predatory arthropods, which may be factors in an integrated pest manage...

This paper uses a methodology based in fuzzy sets theory in order to describe the interaction between the prey, Aphis glycines (Hemiptera: Aphididae) the soybean aphid, and its predator, Orius insidiosus (Hemiptera: Anthocoridae). Economic thresholds were already developed for this pest. The aim of this investigation was to develop a simple and specific methodology by fuzzy rule-based system to...

Abstract Augmentative biological control in protected crops relies mainly on omnivorous predators. Their performance as agents (BCA) depends several characteristics of the species, which turn may differ among strains within a species. We have recently reported achievement two Orius laevigatus (Hemiptera: Anthocoridae) showing significant larger body size or better fitness when feeding pollen, h...

The western flower thrips, Frankliniella occidentalis (Pergande) attacks a large number of crop plants. The current insecticides have caused resistance in insects and have caused outbreaks of thrips. In many instances, alternative methods of insect management and natural products, offer adequate pest control and pose fewer hazards. Several species of minute pirate bugs of the genus Orius play a...
