Strawberry fruit, western flower thrips and two-spotted spider mites were exposed to a range of ethyl formate (EF) concentrations from 0.8 to 2.4%. Ethyl formate treatments included both single and multiple applications of EF, the multiple applications having a venting period between each application. Additionally, target pests were exposed to EF and elevated levels of CO2 from 5 to 95 kPa, bal...

two-spotted spider mite, tetranychus urticae koch (acari: tetranychidae), is one of the most injurious pests of fruits, vegetables and ornamental plants worldwide, both outdoor and indoors. currently the main method of control of this pest is through application of pesticides which is mostly accompanied by the resistance of the pest against pesticide(s). the resurgence of resistant mite populat...

The two-spotted spider mite, Tetranychus urticae, is a chelicerate herbivore with an extremely wide host range and an extraordinary ability to develop pesticide resistance. Due to its responsiveness to natural and synthetic xenobiotics, the spider mite is becoming a prime pest herbivore model for studies of the evolution of host range, plant-herbivore interactions and mechanisms of xenobiotic r...

A vermicompost, produced commercially from food wastes, was tested for its capacity to suppress populations and damage to plants, by two-spotted spider mites (Tetranychus urticae), mealy bugs (Pseudococcus sp.) and aphids (Myzus persicae), in the greenhouse. A range of mixtures of food waste vermicompost and a soil-less bedding plant growth medium Metro-Mix 360 (MM360) was tested in cages (40 c...

the two spotted spider mite tetranychus urticae koch is one of the polyphagous pests of crops worldwide. due to undesirable effects of synthetic pesticides such as expression of resistance in mites, this research was conducted to achieve alternative safe compounds to environment. therefore, ovicidal activity of essential oils of eucalyptus salmonophloia f. muell and eucalyptus kingsmillii maide...

Common bean (Phaseolus vulgaris L.) is one of the most important and widely cultivated Legume in the world. The two-spotted spider mite (TTSM), is one of the most important agricultural pests. This research provided some evidence of the applicability of CuO nano particles and nano capsule for controlling TTSM. To evaluate the effect of copper nano-capsules on the populations of TSSM from red be...

repeatability, (the consistency with which a given trait is expressed) of aggressiveness against prey (attack latency) in gravid females of the predatory mite neoseiulus californicus (mcgregor) was examined. in two experiments, prey - conspecific individuals, the onion thrips thrips tabaci (lindeman), and the two-spotted spider mite tetranychus urticae koch- were repeatedly offered in various n...

The negative cross-talk between induced plant defences against pathogens and arthropod herbivores is exploited by vectors of plant pathogens: a plant challenged by pathogens reduces investment in defences that would otherwise be elicited by herbivores. This negative cross-talk may also be exploited by non-vector herbivores which elicit similar antiherbivore defences in the plant. We studied how...
