food choice in omnivorous animals is influenced by the balance of nutritional needs, food availability, and quality of a particular food items. here, we study whether omnivorous onion thrips, thrips tabaci lindeman, feed on the eggs of its competitor tetranychus urticae koch (acari: tetranychidae) when an alternative supplemental source is, or is not, available. thrips were either fed a cucumbe...

The spider mite, Tetranychus truncatus, is a polyphagous agricultural pest harboring various endosymbionts, such as Wolbachia and Spiroplasma. How they interact with each other in the same host not clear. temperature impacts their interaction endosymbionts remains largely unknown. Furthermore, little known about bacterial communities of truncatus molecular mechanism underlying regulation genes....

The predatory mite, Neoseiulus californicus (McGregor, 1954) (Acari: Phytoseiidae) is one of the principal natural enemies of tetranychid mites in several countries, promoting efficient control of those mites in several food and ornamental crops. Pest attacks such as that of the spider mite, Tetranychus urticae Koch, 1836 (Acari: Tetranychidae), is one of the problems faced by farmers, especial...

It is well known that microbial pathogens and herbivores elicit defence responses in plants. Moreover, microorganisms associated with herbivores, such as bacteria or viruses, can modulate the plant's response to herbivores. Herbivorous spider mites can harbour different species of bacterial symbionts and exert a broad range of effects on host-plant defences. Hence, we tested the extent to which...

BACKGROUND The spider mite, Tetranychus urticae, is the major strawberry pest in Brazil. The main strategies for its control comprise synthetic acaricides and predatory mites. The recent register of a commercial formula of azadirachtin (Azamax(®) 12 g L(-1) ) can be viable for control of T. urticae. In this work, the effects of azadirachtin on T. urticae and its compatibility with predatory mit...
