| the impact of eriophyoids on crops: recent issues on aculus schlechtendali, calepitrimerus vitis and aculops lycopersici. | the nature of the damage caused by eriophyoid mites and the assessment of yield losses still require detailed studies if appropriate control and risk mitigation strategies are to be planned. the economic importance of eriophyoid mites is increasing worldwide and a lot of species have reached a permanent pest status in certain crops, while others represent a quarantine threat for several countries. due to their relevant role in europe and elsewhere, three eriophyoid mites that have been frequentl ... | 2010 | 19757100 |
| influence of life diet on the biology and demographic parameters of agistemus olivi romeih, a specific predator of eriophyid pest mites (acari: stigmaeidae and eriophyidae). | the influence of various life diets on the biology and demographic parameters of the predatory mite, agistemus olivi romeih, was studied under laboratory conditions. a. olivi successfully developed and reproduced on all of the tested eriophyid mites. feeding on aceria mangiferae sayed enhanced the development of a. olivi, resulted in the shortest mean generation time and was the most commensurate food for the ovipostion of the predator, as exhibited by the highest fecundity and net reproductive ... | 2012 | 24575223 |
| defense suppression benefits herbivores that have a monopoly on their feeding site but can backfire within natural communities. | plants have inducible defenses to combat attacking organisms. hence, some herbivores have adapted to suppress these defenses. suppression of plant defenses has been shown to benefit herbivores by boosting their growth and reproductive performance. | 2014 | 25403155 |
| predation, development, and oviposition by the predatory mite amblyseius swirkii (acari: phytoseiidae) on tomato russet mite (acari: eriophyidae). | predation, development, and oviposition experiments were conducted to evaluate amblyseius swirskii (athias-henriot) (acari: phytoseiidae) as a potential biological control agent for tomato russet mite, aculops lycopersici (massee) (acari: eriophyidae), which can be a serious pest of greenhouse tomatoes. results showed that a. swirskii attacked all developmental stages of a. lycopersici and had a type ii functional response at the prey densities tested. the attack rate and handling time estimates ... | 2010 | 20568599 |
| factors affecting mite herbivory on eggplants in brazil. | the objective of this study was to determine effects of total rainfall, mean temperature, predators, height of canopy, levels of nitrogen and potassium in leaves, and the density of leaf trichomes on the attack intensity of tetranychus evansi and t. urticae (acari: tetranychidae) and aculops lycopersici (acari: eriophyidae) in five plantations of the eggplant solanum melongena var. 'natu nobilis' in two regions of brazil. higher numbers of individuals of a. lycopersici, t. evansi and t. urticae/ ... | 2003 | 14974689 |
| herbivory-associated degradation of tomato trichomes and its impact on biological control of aculops lycopersici. | tomato plants have their leaves, petioles and stems covered with glandular trichomes that protect the plant against two-spotted spider mites and many other herbivorous arthropods, but also hinder searching by phytoseiid mites and other natural enemies of these herbivores. this trichome cover creates competitor-free and enemy-free space for the tomato russet mite (trm) aculops lycopersici (acari: eriophyidae), being so minute that it can seek refuge and feed inbetween the glandular trichomes on t ... | 2013 | 23238958 |
| definition of the concordis species group of the genus euseius (acari: phytoseiidae), with a morphological reassessment of the species included. | phytoseiidae (acari) is the best known family of predatory mites. within this family, euseius wainstein is one of the largest genera. the species of this genus have generalist feeding behavior, including in their diet mites and pollen. some studies have demonstrated the potential of certain euseius species to control pest mites. euseius concordis (chant) has been mentioned in the literature as potentially useful for the control of the tomato russet mite, aculops lycopersici (tryon) (eriophyidae) ... | 2015 | 26624744 |
| drought stress promotes the colonization success of a herbivorous mite that manipulates plant defenses. | climate change is expected to bring longer periods of drought and this may affect the plant's ability to resist pests. we assessed if water deficit affects the tomato russet mite (trm; aculops lycopersici), a key tomato-pest. trm thrives on tomato by suppressing the plant's jamonate defenses while these defenses typically are modulated by drought stress. we observed that the trm population grows faster and causes more damage on drought-stressed plants. to explain this observation we measured sev ... | 2017 | 29188401 |
