ANALYSIS OF VARIATIONS IN SUSCEPTIBILITY AND TRANSCRIPTOME RESPONSES IN TOMATO TO TWO-SPOTTED SPIDER MITE FEEDING
The two-spotted spider mite (Tetranychus urticae Koch) is a pest of tomatoes (Solarium lycopersicum) worldwide. The aim of this study was to generate data for comparison of spider mite resistant and susceptible tomato cultivar transcriptiome responses to mite feeding. Cultivars were screened for …

Effect of Nitrogen Fertilizer Rates and Two-Spotted Spider Mite Incidence on 'Strawberry Festival' Strawberry Cultivar Performance
… information on nutrient and pest management is limited.</p> <p>The overall objective of this study was to determine the response of ‘St. Festival’ strawberry cultivar to different nitrogen fertilizer rates in order to develop a fertilization program for strawberries grown under high tunnel …

Sex-specific aging in two-spotted spider mite Tetranychus urticae: Effects of diet, social environment and predator-induced stress
… the fitness of both sexes. Meanwhile, I tested two evolutionary hypotheses, antagonistic pleiotropy hypothesis of George Williams and disposable soma theory of Kirkwood and Holliday, which postulated that the survival and reproduction trade off with each other. To address these questions, I …

The Effect of Plant Nutrition on the Reproductive Rate and Susceptibility to Malathion of Two Strains of the Two-Spotted Spider Mite, Tetranychus telarius (L.)
… rate and susceptibility to malathion of two strains of the two-spotted spider mite. The two strains of mites used as test organisms are characterized by their widely different levels of susceptibility to phosphate acaricides. Lima bean plants were grown in quartz sand and supplied …

Oviposition and dispersal responses of the two spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) to fenvalerate and permethrin residues in soybeans Glycine max (L) Merrill
… to fenvalerate and permethrin. A petri dish spider mite trap which allows the partitioning of the dispersal response into spindown and walkoff categories was developed. Fenvalerate induced the more severe dispersal response. A greenhouse experiment was conducted to evaluate Tetranychus …

Influence of light conditions on the dynamics of Tetranychus urticae and its control by the predatory mite Neoseiulus californicus
… of LED light exposure on the dynamics of the two-spotted spider mite (Tetranychus urticae) and its control by the predatory mite Neoseiulus californicus. Three light treatments were applied: natural light, 12h LED light and 12h dark, and continuous 24h LED light. Spider mite and predator …

Thermal biology and establishment potential of two non-native candidate biological control agents, Nesidiocoris tenuis Reuter (Hemiptera: Miridae) and Lysiphlebus testaceipes (Cresson) (Hymenoptera: Braconidae, Aphidiinae), in the U.K.
… the establishment potential of these two species in cool temperate climates typical of northern Europe. Laboratory results demonstrated a low level of cold tolerance in \(N.\) \(tenuis\) with a developmental threshold of 12.9°C and no indication of ability to diapause. Field trials …
