Abstract:

Neozygites floridana is an important natural enemy of Tetranychus urticae in many crops, including strawberry. In this crop there has been some changes in the production system from open field to low tunnel. This new system presents benefits to strawberry production, moreover this system increases problems with spider mites and some fungal plant pathogens; consequently increasing the use of pesticides. In order to integrate N. floridana in the management of spider mites in strawberry there are still many important aspects to be revealed on the biology, epizootiology of the fungus and the effec

Abstract:

The Allee effect corresponds to a positive relationship between population size and individual fitness. This positive relationship can cause thresholds, that is, critical population sizes below which the population becomes extinct. For species submitted to the Allee effect, the formation and cohesion of groups is therefore crucial to survival. Animals can achieve this collective behaviour through local interactions. Each individual interacts locally with conspecifics and, at the scale of the group, a unity of behaviour emerges: the animals move together, rest in the same place, or choose the s

Abstract:

Insecticidal neonicotinoid seed treatments in agriculture is a common insect pest management strategy. Seed treatments have systemic and residual toxicity, which are effective against target insect pests. However, effects on other arthropod pests is less straightforward. We evaluated the effects of a neonicotinoid seed treatment, thiamethoxam, on two soybean pests, herbivorous two-spotted spider mites (Tetranychus urticae Koch) and an omnivore and facultative predator of spider mite eggs, western flower thrips (Frankliniella occidentalis Pergande). We used greenhouse and laboratory experiments

This thesis reports laboratory and field investigations on the aspects of biology of the Stethorus vagans, an Australian ladybird that feeds on all stages of two-spotted mite, Tetranychus urticae. Aspects of the biology of S. vagans were studied in the laboratory at constant and fluctuating temperatures. They regularly fed on all stages of T. urticae and there was no significant difference in male and female longevity at different temperatures. For field studies potted French bean plants infested with T. urticae were exposed in the field. Adult S. vagans was found to consume a range of alterna

Abstract:

Laboratory experiments were conducted to evaluate Tetranychus urticae Koch dispersal response 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 urticae oviposition site selection in response to residues of fenvalerate and permethrin, at two levels of residue deposition. When pyrethroid-free leaf surface was available, nearly all eggs were found on the untreat

Abstract:

The growing demand for strawberries has imposed challenges, especially regarding the control of pests. Many farmers report problems with reduced chemical control efficiency, probably due to selection of resistant populations of insects and mites. An alternative is the use of biological control using pathogenic fungi as a tool in integrated pest management. Metarhizium spp. (Hypocreales: Clavicipitaceae) are generalist entomopathogenic fungi with worldwide distribution and can cause diseases in a large number of hosts. Many studies on the development of Metarhizium as a biological control agent

The aim of this study was to investigate the usefulness of image analysis for studying mite behaviour. Image analysis was used to convert video recordings of mites' locomotory behaviour into a series of x,y coordinates that, when joined, closely resemble the paths of mites. The coordinates were also used to calculate walking speed, direction of travel, turning frequency, turn bias and tortuosity. Two experimental arenas were developed and used to study the movement of three mite species: 1) a leaf disc arena for two-spotted spider mite, Tetranychus urticae Koch and European red mite, Panonychu

The two-spotted spider mite (TSSM), Tetranychus, urticae Koch, is one of the most serious pests in regions where hops,Humu/us lupulus L., are grown. Resistant cultivars would be ideal to reduce plant damage caused by this pest. Studies on the biological interaction between cultivated hop cultivars and TSSM were conducted over three growing seasons to gain a greater understanding of plant mechanisms involved in the response to mite attack under both natural and controlled environmental conditions. In field observations, the results revealed a generalised pattern of growth and decline i

The two-spotted spider mite (TSM), Tetranychus urticae Koch, is an important pest of many greenhouse and field crops worldwide. The development of resistance in TSM populations to chemical acaricides, allied with public health concerns about pesticide residues, has motivated the search for alternative control measures to suppress the pest. Hyphomycetous fungi are promising agents for mite control and the fungus Beauveria bassiana (Bb) (Balsamo) Vuillemin was investigated in this study as a biocontrol agent.

Aspects of the general biology and ecology of Two Spotted Spider Mite (TSSM), Tetranychus urticae Koch, and its natural enemies in hop fields were investigated in the years 1987-88 and 1988-89. The investigation found that TSSM overwinters in hollow cavities of hop twigs in the litter around hop rootstocks. In late August to early September TSSM becomes active to lay eggs and progressively colonizes hop on the lower surface of hop leaves.
