Insect-plant interactions involving the cultivated tomato and its relatives in the genus Lycopersicon have been intensively studied for several decades, resulting in one of the best documented and…
Integration of Insect-Resistant Genetically Modified Crops within IPM Programs

This chapter reviews the defining elements of IPM and examines the attributes of insect-resistant GM crops as IPM tools.

A nonalkaloid insecticide was isolated from the wild tomato Lycopersicon hirsutum f. glabratum and identified as 2-tridecanone, a compound 72 times more abundant in the wild tomato than in the…
The Role of Weed Hosts and Tobacco Thrips, Frankliniella fusca, in the Epidemiology of Tomato spotted wilt virus.
The findings document the relative potential of a number of common annual, biennial, and perennial plant species to act as important reproductive sites for F. fusca and as acquisition sources of TSWV for spread to susceptible crops.
Role of Visual Contrast in the Alighting Behavior of Harmonia axyridis (Coleoptera: Coccinellidae) at Overwintering Sites
It is suggested that visual intensity contrast is key to understanding the behavior of H. axyridis in autumn and some commonly accepted ideas regarding choice of overwintering sites are called into question.
Quantifying Food Consumption and Growth in Insects
In short-term (within one instar) experiments quantifying insect behavior, the maximum amount of food an insect can eat is not likely to vary directly with body weight, so it is more appropriate to relate consumption to the weight of the insect at the beginning of the test, not to mean weight.
Overwintering of Frankliniella fusca (Thysanoptera: Thripidae) on Winter Annual Weeds Infected with Tomato spotted wilt virus and Patterns of Virus Movement Between Susceptible Weed Hosts.
Overwintering of tobacco thrips, Frankliniella fusca, was investigated on common winter annual host plants infected with Tomato spotted wilt virus (TSWV), suggesting that overwintering inoculum levels in an area can increase rapidly during the spring in susceptible weed hosts prior to planting of susceptible crops.
Life systems of polyphagous arthropod pests in temporally unstable cropping systems.
The life systems of three selected polyphagous pests are presented to demonstrate how an understanding of such systems in agricultural ecosystems improves the ability to predict and hence manage these populations.
Effects of tomato spotted wilt virus isolates, host plants, and temperature on survival, size, and development time of Frankliniella occidentalis
Results demonstrate significantly improved survival and a small but significant decrease in development time of F. occidentalis on TSWV‐infected plants, which resulted from the combined influence of the direct effects of the virus on infected thrips and plant‐mediated effects resulting from virus infection of the thrips' host plant.

Mating disruption proved to be an alternative to organophosphate insecticides for managing oriental fruit moth populations in North Carolina apple orchards and provided excellent trap shutdown and was significantly more effective than sprayable pheromone formulations.
