Synergism Between Entomopathogenic Nematodes And Bacillus Thuringiensis Crops: Integrating Biological Control And Resistance Management, Aaron J. Gassmann, S. Patricia Stock, Mark S. Sisterson, Yves Carriere, Bruce E. Tabashnik
Synergism Between Entomopathogenic Nematodes And Bacillus Thuringiensis Crops: Integrating Biological Control And Resistance Management, Aaron J. Gassmann, S. Patricia Stock, Mark S. Sisterson, Yves Carriere, Bruce E. Tabashnik

The past decade has witnessed a continual increase in the use of crops genetically modified to produce insecticidal toxins from the bacterium Bacillus thuringiensis (Bt). This presents the challenge of designing agricultural systems to manage pests and the evolution of resistance to Bt. We tested whether entomopathogenic nematodes might act synergistically with Bt crops by killing pests in non-Bt refuges and by increasing the fitness costs of resistance to Bt. We also tested whether insect mortality and fitness costs were affected by the cotton phytochemical gossypol. The entomopathogenic nematode Steinernema riobrave increased the fitness cost of Bt resistance, indicating that …

In Utah, there are typically three generations of corn earworm (CEW) each year. The first generation of adults either come from overwintering pupae (southern and central Utah), or migrate into northern Utah. The adult moth is tannish brown with a 1 1/2 inch wingspan. The front wings are marked with a distinct dark spot in the center and darker bands near the outer margins. The hind wings are lighter tan, with a dark band along the outer margins. The male moths have green eyes. Moth flight occurs primarily on warm, overcast evenings. Moth populations can be monitored using pheromone or …

Nos ecossistemas de produção de arroz irrigado, os insetos-praga são considerados uma das limitações na produção mundial. Diante desse fato, diversas formas de controle vêm sendo pesquisadas para minimizar o problema. O uso contínuo de produtos fitossanitários ocasiona a resistência das pragas, além do aumento da população de pragas secundárais. Como alternativa, o uso do controle biológico, através de inimigos naturais, como predadores, parasitóides e patógenos, se revela capaz de regular as pragas em seu ambiente natural, reduzindo a densidade das populações e conseqüentemente os danos às plantas hospedeiras. Sendo assim, nesse trabalho de revisão são apresentados dados sobre a …

The Role Of Spiders In The Detrital Food Web Of An Eastern Deciduous Forest, Erin Elizabeth Hladilek
The Role Of Spiders In The Detrital Food Web Of An Eastern Deciduous Forest, Erin Elizabeth Hladilek
University of Kentucky Doctoral Dissertations
Historically, terrestrial food web research has focused on describing the structure of aboveground grazing webs, and determining how interactions among plants, herbivores and higher trophic levels influence primary productivity. Detrital food webs however, play a significant role in regulation of ecosystem dynamics through direct impacts on decomposition. Unraveling the complex nature of detrital food web structure is critical to developing a better understanding of ecosystem function. Therefore the primary objective of this research was to describe the structure of the leaf-litter food web in a temperate deciduous forest, with emphasis on interactions between a community of generalist predators, the forest-floor …
Colorado Potato Beetle Resistance To Insecticides, Andrei Alyokhin, Mitchell Baker, David Mota-Sanchez, Galen Dively, Edward Grafius
Colorado Potato Beetle Resistance To Insecticides, Andrei Alyokhin, Mitchell Baker, David Mota-Sanchez, Galen Dively, Edward Grafius

The Colorado potato beetle, Leptinotarsa decemlineata (Say), is widely regarded as the most important insect defoliator of potatoes. Its current range covers about 16 million km2 in North America, Europe, and Asia and continues to expand. This insect has a complicated and diverse life history, which is well-suited to agricultural environments, and makes it a complex and challenging pest to control. Dispersal, closely connected with diapause, feeding, and reproduction, allow the Colorado potato beetle to employ "bet-hedging" reproductive strategies, distributing its offspring in both space (within and between fields) and time (within and between years). The Colorado potato beetle played …
