Control of Tomato Pinworm (Tpw) Keiferia Lycopersicella with Fermentation Product Insecticides, Spring 1995

Focal Spot, Spring 1995

Selection of processing tomato genotypes with high acyl sugar content that are resistant to the tomato pinworm.

Acyl sugars are allelochemicals present at high concentrations in leaves of accessions of the wild tomato Solanum pennellii; they confer resistance to a large number of arthropod pests, including the tomato pinworm, Tuta absoluta (Lepidoptera, Gelechiidae). Accession 'LA716', with high contents of acyl sugars in the leaves, was used as a source of resistance to start a genetic breeding program ...

Tomato psyllid behavioral responses to tomato plant lines and interactions of plant lines with insecticides.

Adult tomato psyllid, Bactericerca (Paratrioza) cockerelli (Sulc) (Homoptera: Psyllidae), behavioral responses were evaluated for five tomato plant lines and for the interactions of insecticides with four commercial cultivars. Plant lines tested included the commercial 'Shady Lady', 'Yellow Pear', '7718 VFN', 'QualiT 21', and the plant introduction line PI 134417. Insecticides included a kaolin...

Tropical Insect Chemical Ecology

In this chapter we describe the current state of tropical insect chemical ecology in Latin America with the aim of stimulating the use of this important tool for future generations of technicians and professionals workers in insect pest management. Sex pheromones of tropical insects that have been identified to date are mainly used for detection and population monitoring. Another strategy terme...

The 1995 AAAI Spring Symposia Reports

The symposium entitled Empirical Methods in Discourse Interpretation and Generation had two goals: (1) to investigate the empirical methods that can be used in the development and evaluation of computational theories of discourse and (2) to develop a set of shared resources for the computational discourse community. The workshop was successful at achieving the first goal because of the large nu...
