Pheromone mating disruption offers selective management options for key pests
The direct management of insect pests using pheromones for mating disruption, or “attract and kill” approaches, can provide excellent suppression of key lepidopteran pests in agriculture. Important…

An historical perspective is provided of pest management programs in western apple orchards using the Washington situation as an example. The adoption of mating disruption as a key pest management…
Improvement of Navel Orangeworm (Lepidoptera: Pyralidae) Egg Traps
- R. Steenwyk, W. Barnett

- 1 February 1985
Improvement of egg traps for the navel orangeworm, Amyelois transitella, was investigated by modifying trap color, trap texture, and bait and it was found that as the amount of bait in the trap increased, so did egg deposition.

Prospects for olive fruit fly control in Calif-ornia are good, and effective manage-ment is likely to result from careful monitoring and properly timed chemical control.
Spider Mite Interactions with Photosynthesis, Transpiration and Productivity of Strawberry

Low level stress in spider mite populations caused reductions in physiological parameters at much lower population levels than was necessary to cause similar injury later in the season, and reduced physiological activity of mite-stressed plants persisted until plant recovery was observed.
Marking Pink Bollworm (Lepidoptera: Gelechiidae) with Cesium
- J. I. Moss, R. Steenwyk
- Biology
- 1 December 1982
Pink bollworm, (PBW) Pectinophora gossypiella (Saunders), adults reared on artificial diet containing 1 × 10−2 M and 1 × 10−3 M CsCl were marked with Cs which could be detected by using atomic…
Forecasting Pink Bollworm Emergence by Thermal Summation
- V. Sevacherian, N. Toscano, R. Steenwyk, R. Sharma, R. R. Sanders
- Biology
- 1 August 1977
Overwintering emergence of pink bollworm moths was monitored for 4 years in the Imperial Valley, Calif. and accumulation of degree-days was seen to be an accurate means of forecasting cumulative moth emergence under both cage and field conditions.
CONTROL OF WALNUT HUSK FLY USING REDUCED-RISK PRODUCTS
- R. Steenwyk, A. Verhaeghe, C. Debuse
- Biology
- 2004
Past research has demonstrated that effective control of WHF can be achieved with repeated applications of GF-120, however, there are some indications that GF120 should be applied earlier in the season than OP insecticides and that control of high populations ofWHF withGF-120 may be challenging.
