the leopard moth, zeuzera pyrina (l.) (lepidoptera: cossidae) is a serious pest of walnut and apple trees in iran. one of the control methods for this pest is the mass trapping of males using pheromone traps. to determine the best size and color of traps, four different colors (green, yellow, white, gray) and two different sizes (delta shape with standard adhesive surface, 19 × 22 cm and trapez...

applying a precise forecasting method is necessary to achieve acceptable results in ipm programs. performances of the wing and delta pheromone traps for forecasting the codling moth phenology were compared with physiological time data based on degree-hours. six pheromone traps (three wing and three delta style) were applied for the monitoring of the codling moth population. traps were placed in...

Field experiments were conducted to determine the effectiveness of the floral compound phenylacetaldehyde in increasing capture of fall armyworm, Spodoptera frugiperda , males in pheromone-baited traps. Plastic Unitraps were placed in cotton and corn fields in north-central Florida and were baited with commercial sex pheromone and synthetic phenylacetaldehyde released from hollow polyethylene s...

Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), commonly known as the Asian longhorned beetle, is a wood-boring invasive species introduced from Asia to North America and Europe in solid wood packing material. Efficient monitoring traps are needed to assess population density and dispersal in the field and to detect new introductions at ports of entry. For this purpose, we co...

BACKGROUND Field trapping experiments were conducted to evaluate the attractiveness of five different pheromone blends as well as the impact of trap design on attractiveness towards cocoa mirids, Sahlbergella singularis Hagl. and Distantiella theobroma (Dist.), in Cameroon. RESULTS A total of 361 adults of S. singularis (359 males and two females) were caught. The highest numbers of mirids we...

Objectives: 1. Assess the attractancy of non-pheromone baits for leafrollers, lacanobia fruitworm and codling moth compared to pheromone traps and determine the reproductive status of female moths attracted to the non-pheromone baited traps. 2. Determine the area of attractancy for non-pheromone baits using release-recovery methods. 3. Develop action thresholds for leafrollers, lacanobia fruitw...

Larvae of Prionus californicus Motschulsky (Coleoptera: Cerambycidae) feed on the roots of many types of woody perennial crops and are serious pests of hop in the northwestern United States. The adult males are strongly attracted to a volatile sex pheromone, (3R,5S)-3,5-dimethyldodecanoic acid, that is produced by females. Here, we summarize the results of field experiments that evaluated the p...
