Color sticky board traps are used in pest management for capture of adult insect, to estimate and predict population densities in later stages. Yellow sticky board traps showed high attraction for pistachio psylla. It is important to study these relationships for the right placement of traps. For each of three repetition in one year, four pistachio trees were selected randomly in one orchard. E...

A new design of interception trap is presented based on a combination of features ofwindow and Malaise traps. The trap has been developed for study of the canopy faunas of rainforest trees, specifically Argyrodendron actinophyllum. Five such traps have been operated in SE Queensland for a year with catches being removed weekly. Coleoptera, Nematocera, Homoptera and Hymenoptera were the most abu...
Paired trap lines of Þve boll weevil pheromone traps each were placed on opposite sides of a brush line at six different sites on a plantation in the Lower Rio Grande Valley of Texas. Temperature, wind speed, and wind direction were monitored with a nearby weather station. We observed a strong negative relationship between mean daily wind speed and total daily capture of boll weevils. About hal...
