AbstractThe beet leafhopper, Circulifer tenellus (Baker), was found to be significantly attracted to the color yellow. Yellow, opaque plastic cards coated with a sticky substance were shown to be an effective survey tool for monitoring adult beet leafhopper. Traps with different hues of yellow (wavelengths of 510 and 588 nm) showed no significant differences between trap catches. The commonest flight strata at a host site was at ground level, where significantly higher numbers of adults were trapped than at heights of 0.3, 0.6, 0.9, 1.5, 2.1, and 2.7 m above the ground. The ground level is the optimum location for a yellow sticky trap when monitoring C. tenellus.

AbstractPheromone trapping studies from 1979 to 1981 showed that there were two periods of San Jose scale, Quadraspidiotus perniciosus (Comstock), male flight activity annually in western New York apple orchards. Spring flight, which resulted from overwintering black caps, began at ca. 94–140 degree-days (base 10 °C from 1 March) and occurred during bloom in the apple varieties studied. First generation crawlers emerged at ca. 360 degree-days. Second generation crawlers emerged at ca. 890 degree-days and were active throughout September. Regression analyses showed a logistic relationship between crawler density and fruit infestation, and inverse linear relationships between pheromone trap catches and San Jose scale infestation levels within trees.

EFFECT OF COLOR ON STICKY-TRAP CATCHES OF PHOLETESOR ORNIGIS (HYMENOPTERA: BRACONIDAE), A PARASITE OF THE SPOTTED TENTIFORM LEAFMINER PHYLLONORYCTER BLANCARDELLA (LEPIDOPTERA: GRACILLARIIDAE)

Pholetesor Ornigis

AbstractThe effect of trap color on sticky-trap catches of Pholetesor ornigis Weed was studied in experimental and commercial apple orchards during each of the parasite's 3 yearly activity periods during 1982–1984. Seven enamel and 5 fluorescent paints were compared in 8 trials. There was considerable between-trial variation in the percentage of the total number of P. ornigis caught on a trap of one color. Trap color had a significant effect on the total number of parasites caught. There were no consistent differences in the relative attractiveness of the different colors to males and females. During 1984, males comprised more than 75% of all parasites trapped during each of the 3 activity periods. The sex ratio of the adult population emerging in study orchards during 2 of these activity periods was approximately 1:1.

Aulacaspis Tegalensis

By means of sticky traps and a suction trap, it was demonstrated on a plot of sugar-cane at Kawanda Research Station, Uganda, that large numbers of crawlers of Aulacaspis tegalensis (Zhnt.) become airborne (up to 10/m3). The numbers increase with wind speed up to about 2·0 m/s and then remain constant, but are depressed by increasing humidity. In laboratory experiments, crawler survival was reduced by high temperatures (30°C) and low humidities (30% r.h.), but some individuals should survive the extreme conditions sometimes experienced if airborne from morning until evening. On hatching, crawlers move upwards and towards the light, but downwards in the dark; movement is inhibited by high humidity. These behaviour responses indicate hat the presence of crawlers in the air is not accidental but a dispersal mechanism. At Arusha Chini, an isolated sugar estate in Tanzania, sticky-trap catches downwind of a windbreak confirmed that airborne dispersal of crawlers is a major source of infestation. It is shown that air currents could have carried crawlers to Arusha Chini from a source on the Kenya coast, 260 km to the east.
