Abstract
The oviposition and feeding behaviour of the wheat bug (Nysius huttoni White) was studied in the laboratory. Eggs were mainly laid in the soil with a few laid on the host plants and container wall. Mated females laid more eggs than virgin ones within a 24 h period. Host plant species had no effect on the total number of eggs laid in a 24 h period but had significant influence on egg allocations on different sites by females. Pre-feeding and total feeding periods, and feeding frequency on swede (Brassica napus rapifera Metzger) seedlings within a 1 h period were not significantly different between sexes and between instars. However, the time spent on the first feeding was significantly longer than that on any other feedings. N. huttoni preferred stems to petioles and leaves for feeding.
