Abstract:The effects of mechanical barriers (1.5 m high, 3 m long) on the distribution of aerial thrips above a lettuce (Lactuca sativa) field in Kula, Hawaii, were measured. Barriers were made from an aluminum polyvinyl net. Significantly fewer thrips were caught on sticky traps closest to barriers. The mean overall reduction in thrips due to barriers was 45.6 ± 7 thrips per set of five traps per week, which constitutes about a 10% reduction. There was also a significant effect due to barrier and trap position. Thrips were significantly more numerous on the side of the field corresponding to the prevailing wind direction.
