Abstract:
Objective To observe the palatability and the efficacy of the self-made cockroach gel bait in the field trial . Methods In accordance with the experimental method specified in GB /T 13917.7-2009, the amount of 24-hour-intake of self-made gel bait and fipronil granule were recorded , the number of dead cockroaches was counted , and then, the rate of water loss in 24 hours and the rate of food consumption were calculated .Field trial was performed onboard 2 naval vessels heavily infested with cockroaches . Changes in insect density index at different time points following application of gel bait were observed closely .Results The lethal rate of the 2 baits within 48 hours was all as high as 100%, which was classified as grade A .However , the ratio of bait and feed for the 2 field trails was 1.34 and 0.40.Great significance could be seen , when comparisons were made between them .Two weeks after the ap-plication of the gel bait , the insect density was decreased by 80%, and 4 to 8 week after medication the insect density could be con-trolled within a relatively low level .Conclusion As compared with the granule type bait , the self-made gel bait seemed to have better palatability.It could be applied in those heavily infested places and prolonged effective control of insects could be achieved ideally .
