Control of Aedes taeniorhynchus and Culex quinquefasciatus emergence with sustained release Altosid sand granules and pellets in saltwater and freshwater test plots.
The efficacy of sustained release Altosid sand granules to control adult Aedes taeniorhynchus and Culex quinquefasciatus emergence was investigated. Sand granules applied at a 7-day preflood application rate of 5.6 kg/ha controlled 99% of the Ae. taeniorhynchus emergence in saltwater plots for 44 days posttreatment and 35% of Cx. quinquefasciatus in freshwater plots. A 5.6 kg/ha rate controlled 100% of the Ae. taeniorhynchus emergence for 30 days posttreatment in semi-permanent saltwater plots. Altosid pellets were used at the label rate for comparison. Sand granules applied at 11.2, 16.8 and 22.4 kg/ha against Cx. quinquefasciatus in freshwater plots gave 98% emergence inhibition at the 22.4 kg/ha rate 37 days posttreatment, 93% at 16.8 kg/ha for 22 days, and 100% at 11.2 kg/ha rate for 16 days.
