ABSTRACT

In evaluating various time periods for ULV adulticiding potential, the Central Massachusetts Mosquito Control Project (CMMCP) and the Norfolk County Mosquito Control Project conducted mosquito surveillance using programmable collection devices to observe the host-seeking activity periods for local mosquito species.  Collections were made in multiple environments for 3 hour intervals around sunset, being the point of interest.  Two collection periods were prior to sunset, with another four following sunset.  The collections were identified into several target groups including Aedes vexans, Coquillettidia perturbans, Culex pipiens/restuans, Culiseta melanura, Ochlerotatus canadensis, Psorophora ferox, and an Anopheles group which included Anopheles punctipennis and Anopheles quadrimaculatus.  Most species showed relatively little activity until the period before sunset.  Sunset was then followed by the largest activity period for most targeted mosquito groups, except Psorophora ferox, which was most active just prior to sunset.  These preliminary findings reinforce the present adulticiding protocol for CMMCP, which is to commence ULV applications at sunset.  Collections may be continued in upcoming seasons to determine if these results can be further established.  Effort may be made to place rotator traps in elevated stands in hopes of collecting greater numbers of Culex pipiens/restuans.  Presentation will include background on host-seeking activity, project methods, results, and application of findings.
