J. Isoe et al., OVIPOSITION RESPONSES OF CULEX TARSALIS AND CULEX-QUINQUEFASCIATUS TOAGED BERMUDA GRASS INFUSIONS, Journal of the American Mosquito Control Association, 11(1), 1995, pp. 39-44
Fermented infusions of organic matter are commonly used as baits in tr
aps for gravid female mosquitoes. However, infusions are dynamic, and
their effects on mosquito oviposition as their chemical and microbial
constituents change over time are not well documented. Bermuda grass i
nfusion fermented for periods of 0-63 days was stimulatory to gravid C
ulex quinquefasciatus. In contrast, only 5-25-day-old infusion was sti
mulatory to Culex tarsalis. Standard-aged infusion (7 days old) was as
effective or better than infusion of any other age for Cx. tarsalis,
whereas Cx. guinquefasciatus exhibited a distinct preference for 2-4-w
k-old infusion. The results are discussed in terms of mosquito species
' oviposition site preferences and in terms of mosquito surveillance p
rograms.
