Field Trials of Larvex
AERIAL APPLICATIONS OF LARVEX VS. AE. TAENIORHYNCHUS IN MANGROVE SWAMPS IN THE CAYMAN ISLANDS (M E C GIGLIOLI, MRCU)
A high degree of control (95%) is possible with aerial applications of 7.4Kg a.i./ha Larvex 15 in open water or with 18.5kg a.i./ha for dense mangrove canopy......being "rained" down as a course spray from open ended pipes. Much more cost effective applications may be made using Larvex 100.
MOSQUITO LARVAL CONTROL USING LARVEX MONOLAYER (Blair Research Laboratory, Harare, Zimbabwe)
FIELD TRIALS OF INSOLUBLE MONOLAYERS IN MOSQUITO CONTROL AT AHERO, KENYA, 1972-75. (ANOPHELES GAMBIA)
MRC Kisumu Project
In most of the field experiments the LARVEX monolayer reduced the pupal and 4th stage larval counts by at least 90%, in some cases by 100%, by the day following treatment and in most cases the depletion several days after was 100%, viz.:
(Many ovipositing/emerging adult flies seen to be trapped and wetted on the surface).
