Abstract

A Toxic Sugar Bait (TSB, active ingredient 1% boric acid) was evaluated against Aedes taeniorhynchus (Diptera: Culicidae) in the laboratory and the field at St. Augustine, Florida. The laboratory component was comprised of plants located in known Ae. taeniorhynchus resting areas, i.e., black mangrove (Avecennia germinans L.) and yaupon holly (Ilex vomitoria Ait.). The results indicated that TSB sprayed on black mangrove and yaupon holly cuttings at 48 h resulted in significant mortality of resting Ae. taeniorhynchus, compared with the mortality of mosquitoes in the control group under the laboratory conditions. Also, the field studies indicated a significant reduction in mosquito populations after TSB was applied on plants.

 

Un Cebo Tóxico de Azúcar (CTA, ingrediente activo el ácido bórico al 1%) fue evaluado contra Aedes taeniorhynchus (Diptera: Culicidae) en el laboratorio y el campo en St. Augustine, Florida. El componente de laboratorio consistía de plantas ubicadas en áreas conocidas donde Ae. taeniorhynchus reposa, como en mangle negro (Avecennia germinans L.) y acebo yaupon (Ilex vomitoria Ait.). Los resultados indicaron que el CTA rociado sobre recortes de mangle negro y el acebo yaupon a las 48 horas resultó en una mortalidad significativa de Ae. Taeniorhynchus en descanso, en comparación con la mortalidad de los mosquitos en el grupo control en las condiciones de laboratorio. Además, los estudios de campo indicaron una reducción significativa de las poblaciones de mosquitos después de la aplicacióon de CTA sobre las plantas.
