Control of Larval Aedes aegypti (Diptera: Culicidae) by Cyclopoid Copepods in Peridomestic Breeding Containers

Abstract

Mesocyclops longisetus (Thiébaud), Mesocyclops thermocyclopoides Harada, Mesocyclops venezolanus Dussart, and Macrocyclops albidus (Jurine) were tested for their effectiveness in controlling Aedes aegypti (L.) larvae in a variety of containers around homes in El Progreso, Honduras. All four cyclopoid species killed > 20 larvae per cyclopoid per d under container conditions. M. longisetus was most effective, not only because it was the most voracious predator, but also because it survived best in the containers. M. longisetus maintained long-term populations in 200-liter drums, tires, vases, and cement tanks (without drains), providing the cyclopoids were not dried or poured out. M. longisetus reduced third- and fourth-instar Ae. aegypti larvae by > 98% compared with control containers without cyclopoids. M. longisetus should be of practical value for community-based Ae. aegypti control if appropriate attention is directed to maintaining it in containers after introduction.

Toxicity effect of Delonix elata (Yellow Gulmohr) and predatory efficiency of Copepod, Mesocyclops aspericornis for the control of dengue vector, Aedes aegypti

“…If the food supply in a container is poor, the best strategy is to add a small quantity of leaves or grain, and possibly the container with protozoa, to stimulate food production for the copepods. Copepods may fail to establish large numbers and eventually die out in containers (e.g., flower vases, tires, or cement tanks) if the container is so clean that it provides little food [35,36] .…”

Control of aedes vectors of dengue in three provinces of Vietnam by use of Mesocyclops (Copepoda) and community-based methods validated by entomologic, clinical, and serological surveillance.

“…They were also questioned about mosquito recognition, biology, and behavior (questions 5-9), the acceptability of various control options, including Mesocyclops (questions [10][11][12][13][14], and the value of different forms of information (question 15).…”

Comparative Evaluation of Fecundity and Survivorship of Six Copepod (Copepoda: Cyclopidae) Species, In Relation to Selection of Candidate Biological Control Agents Against Aedes aegypti

“…Several species of cyclopoids have been used singly (Lardeux 1992, Marten et al 1994, Torres-Estrada et al 2001 or as mixtures of species found to preexist in water storage containers or natural pools (Marten et al 1989, but up until now, the decision about the selection of appropriate candidates has been made in the absence of definitive knowledge of the reproductive potential and longevity of these species.…”
