“…The use of fungus impregnated black cotton cloths has been shown to be effective at reducing adult Aedes survival under field conditions when tested in large cages [4,8]. Other delivery systems, such as impregnating clay water storage pots with fungal spores [11] that mosquitoes are attracted to as resting sites, or applying fungi to house screens, such as eave curtains, could also be promising delivery tools for infecting mosquitoes that come into contact with these screens during host seeking behaviour [12]. …”

BackgroundEntomopathogenic fungi could be useful tools for reducing populations of the dengue mosquito Aedes aegypti. Here the efficiency of fungus (Metarhizium anisopliae) impregnated cloths (with and without imidacloprid [IMI]) was evaluated against adult A. aegypti in simulated human dwellings. Behaviour of mosquitoes in the presence of black cloths was also investigated.FindingsWhen mosquitoes were released into the test rooms, the lowest survival rates (38%) were seen when five black cloths impregnated with conidia of ESALQ 818 + 10 ppm IMI were fixed under tables and chairs. This result was significantly lower than the survival rate recorded when cloths were impregnated with ESALQ 818 alone (44%) or ESALQ 818 + 0.1 ppm IMI (43%). Blood fed A. aegypti had lower landing frequencies on black cloths than sucrose fed insects during the first 24 h following feeding, which may have been due to reduced flight activity. Few mosquitoes (4-5%) were observed to land on the cloths during the hours of darkness. The landing pattern of sucrose-fed mosquitoes on non-treated and fungus-treated cloths was similar.ConclusionThe synergism between M. anisopliae and IMI significantly reduced Aedes survival in simulated field conditions. The use of fungus impregnated cloths is a promising point source application method for the control of adult A. aegypti.

“…These results demonstrate that choice of substrate is important in both bioassay design and end product development. Studies exploring transfer of conidia to mosquitoes following short-term residual exposure also show substrate type to effect infection levels and spore persistence (Farenhorst et al, 2011).…”

“…35 As mosquitoes pass through the eaves of houses when attempting to find their human hosts, fungus applied to eave curtains could also be effective for the infection of adults. 36 Our group has concentrated on the use of small black cotton cloths (∼8×6 cm) impregnated with conidia as a potential delivery system for use in intra-and extra-domicile situations. This is a simple delivery system for biological control of adult mosquitoes, directed at their known behavioral preferences for resting/landing on dark surfaces.…”

Recently, advances have been made in the use of entomopathogenic fungi for the control of not only crop pests but also disease vectoring insects. New approaches, for example, combining control strategies such as the application of conventional insecticides and biological control agents together, are highly promising, especially as many insecticides are compatible with entomopathogenic fungi. In this review, we discuss some of the new approaches being developed for vector control. Governmental authorities must implement rational integrated vector management programs for reducing deaths and suffering caused by insect-vectored diseases. Although there are now many alternatives to conventional chemical control methods, the use of pesticides is still the mainstay of mosquito control measures. However, mosquitoes are rapidly developing resistance to the chemical insecticides in use at the moment. The deployment of entomopathogenic fungi for the control of all stages of the mosquito life cycle is an alternative strategy currently being investigated by many different research groups. It has been shown that entomopathogenic fungi can efficiently kill mosquito larvae and adults in laboratory and field conditions. However, an important aspect of this new approach is how to apply these biological control agents economically and efficiently. By using combinations of control agents and novel application systems, it may be possible to significantly reduce mosquito populations to levels at which epidemics of malaria, dengue fever, zika virus, and chikungunya do not occur.
