Biological control of Anopheles darlingi , Aedes aegypti and Culex quinquefasciatus larvae using shrimps

Abstract

Mosquitoes can act as vectors of important diseases such as malaria, dengue, Zika virus, yellow fever, Chikungunya and Mayaro fever, in addition to filariasis. The use of insecticides, larvicides, bed nets and repellents, besides the use of drugs as chemoprevention and the treatment of the sick are currently the pillars of the control of these vectors. We studied the biological control against of Anopheles darlingi, Aedes aegypti and Culex quinquefasciatus larvae using shrimps of the species M. pantanalense, M. amazonicum, M. brasiliense and M. jelskii. Larvae of mosquitoes were collected from the breeding environment and placed in a 500 and 1000 l tank containing 60 shrimps/m2. The predatory activity was evaluated for 30 days and, in all groups it was observed that 100% of the larvae were consumed in few minutes. In the environment, these same species of crustaceans were released in water bodies with the presence of larvae of these insects. In just 72 h there was a marked reduction of the larvae in the release sites of shrimps. Similarly, there was a reduction in the number of adult mosquitoes caught near the breeding sites, allowing to infer that, in places where the crustaceans were released, the predatory activity on the larvae of mosquitoes was sufficient to reduce the number of adult mosquitoes p ≤ 0,05. This is the first description of the predatory activity of M. pantanalense, M. amazonicum, M. brasiliense and M. jelskii on An. darlingi, A. aegypti and C. quinquefasciatus larvae, constituting an important tool of biological control of these parasites-vectors.

Insecticidal Efficacy of Microbial-Mediated Synthesized Copper Nano-Pesticide against Insect Pests and Non-Target Organisms

“…Mosquito vectors are distributed abundantly in tropical and sub-tropical regions and transmitting several pathogens to humans and animals. They transmit several vector borne diseases including, dengue, malaria, yellow fever, filariasis and recently zika virus [ 1 ]. Malaria is caused by the Plasmodium parasite carried by female Anopheles mosquitoes, filariasis by female Culex and Anopheles mosquitoes while dengue, yellow fever and zika are transmitted by Aedes pp.…”

Innovative Methods of Mosquito Management

“…Both natural enemies of the target mosquitoes and biotoxins are used in biological control tactics. Invertebrate predators, nematodes (such as Romanomermis culicivorax), larvivorous fish (such as Gambusia affinis), some fungi (like Lagenidium giganteum), and protozoa are included in this regard [66].…”

Predation risk effects on larval development and adult life of Aedes aegypti mosquito

“…Studies have demonstrated successful control of Ae. aegypti using a variety of natural predators, including fish (Pamplona et al ., 2004; Cavalcanti et al ., 2007; Becker et al ., 2010), amphibians (Blum et al ., 1997), shrimp (Coelho et al ., 2017), copepods (Marten and Reid, 2007), odonates (Fincke et al ., 1997; Akram and Ali-Khan, 2016), and other aquatic invertebrate species (Becker et al ., 2010; Bellamy and Alto, 2018). Predators can exert these effects either directly via prey reduction from consumption (e.g.…”
