“…It was noted by Christophers (1960) that the clypeal terminates at the preclypeus. Schaper and Hernández‐Chavarría (2006) say that the anteromedial palatal brush filaments end in a structure that looks like a rake and has four or five large teeth. This structure is at an angle of about 90° to the more complicated arrangement of the setae on the lateral brushes.…”

Aedes albopictus is a vector of numerous viruses in tropical and subtropical regions worldwide, including encephalitis and dengue fever. Although the identification keys depend exclusively on the characteristics of the fourth larval instar, the studies were carried out using scanning electron microscopy (SEM) on the morphology of Ae. albopictus are still insufficient, and more research is required. Therefore, the purpose of this study was to present a comprehensive description of Ae. albopictus mosquitoes based on the morphological features of their fourth‐instar larvae to distinguish them from other mosquito species. Antennae, feeding mouth brushes, mandibles, maxillae, labia, comb scales, anal papillae, siphon, respiratory spiracles, and pecten teeth were among the morphological features specifically described using SEM. The sensilla trichoidea and the sensilla basiconica are the sensory spicules found on the antennal integument. The labrum is a tessellated membrane with two movable brushes on the sides and one middle brush. The mandibles have four sellar setae on the anterolateral side, and the maxillae, which have a thumb‐like structure and a palp located laterally and about four‐fifths of the way from the maxillary brush base to the maxillary notch, are the articulating appendages. On the apex of the palp, there are five sensilla. The eighth abdominal segment is a tiny pentagonal structure with 12 comb scales laterally and a respiratory siphon dorsally. The siphon has two rows of pectin teeth, with 12 teeth per row. Four pairs of siphonal tufts and five perispiracular lobes surround the respiratory spiracles. The anal segment has four anal papillae, a ventral brush, a dorsal brush, and an incomplete saddle. The findings demonstrate that the fourth‐instar larvae of Ae. albopictus have distinctive morphological features, which are crucial for understanding their key characteristics and identifying them, preventing inaccurate identification, and facilitating the control of diseases transmitted by the mosquito vector.Research Highlights A detailed description of various taxonomical interest structures for the fourth‐instar larvae of Aedes albopictus is included in this study. Scanning electron microscopy is considered a helpful technique for identifying Ae. albopictus larvae in their fourth instar.

Predators as Control Agents of Mosquito Larvae in Micro-Reservoirs (Review)

2022

View full text Add to dashboard Cite

The article reviews predators that are able to control populations of mosquito larvae (Culicidae) in phytotelmata and their anthropogenic analogs. The spectrum of mosquito larva consumers in micro-reservoirs is listed. It includes flatworms, crustaceans, arachnids, insects, vertebrates, and carnivorous plants. The biology and practical use of the two most effective biological control agents, predatory mosquitoes Toxorhynchites and copepods, are considered in more detail. Prospects of invertebrate predators as controlling agents for the mosquito larvae in micro-reservoirs in temperate climate zones are briefly discussed.

Prevention and Control Strategies to Counter Zika Virus, a Special Focus on Intervention Approaches against Vector Mosquitoes—Current Updates

et al. 2018

View full text Add to dashboard Cite

Zika virus (ZIKV) is the most recent intruder that acquired the status of global threat creating panic and frightening situation to public owing to its rapid spread, attaining higher virulence and causing complex clinical manifestations including microcephaly in newborns and Guillain Barré Syndrome. Alike other flaviviruses, the principal mode of ZIKV transmission is by mosquitoes. Advances in research have provided reliable diagnostics for detecting ZIKV infection, while several drug/therapeutic targets and vaccine candidates have been identified recently. Despite these progresses, currently there is neither any effective drug nor any vaccine available against ZIKV. Under such circumstances and to tackle the problem at large, control measures of which mosquito population control need to be strengthened following appropriate mechanical, chemical, biological and genetic control measures. Apart from this, several other known modes of ZIKV transmission which have gained importance in recent past such as intrauterine, sexual intercourse, and blood-borne spread need to be checked and kept under control by adopting appropriate precautions and utmost care during sexual intercourse, blood transfusion and organ transplantation. The virus inactivation by pasteurization, detergents, chemicals, and filtration can effectively reduce viral load in plasma-derived medicinal products. Added to this, strengthening of the surveillance and monitoring of ZIKV as well as avoiding travel to Zika infected areas would aid in keeping viral infection under check. Here, we discuss the salient advances in the prevention and control strategies to combat ZIKV with a focus on highlighting various intervention approaches against the vector mosquitoes of this viral pathogen along with presenting an overview regarding human intervention measures to counter other modes of ZIKV transmission and spread. Additionally, owing to the success of vaccines for a number of infections globally, a separate section dealing with advances in ZIKV vaccines and transmission blocking vaccines has also been included.
