Efficacy of a mermithid nematode Romanomermis iyengari (Welch) (Nematoda: Mermithidae) in controlling tree hole-breeding mosquito Aedes albopictus (Skuse) (Diptera: Culicidae) in a rubber plantation area of Kerala, India
In rubber plantations, tree holes are one of the major types of breeding habitats of Aedes mosquitoes which transmit dengue and chikungunya. A mermithid nematode, Romanomermis iyengari , was evaluated in tree holes for its efficacy in controlling Aedes albopictus . Infection of mosquito larvae by th...

| description | In rubber plantations, tree holes are one of the major types of breeding habitats of
Aedes
mosquitoes which transmit dengue and chikungunya. A mermithid nematode,
Romanomermis iyengari
, was evaluated in tree holes for its efficacy in controlling
Aedes albopictus
. Infection of mosquito larvae by the nematode was determined through microscopic examination on the next day of application, and evaluation of immature density of mosquito was done on the seventh day. After application of the infective stage of the nematode in a host–parasite ratio of 1:3 or 1:4, the infection rates on the different larval instars of mosquito were similar, 85.7–95.8 % in first to third instars and 79.3 % in fourth instar larvae or 100 and 92.9 %, respectively. Parasite burden varied from 1.1 to 2.4, respectively, among first and third instar larvae applied at 1:3. At 1:4, the parasite burden was between 1.6 (fourth instar) and 4 (second instar). The increase in parasite burden due to parasite density was significant in all the larval instars (
