A prototype autodissemination station to topically contaminate oviposition‐seeking container‐dwelling mosquitoes with the insect growth regulator, pyriproxyfen, was developed and tested in laboratory. Our test subject Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), an urban species that colonizes small‐volume cryptic larval habitats is a skip ovipositor visits multiple containers. The consists of water reservoir attract gravid females, which joined transfer chamber...
Aedes albopictus, the Asian tiger mosquito, is an aggressive, highly anthropophilic, day-biting mosquito with expanding geographic range. Suppression of Ae. albopictus difficult because abundance and prevalence larval habitats within peridomestic environments, particularly cryptic such as corrugated extension spouts, fence post openings, discarded food containers, etc. Because challenges eliminating or treating this species, we tested autodissemination concept to contaminate these insect...
Background The Asian tiger mosquito, Aedes albopictus, is a vector of dengue, Chikungunya, and Zika viruses. This mosquito inhabits wide range artificial water-holding containers in urban suburban areas making it difficult to control. We tested the hypothesis that female-driven autodissemination an insect growth regulator could penetrate cryptic oviposition habitats treat with conventional insecticidal sprays. Methodology Oviposition preferences Ae. albopictus females for open cups were...
The Asian tiger mosquito, Aedes albopictus, is a highly invasive mosquito species that transmits chikungunya and dengue. This overwinters as diapausing eggs in temperate climates. Early diapause termination may be beneficial strategy for winter control; however, mechanism to terminate the process using chemicals not known. We tested hypothesis hormonal imbalance caused by administration of juvenile hormone analog would egg A. albopictus. insect growth regulator pyriproxyfen on all...
The present study explicitly evaluated the genetic structure of Aedes aegypti Linn, vector dengue, chikungunya, and Zika viruses, across different geo-climatic zones India also elucidated impact ecological topographic factors. After data quality checks removal samples with excess null alleles, final analysis was performed on 589 individual using 10 microsatellite markers. Overall findings this suggested that, Ae . populations are highly diverse moderate differentiation between them. Around...
Variations in the life tables and other biological attributes of four strains Culex quinquefasciatus Say (Diptera: Culicidae) from geographically isolated regions India that had been reared to fifth generation laboratory were assessed under a standardized rearing regime constant conditions. Two arid habitats [Jodhpur (JD) Bikaner (BKN)], one semi-arid inland habitat [Bathinda (BTH)], coastal [Jamnagar (JMN)] standard strain (LAB) compared. Horizontal life-table parameters measured for each...
The Asian tiger mosquito, Aedes albopictus (Skuse), transmits important arboviral diseases and displaces native species. This peridomestic mosquito deposits eggs in natural artificial containers. Container larval habitats tend to be cryptic and, therefore, difficult reach by conventional insecticide treatments. We have developed an autodissemination station that transfers the insect growth regulator, pyriproxyfen, from oviposition sites. Mosquitoes visiting become contaminated with oil...
Abstract BACKGROUND Control of the container‐inhabiting mosquito, Aedes albopictus, is difficult using conventional methods due to its selection cryptic peri‐domestic habitats. We evaluated whether autodissemination stations can deliver sufficient pyriproxyfen sentinel containers produce significant pupal mortality in different habitats such as competing oviposition sites, habitats, junkyards and tire piles. also tested how far pesticide could be transferred over a 200‐m range. RESULTS...
Abstract Effective suppression of container-inhabiting Asian Tiger [Aedes albopictus (Skuse)] (Diptera: Culicidae) and yellow fever aegypti (L.)] mosquitoes presents one the most intractable problems for modern mosquito control. Traditional tools often fail to control populations these species, are prohibitively expensive or have negative environmental impacts. Novel approaches urgently needed integrated management programs. One promising techniques is autodissemination. We present results a...
Pyriproxyfen, a juvenile hormone analog insect growth regulator (IGR), is recommended insecticide for the control of container-inhabiting mosquitoes. The effects eight container substrates (three plastics, wood, tire rubber, clay pot, concrete, and glass) were studied on reduction bio-efficacy pyriproxyfen Aedes albopictus (Skuse) in laboratory. Insect regulator-bioassay third instars showed significant increase LC50 with some compared probably because adsorption to substrate. substrate...
The exposure of sublethal doses (25% emergence inhibition) diflubenzuron (DFB) (0.0002 mg/liter) and azadirachtin (AZD; 0.0079 insect growth regulators was provided to late third–early fourth instars Culex quinquefasciatus till adults find out the effects on various biological life table attributes adults, comparison made with control (CTL) as well. Life expectancy both males females DFB survivors significantly less in AZD CTL ones; however, it nonsignificantly different between AZD. In all...
Variation in egg surface morphology and morphometrics of Culex quinquefasciatus mosquitoes the Jodhpur, Bikaner, Jamnagar, Bathinda strains were correlated with geographical distribution different ecological regions India. We report geographic variation Cx. based on 44 attributes micropylar conical-shaped eggs, including apparatus (corolla, disc, mound), tubercles, exochorionic tubercle, pores, network anterior, middle, posterior regions. No remarkable differences observed eggs these except...
Duet was field evaluated against caged Aedes albopictus, with the use of a truck-mounted ultra-low volume (ULV) cold aerosol sprayer at rate 90.6 ml/ha. Cages were placed in 3 rows stationed 30.5, 61.0, and 91.5 m downwind spray vehicle. Initial knockdown >99% mortality ranging between 95.8% 98.0% across distances. Volume median diameter (VMD) droplet density slightly reduced (16.4% 18.6%, respectively) by distance. Reduction VMD density, however, did not reduce mortality. The ULV...
We constructed an electric multi-rotor autonomous unmanned aerial system (UAS) to perform mosquito control activities. The UAS can be equipped with any of four modules for spraying larvicides, dropping larvicide tablets, spreading granules, and ultra-low volume adulticides. module sprayed 124 μm drops at 591 mL/min over a 14 m swath total application rate 1.6 L/ha. tablet was able repeatedly deliver 40-gram tablets within 1.1 the target site. granular spreader covered 6 treated 0.76 ha in 13...
Mosquito control programs in the United States are still searching for best management practices to Asian tiger mosquito, Aedes albopictus (Skuse; Diptera: Culicidae). Most intervention methods this species either labor intensive (e.g., source reduction) or short-term ultra-low-volume adulticiding). We investigated effectiveness of barrier spray pesticide applications within urban and suburban residential yards New Jersey as a strategy using before-after-control-impact (BACI) approach....
Abstract The ecological variation in biological and adult life‐table attributes of two populations Aedes aegypti (Diptera: Culicidae) from the desert (Jodhpur) coastal (Kolkata) regions India are assessed to understand reproductive survival strategies. results showed that females lived longer than males both strains. strain was more r‐strategist because its higher intrinsic rate increase ( r m = 0.23), finite λ 1.25), lower life expectancy (7.9 days) (14.4 days), mean generation time T 19.2...
