Effect of Common Species of Florida Landscaping Plants on the Efficacy of Attractive Toxic Sugar Baits Against Aedes albopictus.

Attractive toxic sugar bait (ATSB) was applied to 5 different types of commonly found plants in landscaping of northeastern Florida. The ATSB applications were assessed for possible plant effects and preference against Aedes albopictus in semifield evaluations. Positive and negative controls consisted of plants sprayed with attractive sugar bait (no toxicant) and plants with nothing applied.

Attractive Toxic Sugar Bait (ATSB) Mixed With Pyriproxyfen for Control of Larval Aedes albopictus (Diptera: Culicidae) Through Fecal Deposits of Adult Mosquitoes.

Studies were conducted to determine if pyriproxyfen, an insect growth regulator (IGR) added to attractive toxic sugar baits (ATSBs) and ingested by adult Aedes albopictus (Skuse), could be fecally disseminated into water to inhibit emergence of mosquitoes (EI). Experimental treatments consisted of four dilutions of pyriproxyfen (0.5, 1, 5, and 10 ppb) in ATSB, with attractive sugar bait (ASB) serving as the negative control.

Characteristics and Efficacy of Three Commercial Handheld Thermal Foggers with Pyrethroid Insecticides Against Three Species of Mosquitoes.

The field study's objectives were to compare the physical characteristics as well as efficacy with multiple insecticides for Bonide(®) Fog Rx Insect Fogger, Black Flag(®) Propane Insect Fogger, and Burgess(®) Outdoor Propane Insect Fogger. Evaluations were conducted with 7 machine chemical combinations, 3 depths of spray, and 3 species of laboratory-reared mosquitoes, Anopheles quadrimaculatus, Culex quinquefasciatus, and Aedes aegypti. Combinations of these factors were analyzed in conjunction with environmental parameters.

Evaluation of a new spraying machine for barrier treatment and penetration of bifenthrin on vegetation against mosquitoes.

The effectiveness and penetration of a novel, truck-mounted mist sprayer (3WC-30-4P provided by American LongRay) was evaluated with bifenthrin in a large, park-like setting with historic floodwater and woodland mosquito populations. Efficacy evaluations were determined through adult population collections and excised leaf bioassays. Trapping results showed a mean reduction of 77% in mosquito populations in the treated area for 5 sampling events up to 4 wk posttreatment.

Attractive toxic sugar baits mixed with pyriproxyfen sprayed on plants against adult and larval Aedes albopictus (Diptera: Culicidae).

The effect of spraying a mixture of the insect growth regulator (IGR) pyriproxyfen (1 mg/liter) and either 1% boric acid sugar bait or eugenol sugar bait on croton petra plants (Codiaeum variegatum L.) was evaluated against the container-inhabiting mosquito, Aedes albopictus (Skuse). Treatments were applied to plants and evaluated against adult and larval Ae.

Laboratory evaluation of citronella, picaridin, and deet repellents against Psorophora ciliata and Psorophora howardii.

Commercial formulations of 3 repellents: OFF Active (active ingredient [AI] 15% N,N-diethyl-meta-toluamide [deet]), OFF Family Care (AI 5% picaridin), and CVS Pharmacy Fresh Insect Repellent (AI 10% citronella, 2% lauryl sulfate, and 0.2% potassium sorbate) were evaluated to determine the mean protection time provided against the large floodwater mosquitoes, Psorophora ciliata and Ps. howardii.

Evaluation of attractive toxic sugar bait (ATSB)-Barrier for control of vector and nuisance mosquitoes and its effect on non-target organisms in sub-tropical environments in Florida.

The efficacy of attractive toxic sugar baits (ATSB) with the active ingredient eugenol, an Environmental Protection Agency exempt compound, was evaluated against vector and nuisance mosquitoes in both laboratory and field studies. In the laboratory, eugenol combined in attractive sugar bait (ASB) solution provided high levels of mortality for Aedes aegypti, Culex quinquefasciatus, and Anopheles quadrimaculatus. Field studies demonstrated significant control: >70% reduction for Aedes atlanticus, Aedes.
