“…If late-stage larvae or pupae were present, this was considered evidence of a control failure and the basin scored as ''fail'' since late-stage larvae and pupae would have been exposed to the larvicides' active ingredients in the catch basin for several days and should not have survived. A similar pass/fail criterion for evaluating control effectiveness was used previously to characterize larvicide performance in catch basins Novak 1997, 1999;Nasci et al 2017).…”

“…Based on previous studies using the same or similar larvicide products in catch basins Novak 1997, 1999;Harbison et al 2015Harbison et al , 2016Nasci et al 2017) it appears that 100% control effectiveness is an unrealistic expectation for many areas. Therefore, to compare effectiveness across the larvicides evaluated, a threshold of 25% or more of the basins scoring ''fail'' in a given site (cluster of catch basins) was set.…”

“…In 2017, the NSMAD performed district-wide quality control evaluations of applied catch basin larvicides throughout the season. The district-wide protocol is described by Nasci et al (2017). Briefly, to evaluate basins treated with bacterial larvicides, 20 catch basins are sampled within 1-mi 2 (2.6-km 2 ) treatment areas at specified durations postapplication with 2 dips of a standard 350-ml dipper.…”

“…In addition, 94 VectoLex FG-treated basins from an area known to have some of the most productive basins in the district (Nasci et al, 2017) were monitored weekly using the same pass/fail criterion. None of these 94 basins were included in the districtwide quality control inspections.…”

, 7 mosquito control programs in the midwestern United States evaluated a total of 9 catch basin larvicide formulations using similar protocols. Treated basins were monitored among study sites to observe when larvicides failed to control mosquitoes in 25% or more basins within a site. Overall, when monitoring occurred within the maximum label duration of the larvicides, sites treated with a single larvicide tablet or briquet surpassed the 25% fail threshold more often than pellet and granular larvicide formulations. In 438 of the study basins, the depth from sump bottom to catch basin lid was measured. In basins that were deeper than 5 ft (1.5 m), larvicides failed to control mosquitoes significantly more often than those 5 ft or shallower.

“…Over many decades, few species of mosquitoes that intimidated the public and veterinary health have emerged o0r re-emerged in Africa (Ahmed and Matsumura, 2012;Ahmed and Vogel 2016a,b,c;Mweya et al, 2017). Culex pipiens is considered one of the most critical species that threaten and transmitted numerous diseases as a vector for instance, West Nile virus, Bancroftian filariasis, Rift valley fever virus, Usutu virus, and avian malaria (Ahmed and Matsumura, 2012;Mohamed et al, 2016;Ahmed and saba, 2016;Nasci et al, 2017). However, Culex pipiens control is considered a paramount (Badawy et al, 2017;Brustolin et al, 2017;Tmimi et al, 2018).…”

Synergistic action of glyphosate on novel pesticides against Culex pipiens L. (Diptera: Culicidae) mosquitoes under laboratory conditions

The recognition of how glyphosate affect mosquito ecology and behavior is limited. Thus, in this study, we evaluated the toxicity of six selected pesticides plus combination with glyphosate on 4 th instar larvae of Culex pipiens after 24, 48, and 72-h exposure. As a result, Sulfoxaflor + spinetoram and abamectin were the most toxic pesticides (LC50 was 0.084 and 0.088 ng/ml after 24-h exposure, respectively). After 48-h exposure, emamectin benzoate was the most powerful pesticide (LC50 was 0.0036 ng/ml), while sulfoxaflor + spinetoram, abamectin, and spinosad were the modest pesticides. Further, imidacloprid was the lowest toxic pesticide (LC50 was 5.57 ng/ml). However, similar trend was achieved after 72-h exposure. In combination with glyphosate, it significantly synergized the selected pesticides except spinosad and emamectin benzoate after 24-h exposure. After 48 and 72-h exposure, glyphosate synergized significantly most of the selected pesticides except spinosad (LC50 was 0.052 and 0.01 while synergistic ratio (SR) was 0.38 and 0.30 after 48 and 72-h exposure, respectively). Based on the LT50 values, emamectin benzoate and abamectin demonstrated high efficiency against Culex pipiens (42.60 and 43.61 hours), and imidacloprid was the least effective (232.08 hours). Whereby, in the combination with glyphosate, sulfoxaflor + spinetoram and emamectin benzoate revealed the high potency against Culex pipiens (39.16 and 43.77 hours), and imidacloprid remain with the same trend of efficacy as lowest effective selected pesticide towards Culex pipiens (563.30 hours). Further biochemical and molecular biological experiments needs to be done for better understanding of the mechanism of glyphosate on Culex pipiens mosquito.

The control of medically important container-inhabiting mosquitoes is an ongoing challenge for mosquito control operations. Truck-mounted application equipment is a common option for rapid areawide larvicide deployment utilized by mosquito control operations. We tested the effectiveness of two truck-mounted sprayers (A1 Super Duty + Buffalo Turbine CSM3), for the deployment of water-dispersible biopesticides (VectoBac WDG:VectoLex WDG 50:50). Sixty residences within four residential neighborhoods in New Jersey were treated in 2019 and 2020. Three empty bioassay cups were placed in specific locations on each property (front yard/ back yard/ side of house), with an additional cup placed in an adjacent catch basin. This approach was replicated in two untreated control neighborhoods. Following larvicide application, cups were subjected to bioassays wherein larval mortality was tracked through adult eclosion. Overall, average larval mortality rates were 56% higher in treated cups compared against untreated controls. Mortality rates were affected by cup location, with 39% mortality in bioassay cups from back yards, 54% in those from the sides of houses, 73% in front yards, and 76% from cups in catch basins. Mortality did not differ significantly between the four treated neighborhoods, nor by the type of sprayer used. Our research shows that truck-mounted sprayers can be an effective method for larvicide deployment in residential neighborhoods, but effectiveness may depend upon the location of the target treatment area in relation to residences and other geographic obstacles.
