选择合适的灭蚊产品
If you’re involved in selecting the professional mosquito control products used to control nuisance populations and disease vectors, how do you begin to assess and decide what products get put into your program? When it comes to public health mosquito control, there are a lot of options. Here is what we recommend be considered when choosing the right products for mosquito control in your community:
Consider the fundamental approach for your professional mosquito control program. 你是否专注于 积极主动的 population suppression – primarily using larvicides to keep mosquito populations low from the get-go? 还是你倾向于用更 响应 approach, opting to apply adulticides to 减少 population spikes or control disease? An integrated approach supports doing both – using larvicides for preemptive suppression and adulticides to control emerging populations.
回顾项目目标, 财政和人力资源, and your local seasonality for mosquito control can often lead you towards the first important choice in public health mosquito control – larviciding, 通奸或综合控制措施.
Larviciding involves treating the water where mosquitoes lay eggs with insecticides to prevent larvae from becoming flying and biting adults. Think of it as stealth mosquito control – it works 积极主动的ly behind the scenes, 对你的整体计划有很大的好处. At first glance, the upfront cost of larvicide products can appear to be prohibitive. 但如果使用得当，杀幼虫实际上会 减少 the amount of adulticide treatments needed to deliver and maintain nuisance and disease control in your district or county.
Early in the season, population suppression using larvicides is typically most effective. Breeding habitats – and their ease of access for treatment – are often important factors in product selection for larvicides. 但是到了中后期, combating disease vectors and population spikes with adulticides may become more impactful.
There are three main active ingredients available in larval control products for public health mosquito control.
Mosquito adulticides are applied through an Ultra-Low-Volume (ULV) sprayer that typically puts out less than 1 oz of product per land acre. 除了经济, adulticides allow you to act fast and deliver immediate relief against nuisance or disease vectors. 当你的选民要求迅速采取行动时, an adulticide treatment is a very visible and politically “immediate” way to show you’re taking public health seriously. 另一方面, adulticide treatments may face public push back from residents, on a wide range of issues from the impact of a treatment on the environment, 与农药接触有关的人类风险, 以及介于两者之间的一切. So, know your constituents and be prepared to address application safety.
When it comes to using any control product in your program, what do you know about how susceptible your local mosquito populations are to that product? 这更具体地适用于杀虫产品. 为什么?
Although there are many adulticide formulations available for public health mosquito control, they only fall into one of two approved classes of chemistry – organophosphates or pyrethroids. So its best practice to rotate between these two chemistry classes to prevent developing susceptibility issues and extend the life of all available products. But the reality is that many parts of the country (and world) are already experiencing very real susceptibility challenges with pyrethroid-based products, which are also widely used in agricultural and pest control applications, 还有蚊虫控制.
While there is a race to find a new class of chemistry for public health mosquito control products, we have to steward the two classes of chemistry we have wisely! Having field trial data or indicator results from bottle bioassay tests that show the susceptibility levels inside your district or county can go a long way in making wise product selections for mosquito control.
