Study finds mosquitoes can remember their favorite targets

Researchers from Virginia Tech have gained insights into the likes and dislikes of Aedes aegypti mosquitoes. 

According to their study, the pesky and sometimes dangerous insects remember their favorite targets but can also be trained to stay away from them. 

The team found that dopamine plays a large role in the former, with mosquitoes’ tiny brains showing neural activity in the portion that processes smells and an increase in dopamine, which makes scents easier to distinguish and potentially learn.

9 Foods That Make You Tastier to Mosquitoes

Learn which 9 foods make you more appetizing to mosquitos!

Beer

What’s a cookout without a cold one (or two)? There’s always a cooler full to the brim with ice-cold beers at backyard barbeques. A few Heinekens can give you a buzz, but even a single beer can make you a target for mosquitos. Scientists are not exactly sure why mosquitos go for beer drinkers, but they don’t think it has anything to do with the increase in ethanol in the bloodstream or the heightened body temperature caused by beer consumption. Like us humans, mosquitos may just like the taste of a good brew.

Potassium-rich foods

Bloodsucking mosquitos are extremely attracted to lactic acid. Too bad lactic acid is constantly naturally released by our bodies, making us prime snacks. Eating potassium-rich foods, however, increases the amount of lactic acid you give off through your skin. Bananas, potatoes, prunes, raisins, lima beans, avocados, and spinach are full of potassium, so snacking on these makes you even tastier to the invasive insects. Well, there goes guacamole!

Salty Snacks

Wiping salty potato chip crumbs on bright beach towels or on denim cutoffs while enjoying the sun is a typical summertime occurrence. Little did you know, eating a high-sodium diet also increases the amount of lactic acid you produce, and more lactic acid means more mosquito bites. Filling up on salty snacks like crispy chips, hot curly fries, roasted peanuts, or even that bacon on your burger, will make you that much more delicious to mosquitos.

Sweets

Often picnic tables are piled high with tart cherry pies, melty ice cream cakes and sugary candies to celebrate summer. As much as we love these tasty desserts and sweet things, they have a saccharine aroma that is very attractive to most animals, mosquitos included. Not only will the sweets attract sweet–toothed friends and family, they will also act as magnets for bugs and mosquitos.

Alcohol

A refreshing cocktail or mixed drink will definitely cool you down at an outdoor gathering, but scientists think those who drink alcohol are more likely to attract mosquitos. Not only are they sweet-smelling beverages, the alcohol increases your body temperature, which makes you a target for the little blood-suckers because they are drawn to people with warmer blood. A frozen daiquiri or white sangria sounds super good — until a pesky mosquito bites you.

High Cholesterol

High cholesterol is not only a health hazard, but having a higher level of cholesterol in your blood increases your appeal to mosquitos. It is always important to lower your bad cholesterol if it is too high and recommended by your doctor. Eating more fruits and veggies, and opting for lean meats can help to lower cholesterol levels. Just think of it as killing two birds with one stone.

Limburger Cheese

Chomping on Limburger cheese will transform you into a gigantic neon “Eat Me” sign for mosquitos. This variety of cheese is made with the same bacteria that cause feet to stink. This is a super bonus for mosquitos because they love smelly feet. Well that stinks!

Pickled Vegetables

Picture a perfectly charred hot dog crowned with a heavy dose of tangy sauerkraut, tasty ketchup, and sweet pickle relish. But that sauerkraut and pickle relish can be your downfall. Pickled veggies contain lactic acid, therefore they attract those dreaded mosquitos. Kimchi is another condiment that makes human blood a little sweeter to mosquitos. Maybe a bare hot dog doesn’t taste as bad as itchy bites feel.

Dairy Products

So many delectable summer favorites, like sweet strawberry ice cream, coconut froyo, delicious Redi-Whip, and layered parfaits, are dairy-based. Unfortunately, these desserts and other dairy goods cause the body to produce lactic acid, which reels in the mosquitos. Guess that means we’ll have eat our ice cream inside to avoid those biting bugs.

While that is distressing news for those who happen to fit the aroma profile mosquitoes prefer, there is hope. 

Researchers also discovered that repeated deterrents like swatting and other defensive behaviors resulted in the mosquitoes finding another target, even if it isn’t as tempting.

Exactly which aromas tend to most excite and motivate the insects remains unknown, but the team believes they have embarked upon a path that could lead to more efficient means of mosquito control. 

“For example, we could target mosquitoes’ ability to learn and either impair it or exploit it to our advantage,” Clément Vinauger, one of the scientists, commented.
