Male medflies that are genetically altered using the RIDL technique don't produce viable f...

Mediterranean fruit flies are responsible for extensive damage to fruit and vegetable crops, not only in the Mediterranean region but also in Australia, North and South America. While existing methods of controlling them include the use of insecticides and sterilization, the University of East Anglia and biotech company Oxitec are pioneering what they claim is a greener and less expensive approach – they're genetically modifying male fruit flies to produce only male viable offspring.  Read More

Methods for controlling mosquitoes usually take two tacks: luring the mosquitoes into a trap away from humans, or discouraging them from biting at the source. Both methods can be expensive, unhealthy, cumbersome, or disgusting (the smell of rancid butter, anyone?) and generally aren’t scalable for the countries that suffer the most from mosquito-borne disease. New research explores how a mosquito’s neurons actually detect humans, and presents a promising class of chemicals, screened for safety, cost, and an appealing scent, some of which attract mosquitoes and others of which mask the smell of tasty human skin.  Read More

Researchers have discovered which receptors mosquitoes use to detect DEET (Photo: Shutters...

Nothing keeps the mosquitoes away quite as well as DEET, but it's not the most innocuous of substances – besides stinking, it also melts plastic and synthetic fabrics, plus it's even been linked to problems in users' central nervous systems. It can also be prohibitively expensive for use in developing nations. Thanks to research being conducted at the University of California, Riverside, however, a new generation of non-toxic but highly-effective repellants may be on its way.  Read More

A Colorado potato beetle tries to find purchase on one of the slippery surfaces

Not having air conditioning in my house, here's something I didn't know: the inner surfaces of air conditioner ventilation pipes are often covered in cockroaches. Nice. In order to keep the roaches out of those pipes – along with keeping other insects out of other places – scientists from Germany's University of Freiburg have developed new bio-inspired surface coatings that even sticky-footed bugs can't cling to.  Read More

It's summertime in the Northern Hemisphere, and that means the bugs are out – specifically, ticks. In light of the ensuing infestation, otherwise known as the annual repopulation, three professors at the Virginia Military Institute (VMI) have crossed the business of pest control with the world of robotics by last month testing their robotic "tick rover" to determine its efficiency at removing the blood suckers from the yard.  Read More

It has long been believed that detecting carbon dioxide was one of the ways that mosquitoes target their human prey. But the fact that mosquitoes tend to favor certain people over others indicates that some other odor also plays a part in the attraction. Researchers at the Howard Hughes Medical Institute (HHMI) have genetically engineered mosquitoes to alter their sense of smell, which could provide the understanding required to block the pesky pests' attraction to humans.  Read More

We recently took a look at the InaTrap insect trap that lures insects into its designer-inspired form to quietly and efficiently send them to an early grave. But if you’re looking for something slightly more badass that provides a greater sense of satisfaction when taking out those pesky bugs then it’s hard to go past the Bug-A-Salt. The brainchild of Santa Monica-based artist Lorenzo Maggiore, the Bug-A-Salt is a pump action gun that takes out pests in a blast of non-toxic table salt.  Read More

The InaTrap insect killer lures insects using an intermittent light and photocatalyst reac...

We know there’s an ongoing quest to build a better mousetrap, but what about a better insect trap? That’s just what Acase, working with design house inadays, believes it has done with the creation of the InaTrap. With an appearance not dissimilar to a designer lamp, the InaTrap attracts, traps and kills insects so you can ditch the swatter and insect spray.  Read More

Scientists have created genetically-modified mosquitoes that are incapable of spreading ma...

Last year, Prof. Anthony James announced that he and his colleagues had genetically altered Aedes aegypti mosquitoes in a fashion that could drastically reduce their populations. In a nutshell, the altered genes cause the female mosquitoes to be born without wings – this makes it rather difficult for them to go foraging for blood, and turns them into easy prey for almost any predator. The non-biting males are born with wings, and subsequently go off and mate with unmodified females, passing the modified genes along to their offspring. Now, James has done some more genetic engineering, to create mosquitoes that can’t spread malaria.  Read More

The NANOMOSKI process utilizes silica nanoparticles to render clothing mosquito-repellant

For many of us, mosquitoes are an irritating pest that can ruin any number of outdoor activities. For many others, however, they are also spreaders of malaria – a disease which infected approximately 216 million people in 2010, according to an estimate by the World Health Organization. Repeatedly slathering on bug repellant is one way of dealing with the insects, although wearing clothing made from mosquito-repellant fabric sounds a lot more preferable. While existing mozzie-unfriendly garments have some limitations, Portuguese tech company Nanolabel has developed a new treatment process that it claims is far superior to traditional technology.  Read More
