Pests

Although the gel of the aloe vera plant is used to treat sunburn, moisturize skin and boost gut health, its peels are usually discarded. New research now suggests that those peels could also be used, to make non-toxic insecticide for use by farmers.

Just like their field-dwelling counterparts, plants grown in greenhouses are preyed upon by flying insects. The Dutch-designed PATS system is designed to help, by sending tiny drones to chop those insects up in mid-air.

The spotted lanternfly is a serious invasive pest, causing considerable damage to crops such as apples, grapes and hops. That's why it's important to destroy the insect's eggs – which is exactly what the TartanPest robot is designed to do.

It's a sad fact that even though bees are essential to pollinating crops, they're also harmed by the pesticides used on those very same plants. Thanks to a new discovery, however, a bee-friendly pesticide could soon be cheaper and easier to produce.

It would certainly be logical to think that plants don't do well when exposed to forest fire smoke. New research, however, suggests that certain crops get hardier and more disease-resistant when liquid smoke is added to the soil.

It is believed that parasitic varroa mites may be one of the main causes of colony collapse disorder, which is decimating honeybee colonies. There may be hope, however, as a new chemical has been found to eradicate the mites without harming the bees.

Instead of using insecticides, farmers will sometimes cover their plants with a mesh fabric. A new such material has now been developed, which keeps out a wider range of bugs while still allowing crops to get enough sunlight and water.

In East Africa and other regions, potato crops are currently threatened by a worm known as the potato cyst nematode. There could be new hope for protecting the plants, however, in the form of biodegradable paper made from banana waste.

Tiki Brand shifts gears from the torches nearly synonymous with its name and strings up a full strand of outdoor lights complete with silent, odorless mosquito repellent diffusers. The lights create a warming ambiance while fighting off pests.

If farmers know what sort of pest insects are present in their crops – and in what numbers – they can avoid excessive use of pesticides. The FarmSense system was created to provide that information, via a network of Smart Traps.

Although insects may ruin crops, the use of traditional pesticides can definitely harm the environment. Spanish scientists have now developed a possible alternative to those chemicals, in the form of plants that produce insect-confusing pheromones.

Research has found a common pesticide may promote obesity by slowing the calorie-burning ability of certain fat cells. The animal study indicates chlorpyrifos, to be banned in the US, promotes food intake and suppresses thermogenesis in brown fat.
