Mosquitoes are the main vectors for dengue and zika. Insecticides are our best weapon against them.
Australian mosquitoes, unlike their Asian and American counterparts, can still be controlled by insecticides like pyrethroids. What lessons are there for managing pesticide resistance in insects?

Here's how to take the sting out of these harmful pesticides.
Critics fear the merger of agricultural giants Bayer and Monsanto will drive an increase in use of pesticides.
The global food system has been operating in post-truth mode for decades.
Two papers published today report that neonicotinoids have negative effects on honey bees and wild bees in realistic field experiments.
Two large-scale studies confirm that neonicotinoid pesticides can harm bees. But the effects vary widely in different countries, suggesting that calls for a world ban would be premature.
Roll-your-own tobacco contains more additives than factory made cigarettes. So let’s not kid ourselves it’s safer.
Roll-your-own tobacco contains additives to stop it from drying out. So, it's hardly a "natural" or "healthier" alternative to factory made cigarettes.
Three-quarters of Americans don’t eat enough fruits and vegetables.

Reports about trace amounts of pesticides, like the EWG's Dirty Dozen, can leave people afraid to buy fruits and vegetables. But the hype is often overblown.
Soccer player on artificial turf.
Artificial turf has become popular for kids' sports as well as for professional players. The little black crumbs that help support the blades of fake grass may not be so harmless.
The Smarden incident and the arrival of Rachel Carson's Silent Spring in the UK lead people to a new view of the environment.
Fall armyworms have a number of characteristics that make them particularly hard to control. They are strong fliers, can breed at a high rate and also develop quick resistance to pesticides.
The Vespula germanica, or German wasp, is an invasive species in South Africa.

Indigenous biocontrol agents could be used to curb the spread of invasive wasps across South Africa and into sub-Saharan Africa.
Gardening in Australia requires, to varying degrees depending where in the country you are, pesticides, herbicides and fertilisers.
When working with garden chemicals, always make sure you are wearing gloves. Apply sprays and dusts downwind and wear goggles if necessary. Always follow the directions.
The threat of chemical weapon attacks is on the rise globally.
Governments often have limited knowledge of chemical production as it is the preserve of the private sector. Often these facilities are not as well secured as government facilities.
Honeybees aren’t the only wildlife affected by pesticides – wild bees and butterflies also feel the effect.

Two new studies have linked controversial pesticides neonicotinoides to wild bee and butterfly declines.

Advocates have argued for years about whether genetically engineered crops are safe to grow and eat. Plant pathologist and geneticist Pamela Ronald calls for a more nuanced discussion.
New research shows that street lighting changes the activity of moths, and is likely to disrupt nocturnal pollination.

Honey bees, which pollinate many valuable crops, are threatened by parasites, pesticides and development. But selective breeding, more benign pesticides and better nutrition could help turn the tide.
Are genetically engineered crops safe for human health and the environment? A new report says yes but points out problems and regulatory gaps. Three members of the study panel offer their takeaways.
Outbreaks of crown-of-thorns starfish, which eat coral, have been linked to poor water quality.

To fix pollution on the Great Barrier Reef, some farming practices will have to change.
Our modern crops need some help in the immunity department.
Andy / Andrew Fogg
Modern agriculture is synonymous with monoculture. That lack of diversity is bad news for plants' natural immune defenses. Researchers are figuring out how to help plants fend off microbes – without pesticides.
Roundup, or the chemical glyphosate, is a very common herbicide used to kill weeds.
The World Health Organization classifies the common herbicide glyphosate as "probably carcinogenic to humans". But this doesn't mean using it to kill weeds in playgrounds will hurt children.
