The insect glue, produced from edible oils, was inspired by plants such as sundews that use the strategy to capture their prey. A key advantage of physical pesticides over toxic pesticides is that pests are highly unlikely to evolve resistance, as this would require them to develop much larger and stronger bodies, while bigger beneficial insects, like bees, are not trapped by the drops.
The drops were tested on the western flower thrip, which are known to attack more than 500 species of vegetable, fruit and ornamental crops. More than 60% of the thrips were captured within the two days of the test, and the drops remained sticky for weeks.
Work on the sticky pesticide is continuing, but Dr Thomas Kodger at Wageningen University & Research, in the Netherlands, who is part of the self defence project doing the work, said: “We hope it will have not nearly as disastrous side-effects on the local environment or on accidental poisonings of humans. And the alternatives are much worse, which are potential starvation due to crop loss or the overuse of chemical pesticides, which are a known hazard.”
It’s not because they’re gross, it’s because they eat our food. And we grow monocultures so it’s a perfect breeding ground for pests. Also if you read the article the new pesticide is physical and doesn’t harm large predatory insects.
they help create your food.
No pesticide that physically traps insects is specific to one kind. It’s not really possible. It may not capture bees, but it will capture other smaller insects than thrips that do no harm. For example green lacewing larva.
I’m not fighting you. It’s just you’re acting as if the reason we research pesticides isn’t because we need it to protect our food source.
I’m not even saying that there isn’t some possible alternative, I’m just saying monoculture grains is how humanity gets most of its calories right now. It’s how we currently survive. That requires pesticides. These pesticides are far less damaging to the world than the current ones in use right now. It’s in the research phase too, so it’s not like we’re committing to this specific idea. Everyone knows there are pros and cons, the scientists doing the research do too. You’re not the first person to realise that this will trap all small insects. Just a reminder that our current solution kills all insects and this one is better. The fact it doesn’t harm bees is already a massive improvement.
Everyone should be welcome and encouraged to research any idea that’s better than our current ideas in any way. Any knowledge is good knowledge.
As for your preferred ideas? There are lots of ways to help be part of a future that includes what you feel is the best solution. That being said, none of them include being disingenuous about why we use pesticides in the first place. I don’t know why that was contentious to you. We don’t kill bugs because they’re gross, we kill them because they eat our food.
Fundamentally you misinterpreted what I said. I’m not being disingenuous about why we use pesticides, I’m simply saying we are doing it wrong and should not use any. The whole premise of “we must use pesticides or we’ll starve” is, to put it simply, a fallacy. Because we are no longer producing food so we don’t starve but so that huge corporations can profit more.
The big problems with the “well this is slightly better than the alternative” are: First, the alternatives don’t necessarily kill all insects - they can be highly targeted too. Secondly, killing any beneficials is treading backwards. The more beneficials you kill the more you need things to kill the pests. In other words, it’s pushing “solutions” in completely the wrong direction. And industrial ag pursues this with such fervor it’s accelerating the process to the point where we may have no functional insect populations left. This is an existential threat.
In fact they don’t in the large scheme of things. Or as the joke goes, they only eat a little.
I think this sums up your misinterpretation of what I’m saying and I concede it’s understandable because I was a little obscure in my jest. The “eww gross” line comes from a basic prejudice that people have about insects - that they are always pests and don’t serve an important purpose. And so our approach to pest control has always been one of “insect bad! kill them all!”. Even the fact that if someone finds a bug in their store-bought produce - and I’ve seen this with my own eyes - they are inclined to take it back. That’s the level of ridiculous over-reaction we have when in reality we should be enlisting the help of the insect world.
And I can personally attest this works on a commercial scale.
Using sustainable practices “they only eat a little” is totally valid. The way we farm now… A pest outbreak will ravage a monoculture crop.
I know there are great alternatives, but they all have higher labour requirements. Modern capitalism can’t tolerate that. If we can find a better solution now we can mitigate the damage before we end capitalism. After that we can definitely switch to more labour intensive sustainable practices. I’m not an accelerationist so I’m not rushing to end the current world order before trying to make all the improvements we can.
On #1 - a diversified farm growing “speciality crops” (USDA speak for food we consume directly instead of commodities) will typically have margins >20% and can easily net $25k or more an acre. In commodities, even the highest net for almonds and pistachios might only get you $1.2-1.5k per acre. Many commodities like corn can have a negative margin and only survive through subsidies.
All this matters because farmers have literally been digging their own graves and become little more than share croppers. It’s so hard to be viable direct to consumer there is little choice - a really classic example being chicken production where it’s virtually impossible to be an independent producer because companies like Tyson have made sure all the regulations favor them. So now they’ll loan you the money for facilities you’ll never pay off and you have no choice but to sell to them at whatever price they set.
I like what you’re saying and I agree with it fundamentally. I wish it is possible to have the majority of crops be direct to consumer. I KNOW everyone is happier when they have a real personal relationship with the products they consume. That’s even part of what marketing abuses when it anthropomorphises brands.
I’m personally pessimistic on that front though, I think it can’t happen in modern capitalism for two major reasons. Number one, I don’t think the majority of the population of Western nations, let alone the world, can tolerate even a moderate increase in food prices without creating massive instability. I know what the “middle men” jack up prices considerably on almost everything, but the staples: wheat and meat in my part of the world, simply cannot be sold cheaper by smaller operations than grocery store prices (in part due to the regulatory capture so prevalent in modern capitalism). Number two, of the people that CAN tolerate the increase, I don’t think modern capitalism would allow their profits to be undercut by a significant shift towards small producers selling direct to customers. They have a few tools that I just don’t think most people are prepared to live without like comfort and consistency. I can get plums, cauliflower, tomatoes, broccoli ANYTIME OF YEAR at reasonably consistent prices. The idea that people will have to pay more AND change to seasonal eating habits where they just can’t get certain things most of the year? I think we’re too far into the comfort of bourgeois decadence, excuse my communist language, to tolerate the change.
I will say I have enjoyed this discussion and I certainly agree that I mischaracterised you by initially latching onto a throwaway “ew bugs” comment.
It will harm any insect the same size as the target ones. Insects have so so many ecological benefits, as pollinators, as part of the food chain, as unique and amazing creatures in and of themselves, they may contain chemicals and biological systems we don’t yet understand but that future generations will benefit from the knowledge of. We need to protect our biodiversity.
