Insects cultivate 'antibiotic-producing bacteria' in their antennae
Bacteria live in, on and around us and other organisms with sometimes very beneficial results. For the first time scientists have shown that one species of insect deliberately cultivates bacteria in its antennae in order to protect their larvae from fungal attack. This highly specialised interaction between an insect species and bacteria protects the insect's offspring against microorganisms which might infect it during its cocoon stage. (2007-03-31)

Allergic to insect stings: Allergy shots decrease anxiety and depression
According to a study being presented at the American College of Allergy, Asthma and Immunology Annual Scientific Meeting in Baltimore, Nov. 7-11, allergy shots, also known as immunotherapy, can improve quality of life for insect sting allergy sufferers. (2013-11-08)

Australian Magpie 'dunks' its food before eating, researchers find
Scientists at the University of York, in collaboration with researchers at Western Sydney University, have shown that the Australian Magpie may 'dunk' its food in water before eating, a process that appears to be 'copied' by its offspring. (2017-09-07)

Cycad plant depends on insect for multiple services
When a plant endemic to several islands in the Western Pacific Ocean taps the services of a helpful insect, a double-dose of benefits comes its way. The plant is a member of a unique group of plants known as cycads, which produce their seeds in cones rather than within fruits. The insect is a tiny moth currently known to exist only on the islands of Guam and Rota. (2010-06-08)

Distant attraction
An article in Ecology Letters reports chemical stimulus from galls change plant morphology and physiology. Previous studies could not determine whether galls are induced by mechanical or chemical stimuli because feeding and oviposition occurred at the site of gall formation. This study shows effects of chemical stimuli separated from mechanical influence of probing stylets or ovipositors. It suggests galls induced by a chemical stimulus transport to buds via vascular tissue and its efficacy is dose-dependent. (2003-01-29)

Global changes in insect populations reflect both decline and growth
The widely reported 'insect apocalypse' is far more nuanced than previous studies have suggested, according to a new study, which reports the findings of a meta-analysis featuring data from 166 long-term surveys across 1,676 sites worldwide. (2020-04-23)

Plant diversity increases insect diversity
The more plant species live in grasslands and forests, the more insect species find a habitat there. However, the presence of more plant species does not only increase the number of insect species, but also the number of insect individuals. Simultaneously, animal diversity is not only determined by plant diversity, but also by the physical structure of the plant communities. These results have consequences for the insect-friendly management of grasslands and forests. (2019-04-08)

Smithsonian scientists use DNA to quickly unravel relationship between plants and insects
It can take years of direct observation for a researcher to fully understand the diets of a community of herbivorous insects in a tropical rain forest. Now, five Smithsonian scientists are paving a fast track using the DNA found inside the insects' stomachs, potentially turning years of research into months. This method will help scientists understand the ecology and evolution of plant-herbivore interactions more efficiently. (2013-03-25)

When scientists play with LEGO: A new creative version of pinned insect manipulator

(2010-08-25)

Insects' ability to smell is phenomenally diverse, a new protein structure hints at how
Even though they don't have conventional noses, insects have adapted to smell odors in nearly every imaginable niche. Mosquitoes find us by our odor molecules binding to odor receptors on their antennae, bees are drawn to flowers the same way, whereas ticks detect an approaching host using receptors on their forelegs. (2020-02-15)

Could Bt transgenic crops have nutritionally favourable effects on insects?
An article published in Ecology Letters, March presents an idea that larvae of some resistant populations of the diamondback moth, Plutella xylostella (L.), may be able to use Cry1Ac toxin derived from Bt as a supplementary food protein. Bt transgenic crops could therefore have unanticipated nutritionally favourable effects, increasing the fitness of resistant populations. This idea is discussed in the context of the evolution of resistance to Bt transgenic crops. (2003-03-12)

Alarm pheromone causes aphids to sprout wings
When aphids are attacked by predators such as ladybird beetles, they release an alarm pheromone, (E)-รข-farnesene, that has long been known to cause other aphids to walk around or drop from the plant. In a paper soon to appear in Ecology Letters, researchers at the University and Max-Planck-Institute in Jena, Germany, now show that exposure to alarm pheromone also causes pea aphids to produce winged offspring that leave their host plant when mature. (2005-05-18)

How some insects manage to halt their own growth in harsh conditions
Most insects alter their own development or physiology to overcome adverse conditions, such as harsh winters. Although day length and temperature are known to regulate this change, exactly how this process occurs is not very clear yet. In a collaborative study, a research group from Okayama University, Tokushima University, and Pompeu Fabra University showed how a specific insect undergoes seasonal adaptation in its immature state.
