Behaviours indicating cannibalistic necrophagy in ants are modulated by the perception of pathogen infection level

 

Cannibalistic necrophagy is rarely observed in social hymenopterans, although a lack of food could easily favour such behaviour. One of the main supposed reasons for the rarity of necrophagy is that eating of nestmate corpses carries the risk of rapid spread of pathogens or parasites. Here we present an experimental laboratory study on behaviour indicating consumption of nestmate corpses in the ant Formica polyctena. We examined whether starvation and the fungal infection level of the corpses affects the occurrence of cannibalistic necrophagy. Our results showed that the ants distinguished between corpses of different types and with different levels of infection risk, adjusting their behaviour accordingly. The frequency of behaviours indicating cannibalistic necrophagy increased during starvation, although these behaviours seem to be fairly common in F. polyctena even in the presence of other food sources. The occurrence and significance of cannibalistic necrophagy deserve further research because, in addition to providing additional food, it may be part of the hygienic behaviour repertoire. The ability to detect infections and handle pathogens are important behavioural adaptations for social insects, crucial for the fitness of both individual workers and the entire colony.

Bird flu pandemic could be โ€˜100 times worseโ€™ than COVID, scientists warn

A bird flu pandemic with the potential to be โ€œ100 times worse than COVIDโ€ may be on the horizon after a rare human case was discovered in Texas, experts have warned.

 

The H5N1 avian flu has spread rapidly since a new strain was detected in 2020, affecting wild birds in every state, as well as in commercial poultry and backyard flocks.

 

But it has now even been detected in mammals, with cattle herds across four states becoming infected, and on Monday, federal health officials announced that a dairy worker in Texas caught the virus.

 

โ€œThis virus [has been] on the top of the pandemic list for many, many years and probably decades,โ€ Dr. Suresh Kuchipudi, a bird flu researcher from Pittsburgh, said at a recent panel discussing the issue, according to the Daily Mail.

 

โ€œAnd now weโ€™re getting dangerously close to this virus potentially causing a pandemic.โ€
