Ant allergy is a rare problem and most published reports are from outside India. We report a toddler who suffered from severe anaphylaxis reaction due to bite of Red fire ant (Solenopsis geminata).

The red imported fire ants (RIFAs) are a globally important invasive pest that severely affects the ecosystem and human health, and its current control is primarily through chemical pesticides. However, the extensive use of chemical pesticides causes environmental problems, and alternative strategies for controlling this pest are being explored. In our study, we aimed to design a deep eutectic solvent (DES)-CaCO system in which RIFAs were used as target insects to increase the lethal activity and behavioural regulation effects on RIFAs via contact and feeding.

Along their lengths, stems experience different functional demands. Because bark and wood traits are usually studied at single points on stems, it remains unclear how carbon allocation changes along tip-to-base trajectories across species. We examined bark vs wood allocation by measuring cross-sectional areas of outer and inner bark (OB and IB), IB regions (secondary phloem, cortex, and phelloderm), and wood from stem tips to bases of 35 woody angiosperm species of diverse phylogenetic lineages, climates, fire regimes, and bark morphologies.

The house cricket, (Linnaeus), is often used as a food source for the maintenance of imported fire ants under laboratory rearing. It was found that both red imported fire ants, Buren, and black imported fire ants, Forel, consumed most of the soft tissues of female crickets, but avoided their eggs by disposing of them on refuse piles. Bioassays using freshly collected cricket eggs showed that ants first retrieved eggs into their nests and then discarded them onto the refuse piles.

Understanding the process of genetic adaptation in response to human-mediated ecological change will help elucidate the eco-evolutionary impacts of human activity. In the 1930s red imported fire ants (Solenopsis invicta) were accidently introduced to the Southeastern USA, where today they are both venomous predators and toxic prey to native eastern fence lizards (Sceloporus undulatus). Here, we investigate potential lizard adaptation to invasive fire ants by generating whole-genome sequences from 420 lizards across three populations: one with long exposure to fire ants, and two unexposed populations.
