New UA research has discovered that seed beetles from the desert Southwest shelter their broods from attacking parasitic wasps under a stack of dummy eggs They lead modest lives among the palo verde, mesquite and acacia trees throughout the Southwestern U.S., laying their eggs on seed pods and defending the survival of their offspring against the parasitic wasp species that attacks their eggs before their young can develop. They are the seed beetles Mimosestes amicus, living all around...

Across many groups of animals, species with bigger brains often have better cognitive abilities. But it's been unclear whether overall brain size or the size of specific brain areas is the key. New findings by neurobiologists at the University of Washington suggest that both patterns are important. The researchers found that bigger-bodied social wasps had larger brains and devoted up to three times more of their brain tissue to regions that coordinate social interactions, learning, memory and...

In Australia, when crossing from one state to another, travelers may encounter a quarantine stop and may be required to forfeit recently purchased fruits and vegetables as a hedge against invasive pests. But in the U.S., crossing state lines is free wheeling, according to researchers from the U.S., Australia and New Zealand, who evaluated the threat of invasive pests to states from within the country. "We concluded that the immediate threat from known invasive insect pests is greater from...

Social status in paper wasps is established earlier in life than scientists thought, says a study published this month in the journal PLoS ONE. While many social insects have distinct social classes that differ in appearance and are fixed from birth, paper wasp society is more fluid "” all castes look alike, and any female can climb the social ladder and become a queen. Now, molecular analysis reveals that paper wasp social hierarchy is less flexible than it appears. Queens diverge from...

Detecting exotic pests before forest and agricultural invasion In the 1930s, soil used as ballast to weigh down cargo ships from South America to Mobile, Alabama introduced the red imported fire ant to the southern United States. Since then, the ants have been found as far north as Maryland and as far west as California, shorting out streetlights and eating through crops and native plants in the process. Plant pests like the fire ant cost the U.S. an estimated $37.1 billion per year in...

A switch from annual to multiyear colonies and a willingness to feed just about any prey to their young have allowed invasive yellowjacket wasps to disrupt native populations of insects and spiders on two Hawaiian islands, a new study has found.By analyzing the DNA from bits of prey snatched from foragers returning to nests, ecologists from the University of California, San Diego, found that introduced yellowjacket wasps kill or scavenge prey from 14 different taxonomic orders of animals,...

Scientists trying to understand how the brains of animals evolve have found that evolutionary changes in brain structure reflect the types of social interactions and environmental stimuli different species face.The study is the first to compare multiple species of related animals, in this case social wasps, to look at how roles of individuals in a society might affect brain architecture. The research looks at brain structure differences between species, asking how the size of different brain...

Which came first, social dominance or big brains? Wasps may tell There's new evidence supporting the idea that bigger brains are better. A study of a tropical wasp suggests that the brainpower required to be dominant drives brain capacity. University of Washington researchers have found that key processing regions in the brains of both males and females of one wasp species not only increased in size with age but were also associated with being dominant. The study also showed different...
