April Flowers for redOrbit.com - Your Universe Online Researchers are puzzled by a 115-million-year-old fossilized wasp from northeast Brazil. The puzzle rests in the wasp's ovipositor, the organ through which it lays its eggs. The fossilized wasp's ovipositor looks a lot like those of present-day wasps that lay their eggs in figs. The researchers say that the problem is that figs arose around 65 million years after this wasp was alive. The wasp belongs to the Hymenoptera superfamily...

Although fairyflies are among the most common chalcid wasps, they are seldomly...

Rearing Technique Could Help Biocontrol Wasp's Commercial Prospects
2012-10-09 17:46:56

Two to three millimeters long, the parasitoid wasp Habrobracon hebetor is a top candidate for use in programs to biologically control Indianmeal moths and other stored-product pests. But despite the prospects for reduced insecticide use and product losses, the approach has yet to gain traction commercially, in part because of the lack of an efficient method of stockpiling the wasp. But a team of scientists, including researchers from the U.S. Department of Agriculture (USDA), is working on...

Figs and fig wasps have evolved to help each other out: Fig wasps lay their eggs inside the fruit where the wasp larvae can safely develop, and in return, the wasps pollinate the figs. But what happens when a wasp lays its eggs but fails to pollinate the fig? The trees get even by dropping those figs to the ground, killing the baby wasps inside, reports a Cornell University and Smithsonian Tropical Research Institute study published in the Proceedings of the Royal Society B (published online...
