The 'yellow crazy ant' lays trophic eggs to provide nutrition to their larvae.
An international team headed up by researchers from the University of Zurich has discovered the gene that determines the male sex in houseflies. Surprisingly, the sex-determining mechanisms are not the same for all houseflies -- they depend on where the insects live. This knowledge not only helps us better understand the evolution of sex determination, but also aids in the control of agricultural pests or carriers of disease.
Plants can absorb nutrients through their leaves as well as their roots. However, foliar fertilization over an extended period is difficult. In the journal Angewandte Chemie, German researchers have now introduced an efficient delivery system for micronutrients based on biohybrid microgels. Special peptides anchor the 'microcontainers' onto the leaf surface while binding sites inside ensure gradual release of the 'cargo'.
A study from Indiana University published May 19 in the journal Science Advances finds that insects possess a naturally occurring resistance to the use of gene-editing technology to prevent diseases such as malaria.
Scientists at the University of California, Riverside have developed an inexpensive, biodegradable, seaweed-based ant bait that can help homeowners and farmers control invasive Argentine ant populations.
By deploying green clay caterpillar models across six continents, researchers unmasked an important global pattern. Their discovery that predation is most intense near sea level in the tropics provides a foundation for understanding biological processes from crop protection and carbon storage to the effects of climate change on biodiversity.
Monarch butterfly populations are shrinking. New research at Michigan State University, published in the current issue of the journal Ecography, makes a strong case that the reasons for this decline go far beyond what's happening on the wintering grounds and addresses a current controversy about the primary causes of the specie's decline.
Researchers have solved a key mystery of how plants tell time, say scientists from Southern Methodist University, Dallas. Researchers learned a chemical bond in the protein Zeitlupe forms and breaks in reaction to sunlight at varying rates, signaling plants when to bloom, metabolize and store energy, and other functions. The discovery means plant clocks can be tuned by targeted mutations to plant proteins that may improve resistance to pathogens and crop yields.
To better understand the effects of climate change on agroecosystems, researchers Daugherty, Zeilinger, and Almeida conducted one of the first transdisciplinary studies on the effects of temperature change, leafhopper vector behavior, and the spread of Pierce's disease on grapevines. The results, published in Phytobiomes, show that, although a warming climate may exacerbate disease symptoms in infected grapevines, innate vector behavior may set an upper limit on the extent of Pierce's disease spread.
Possible sustainable solution to continuous cropping.
