A new study in the Journal of Medical Entomology offers the best look yet at the Haller's organ, a small sensory pit on the forelegs of ticks that they use to detect heat and chemical odors emitted by potential hosts.
A new study in Connecticut finds that residential habitats harbor a greater diversity of animal hosts for blacklegged ticks, many of which don't transmit the Lyme disease pathogen Borrelia burgdorferi to ticks as well as white-footed mice do, thereby leading to lower levels of the pathogen's presence in residential areas compared to woodland habitats.
A study by entomologists in Italy found that the abundance of bark- and wood-boring beetles outside their native range but still within the same country is correlated with levels of trade at nearby sea ports, suggesting domestic sea transportation plays a role in insects' intra-country range expansion.
A new study shows that fertilizer present in water where mosquitoes breed can boost growth of bacteria, algae, and fungi, which mosquito larvae feed on, resulting in accelerated larval development and greater survival rates to adulthood.
In cicadas, a world of microbes has evolved to provide them nutrients. Researchers at the University of Montana have discovered that a cicada bacterial endosymbiont, Hodgkinia cicadicola, has split into at least two dozen lineages within cicada cells, in an apparent case of nonadaptive evolution.
Researchers at USDA's Agricultural Research Service identified a chemical that enhances capture of the invasive brown marmorated stink bug (Halyomorpha halys) in pheromone traps
What happens in the forest after Emerald Ash Borers kill a tree?
Queens of bumble bee Bombus impatiens that encounter imidacloprid in their spring foraging period delay nest initiation and brood emergence
Should growers that use Bt crops plant a separate nearby refuge field of non-insecticidal crops, or use a blended mixture of seeds that produce both in the same field?
Grape root borers are slow killers of grape vines, but also are hard to detect.
The Invasive Brown Marmorated Stink Bug is a major pest; USDA researchers hope to breed a resistant soybean.
How did a ground-dwelling insect like the termite Macrotermes gilvus get from mainland Myanmar all the way out to the islands of the Philippines, Indonesia, and Malaysia? The answer lies in ancient land bridges.
A naturally occurring botanical compound found in anise, fennel, vanilla, and cranberries might be effective in deterring the larval stage of the lone star tick
Most Essential oils don't work to control bed bugs, although there are a few exceptions
Light traps are useful collecting devices to sample large numbers and species of insects, but they also may mask infestations of some insect-borne illnesses and even expose humans to disease vectors.
New research identifies the genetic code by which butterflies assign color patterns to different parts of their wings
