Six Tandem Cherries -> Very Bright Insects

Insect genetic modification technologies rely heavily on the use of fluorescent proteins as genetic markers, expression reporters etc. Colors vary, as do fluorescent outputs. Shearin et al. (2014) describe their efforts to increase signals from two popular fluorescent proteins, EGFP […]

Insect Genetic Technologies To Control Blow Flies

Blow flies (family Calliphoridae) can be serious and dangerous pests. The new world screwworm fly (Cochliomyia hominivorax) as the latin name says can be a man-eater (hominivorax). While many blow flies prefer to lay eggs on dead and decaying animals, […]

Delivering Reprogramed Meganucleases With Lentiviruses- Is this Applicable to “Difficult” Insects?

Delivering biologically relevant nucleic acids and proteins to appropriate cells of multicellular organisms for the purposes of genetically modifying either somatic or germline genomes is a central problem for not only insect biologists but for those working on other organisms […]

Genetically Modified Annelids: Platynerieis dumerilii. Not Unlike Modifying Insects

The bristle worm, Platynerieis dumerilii, is a marine annelid with a biology that makes it of interest because of the development of its nervous system, reproductive cycles that are synchronized with lunar phases and its neuroendocrinology among other things. Even […]

Densovirus Delivery of DNA to Anopheles gambiae

While the genetic technologies available for using in Anopheles mosquitoes and Anopheles gambiae in particular continue to expand, most rely on integrating transgenes into germ-lines to create genetically modified lines of mosquitoes. Of course, there is direct injection of dsRNA […]

Controlling Malaria Mosquitoes With Genetics

A chemical-free eradication method for the human malaria mosquito, Anopheles gambiae, that is self-sustaining and requires no additional inputs beyond ‘pushing the button’ to get it started, sounds fantastic. For geneticists it has not been terribly difficult to think of […]
