Eating Insects Isn’t as Eco-Friendly As People Say
Crickets are hailed as the future of food, an alternative, sustainable source of protein. But a new study questions their eco-friendliness

The last thing anybody wants is more mosquitoes. The whining little bloodsuckers can spread viruses like dengue, West Nile, yellow fever, and chikungunya. We spray mosquitoes with pesticides, drain their swampy homes, and poison their young. We slather ourselves in foul-smelling repellants, sleep beneath gauzy nets, and even prime our...

Crickets Are Not a Free Lunch: Protein Capture from Scalable Organic Side-Streams via High-Density Populations of Acheta domesticus
It has been suggested that the ecological impact of crickets as a source of dietary protein is less than conventional forms of livestock due to their comparatively efficient feed conversion and ability to consume organic side-streams. This study measured the biomass output and feed conversion ratios of house crickets ( Acheta domesticus ) reared on diets that varied in quality, ranging from grain-based to highly cellulosic diets. The measurements were made at a much greater population scale and density than any previously reported in the scientific literature. The biomass accumulation was strongly influenced by the quality of the diet (p<0.001), with the nitrogen (N) content, the ratio of N to acid detergent fiber (ADF) content, and the crude fat (CF) content ( y=N/ADF+CF ) explaining most of the variability between feed treatments (p = 0.02; R2 = 0.96). In addition, for populations of crickets that were able to survive to a harvestable size, the feed conversion ratios measured were higher (less efficient) than those reported from studies conducted at smaller scales and lower population densities. Compared to the industrial-scale production of chickens, crickets fed a poultry feed diet showed little improvement in protein conversion efficiency, a key metric in determining the ecological footprint of grain-based livestock protein. Crickets fed the solid filtrate from food waste processed at an industrial scale via enzymatic digestion were able to reach a harvestable size and achieve feed and protein efficiencies similar to that of chickens. However, crickets fed minimally-processed, municipal-scale food waste and diets composed largely of straw experienced >99% mortality without reaching a harvestable size. Therefore, the potential for A . domesticus to sustainably supplement the global protein supply, beyond what is currently produced via grain-fed chickens, will depend on capturing regionally scalable organic side-streams of relatively high-quality that are not currently being used for livestock production.

Risk, trust, and GMOs: can understanding fears help alleviate them?

Molten Aluminum Makes Casts of Ant Nest
Ants are highly social creatures who live in colonies made up of hundreds or thousands of members. Red imported fire ants (Solenopsis invicta) are a highly aggressive species that have a painful bite, and they can destroy crops and eradicate birds, lizards, and ground-dwelling bees from an area.

Western corn rootworms (CRM) resistant to Bt appear to be gaining ground. Initially, resistance concerns were limited to Cry3Bb1; however Aaron Gassman, Extension entomologist, Iowa State University, has since found resistance to mCry3A and reports problems with Cry34/35Ab1. Early reports out of central and east central Illinois suggest the problem may have taken a turn for the worse in that state, while pressure was down in Minnesota hotspots.

Should you really start eating insects?
Earlier this month, the UN released a paper touting the nutritional and environmental benefits of insects. The paper caused quite a stir in the media, with a mix of fascination, head-nodding, and not a little revulsion. But why is the UN advocating entomophagy? Why aren't we eating bugs already? And should you really dip your tongue in the waters of insect cuisine?
