Insect farming gains ground in fight against hunger

A kg of crickets sells for twice the price of beef in the Kinshasa market

There is no shortage of protein in Kinshasa’s Gambela Market, from cows to antelope and snakes. But it is the blue and silver bowls brimming with twitching crickets, termites and slithering mealworms that do the briskest trade. Experts hope that the love of edible insects in Democratic Republic of Congo may hold the key to

Manitoba crop insect and disease update

Conditions as of July 21, 2015

Levels of armyworms are starting to decline in some fields as they turn to pupae. Currently, scout for grasshoppers around field edges. In corn, now is the time to be scouting for European corn borer. Also consider scouting for aphids in cereals and pulse crops. Pulse Crops Soybean aphids: Soybean aphids have just started to show up in


Traps to monitor adult moths of bertha armyworm are currently only at levels suggesting low risk of damage.

Some localized higher populations of armyworms and grasshoppers are present. So scouting is encouraged, although in many cases populations are noticeable but not economical. Armyworms continue to be found in many cereal fields. In many fields they are noticeable but not economical, however some fields have had levels greater than the 4 or more larvae/ft2


flea beetles

Be on the lookout for three early-season crop pests

MAFRD entomologist John Gavloski has advice on flea beetles, 
cutworms and wireworms for Manitoba farmers

Be on the lookout for flea beetles, cutworms and wireworms, all of which can take a bite out of yields early in the growing season, says John Gavloski, entomologist with Manitoba Agriculture, Food and Rural Development (MAFRD). Canola is especially vulnerable to flea beetle damage during the cotyledon to second true-leaf stage, Gavloski said during

Soybean aphids found near Morden, but don’t panic

They've finally arrived, but the pest isn't likely to cause economic damage this season

The first soybean aphids of the season have been found near Morden but there are so few and it’s so late they are unlikely to be an economic pest this season, says Manitoba Agriculture, Food and Rural Development’s entomologist John Gavloski. “It’s happening very late so there could be some later-seeded fields that are still

The neonic debate: science or sensationalism?

Laying the blame for a collection of environmental issues at the feet of a 
single technology is very convenient, but hugely overly simplistic

Bold, apocalyptic headlines make for great front-page news stories, there’s no question. Unfortunately, when it comes to highly complex and scientific issues, these kinds of headlines usually do a disservice to the topic at hand. Scientific research is filled with intricacies and rarely yields answers that can be conveyed in a single headline. Far too

Plants can hear the difference

They respond differently to vibrations caused by 
chewing insects than to wind

University of Missouri-Columbia – Researchers at the University of Missouri-Columbia have found plants can not only tell the difference between the sound waves caused by insects chewing and wind but they respond with more defences. ‘We found that feeding vibrations signal changes in the plant cells’ metabolism, creating more defensive chemicals that can repel attacks

Insect farms: Investors see big profits in thinking small

Flies fed garbage become an environmentally friendly source of protein

When it comes to resolving a big global food problem, a new breed of farmers and their financial backers are thinking small. Work on the world’s largest fly farm has begun in South Africa after the European firm behind the project won much-needed funding from investors, propelling the use of insects as livestock feed beyond
