Lygus bug on a canola pod

Fusarium levels low, soybean aphid numbers increasing

Manitoba crop insect and disease update for August 4, 2015

Plant Pathogens: Levels of fusarium head blight are being reported as low in many areas. Increased levels of mycosphaerella are being reported in later seeded field peas in the southwest as a result of the cooler and wetter conditions. Some soybean fields are showing increasing damage due to excess moisture and subsequent root rots. Weather conditions have been conducive for

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

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.

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 on the back of a soybean leaf. The white spots are discarded soybean aphid skins. The economic threshold for spraying to control soybean aphids is 250 aphids per plant and rising.

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

This is a cabbage butterfly caterpillar feeding on an Arabidopsis plant where, on an adjacent leaf, a piece of reflective tape helps record vibrations.

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

MAFRI pest and disease report for June 25

Manitoba Agriculture has posted its weekly insect and disease update for June 25. View the full report. Highlights • Flea beetle numbers are starting to decline, and cutworms are advancing into their final larval stages or starting to turn to pupae. • Grasshoppers hatch continues, check field edges and other suitable egg-laying areas to determine


A cake filled with edible insects in the shape of the cookbook The Insect Cookbook is displayed at the University of Wageningen. Research by scientists at the university showed that insects could provide the best source of protein to meet the needs of a rising population.

Want to lose weight? Eat bugs!

The thought of eating beetles, caterpillars and ants may give you the creeps, but the authors of a UN report published earlier this month said the health benefits of consuming nutritious insects could help fight obesity. More than 1,900 species of insects are eaten around the world, mainly in Africa and Asia, but people in

During spring and fall, mass occurrences of the Asian lady beetle can often be observed. photo: supplied

Asian lady beetles use biological weapons

Scientists have recently figured out how the Asian lady beetle has so rapidly overtaken native beetle populations in Europe and North America. Researchers from the University of Giessen and the Max Planck Institute for Chemical Ecology in Jena, Germany say the Asian beetle is capable of infecting its competitors with a deadly parasite. First introduced
