Grasshoppers take over Sask. fields as hot, dry weather intensifies

Don Fauser says he's encountered "waves" of grasshoppers on his farm near Woodrow — about 175 kilometres southwest of Regina.

"They jump on you," Fauser said. "It's miserable."

He said the insects damaged his canola and durum crops, which were about ready for harvest. They've also eaten raspberry and peony plants on his deck and are clinging to the sides of his house.

His wife, Delores, even found one grasshopper in their bathtub. 

He's surprised by their appetite. The insects have eaten all of the leaves off of nearby trees, and even started eating the needles on evergreens.

"But they don't bite," he joked. "If we wait [until] January they won't be around."

The Fausers aren't the only ones contending with grasshoppers. Todd Lewis, who farms near Gray — about 35 kilometres south of Regina — noticed them early in the growing season.

"We did have a significant amount of grasshopper eggs," said Lewis. "You could actually see them in the fields and around the buildings."

Lewis is also a representative for the Agricultural Producers Association of Saskatchewan. He said farms in the south that have seen little moisture this summer —particularly in the southwest — have struggled the most, and likely will until their crop is harvested.

Harvest is about to start in much of the province and while some areas have been too wet, and others too dry, there's another factor making things challenging -- grasshoppers are showing up in droves.

Lewis said he's heard from producers in that area that the insects are not just in ditches around the edges of fields, but have moved inward, devouring entire crops.

Damage can range from hundreds to thousands of dollars per hectare, said Lewis.

"Perfect storm" of weather fuels grasshoppers

James Tansey, the province's entomologist, said this year has been bad for grasshoppers, particularly in southern Saskatchewan. He said last year's weather created a "perfect storm" for grasshopper growth.

"We had a nice warm spring, so that sped them through their development, so we had an early hatch" said Tansey.

"Probably most important, [Saskatchewan had] a really long, dry, protracted late summer and fall, so there was a really long period for these animals to get eggs into the ground."

The Prairie Pest Monitoring Network, which tracks insect development on the Prairies, notes that between 75 and 90 per cent of the grasshopper population in portions of the province are now in the egg stage, and those will hatch next spring.

Tansey said some grasshoppers are still nymphs — or young grasshoppers — and they will likely stay active until a hard freeze in the fall.

He warned next year's numbers could once again be significant.

"If people have grasshoppers in their region currently at significant densities, and the warm, dry weather continues, they should probably be looking forward to grasshopper populations again next year."

The monitoring network also counts grasshoppers at survey stations across the province. Last year, an average of 3,442 grasshoppers were counted per trap. The highest recent number was 3,763 per trap in 2016.

This year's numbers are yet to be determined.

Spraying crops is the most popular way farmers have tried to win the battle against the insects, but both Lewis and Fauser say nature will likely have to take its course by bringing colder weather.

"Eventually it kind of looks after itself ... I hope," said Fauser.
