. Agri-news. Agriculture. FOR IMMEDIATE RELEASE ALBERTA'S 1977 GRASSHOPPER FORECAST Although the 1977 Alberta grasshopper forecast predicts a smaller grasshopper population than last year, the infestation area is still large enough to cause concern. Based on estimates of the number of grasshoppers present in the late summer and early fall of 1976, the fore- cast shows about million acres will be severely infested this year. Another million acres will be moderately infested and million acres are expected to be lightly infested. The heaviest infestations are predicted to occur north
. Agri-news. Agriculture. FOR IMMEDIATE RELEASE ALBERTA'S 1977 GRASSHOPPER FORECAST Although the 1977 Alberta grasshopper forecast predicts a smaller grasshopper population than last year, the infestation area is still large enough to cause concern. Based on estimates of the number of grasshoppers present in the late summer and early fall of 1976, the fore- cast shows about million acres will be severely infested this year. Another million acres will be moderately infested and million acres are expected to be lightly infested. The heaviest infestations are predicted to occur north-east of Leth- bridge and in the Acadia Valley area. The grasshoppers will begin to hatch in early May, and the amount of damage they do will depend upon the weather. If the spring and early summer are hot and dry, the grasshoppers could cause serious damage unless controlled. On the other hand, if the weather is cool and wet, as it was last year, hatching will be delayed and damage to crops will probably be limited. According to Dr. Holmes of the federal research station at Lethbridge, who compiles the grasshopper forecast each year, there was a high mortality rate in last year's grasshopper population. It was apparently caused by disease and continued the decline that began in 1974. /dlbara e (403) 427-2127 COMMUNICATIONS.
