Besieged By Locusts, Farmers Fight Back

The Department of Agriculture, Forestry and Fisheries announced earlier this month that the Free State, Northern Cape and Western Cape are currently experiencing outbreaks of locusts.

In October, the swarms of locusts descended upon vast areas of land in the Karoo in the Eastern Cape, devouring the grass and destroying crops on an already drought-stricken part of the country.

In February this year, East Africa experienced the outbreak.

Professor Frances Duncan from Wits School of Animal Plant and Environmental Sciences says a locust outbreak occurs when it starts raining after a prolonged drought.

Speaking on SAfm, Duncan says locust eggs which can stay underground for up to four years, start hatching after rainfall.

She says a locust outbreak can be prevented through ploughing and monitoring, however, it would be difficult to find the egg beds.

“There have been talks about ploughing of the land, if you plough it, you will get rid of the egg beds but that could upset that land. Our locusts are in the Karoo area, where there is very little ground cover. If you ripped up all that land and if you ripped up that land, you would get rid of the feed for the sheath, so it’s very difficult to know what to do, you couldn’t burn it because that wouldn’t help, ploughing could help but we don’t know where the egg beds are, so the best is to look into monitoring.”
