Pest prevention and control measures have effectively slowed the migration of yellow-spined bamboo locusts in Jiangcheng County in southwest China's Yunnan Province, officials say.

The results have been warmly welcomed.

In late June, swarms of locusts flew across China's southwest borderline. As of Tuesday, they had caused damage to more than 9,333 hectares of crop field and forest in the province.

None have been seen in Jiangcheng for four consecutive days as a result of prevention and treatment work, according to prevention and control experts, but they cautioned that the possibility of another wave of migration still exists.

"There are four large batches of yellow-spined bamboo locusts on a scale [and] judging from the current situation, we adopt the prevention and control plans that are formulated and guided by the Forestry and Grassland Bureau for each batch," said Ze Sangzi, an expert of Yunnan's guidance group of yellow-spined bamboo locust prevention and control. "The yellow-spined bamboo locusts that flew into China have been effectively eliminated. The swarms of the locusts have been effectively controlled, and the number and density have been greatly reduced."

As of Tuesday, pest prevention and control measures had been applied to more than 8,000 hectares of land in Yunnan Province.
