Locust infestation rate extremely low this year: survey – Pakistan

ISLAMABAD: A two-year joint survey conducted at spring locust breeding sites in Pakistan and Iran found that the average locust infection rate in this year’s survey was 1.4pc, very low compared to 60pc. The last joint survey of 2019.

In Pakistan, the percentage in 2022 was only 1.4%, compared to 34% in 2019, according to the Food and Agriculture Organization of the United Nations (FAO) Joint Survey of Desert Locusts released on Wednesday.

As a result of the joint investigation, it was found that this year’s spring breeding was extremely limited due to the unusually insufficient rainfall and poor ecological environment.

As a result, there is no threat to summer breeding grounds along the Indo-Pakistan border this year, and the situation will remain calm throughout the region for the rest of the year.

The Pakistan Locust Investigation Team surveyed a total of 291 stopovers spanning 7,665 km in Baluchistan and found an estimated area of ​​59,320 ha, and in Iran, 192 stopovers spanning 9,328 km and confirmed an estimated area of ​​10,320 ha. .

Accordingly, a total of 483 stops were investigated over 16,993 km above the ground, and the total area on both sides of the border is estimated to be 70,200 ha.

The FAO report found that ecological conditions were unsuitable for locust activity in both countries. Only a few solitary adults and a few solitary hoppers have been observed in five sites along the coast of southeastern Iran and four in southwestern Pakistan. Because the conditions were dry, this year’s survey was able to achieve more distances and more stops than previous joint surveys, the report says.

In Pakistan, vegetation and soil moisture were found to be dry at all survey points. Low-density immature and mature solitary adults were observed in four regions of the Jiwani and Kolanch Valley regions.

A low density of solitary and transient hoppers was observed in one area. Low-density solitary hoppers and chicks were also observed in the Kocho region (Kolanch Valley).

The fact that there were a few late carp hoppers in Jiwani and the Kolanch Valley suggests that there was some rainfall in January or early February for laying eggs from the last week of February to mid-March.

As a result of laying these eggs, hatching probably started in the second week of March and continued until the end of the month.
