FAO Desert Locust Bulletin No. 361 - 03 Nov 2008
 
General Situation during October 2008
 
Forecast until mid-December 2008
 
The Desert Locust situation remained calm during October. As the
seasonal rains ended and vegetation dried out, locusts declined in the
summer breeding areas of the Sahel in West Africa and Sudan, and along
the Indo-Pakistan border. Small-scale breeding occurred in western
Mauritania and in southern Yemen. During the forecast period, breeding
will continue in these places, causing locust numbers to increase
slightly. Small-scale is expected to start in northern Mauritania where
scattered adults are present and in adjacent areas of Western Sahara
where unusually heavy rains fell in September. Breeding is also likely
to take place on the Red Sea coastal plains and perhaps in eastern Yemen
where torrential rains and fl ooding occurred in October. Elsewhere, low
numbers of adults will persist in northern Mali, Niger and southern
Algeria. The two areas of unusual rainfall in northwest Africa and Yemen
need to be surveyed regularly to monitor breeding activities in the
coming months.
 
Western Region. Locust numbers increased in western Mauritania from
local breeding during October and as adults arrived from summer breeding
areas where vegetation had dried out. Solitarious adults were seen in
northern areas that received heavy rains in September. Small-scale
breeding will continue during the forecast period in western Mauritania
where small groups could form, and is expected to commence in the
northwest and north. Breeding is also expected to take place in Western
Sahara where ecological conditions had improved. Isolated solitarious
adults persisted in central and northeastern Chad. Surveys were still
not possible in northeast Mali and northern Niger where scattered adults
are probably present and are likely to concentrate in areas that remain
green during the forecast period. No locusts were seen in southern
Algeria or reported from other countries in the Region.
 
Central Region. Locust numbers declined in the summer breeding areas in
the interior of Sudan during October and only scattered solitarious
adults remained in a few places between the Nile and the Red Sea Hills.
No locusts were reported in winter breeding areas on the Red Sea coast
of Egypt, Sudan and Eritrea. Low numbers of locusts were present on the
Red Sea and Gulf of Aden coast in Yemen, and smallscale breeding
occurred near Aden. Unusually heavy rains fell for two days in eastern
Yemen, causing severe fl ooding and loss of property and life. The rains
extended into central Oman. Once the waters recede, ecological
conditions are expected to remain favourable for breeding for several
months. During the forecast period, locusts will increase along both
sides of the Red Sea and small-scale breeding is likely to commence as
conditions become suitable. Most of the breeding may be concentrated on
the coastal plains in Yemen that have received rains for the past few
months.
 
Eastern Region. The locust situation remained calm in the Region. Low
numbers of solitarious adults persisted in the Cholistan Desert in
Pakistan along the Indian border. No locusts were seen in Rajasthan,
India. As the monsoon rains ended and vegetation is drying out, locust
numbers will continue to decline. Isolated adults persisted on the coast
in southeast Iran. During the forecast period, isolated adults are
likely to persist in southeast Iran and appear in western Pakistan. No
signifi cant developments are likely.
