FAO DESERT LOCUST BULLETIN No. 292
General Situation during January 2003
Forecast until mid-February 2003

The Desert Locust situation remained calm during January. Although conditions continued to be favourable in the winter breeding areas, no locusts have been reported in these places. Only isolated adults were present in Niger, southern Algeria and northern Somalia. There was an unconfirmed report of adults and hoppers in northern Mali. During the forecast period, small-scale breeding could occur along the Red Sea coasts. No significant developments are expected.

Western Region. Low numbers of adults persisted in southern Algeria and in Niger during January where they will slowly mature in the few areas that remain green. There is a slight possibility that adults may move into southern Algeria during periods of warm southerly winds from northern Mali where there were unconfirmed reports from nomads and travelers of locust adults and hoppers. No locusts were reported elsewhere in the region and the situation is expected to remain calm during the forecast period.

Central Region. Conditions continued to remain favourable for breeding in many places along both sides of the Red Sea during January but no locusts were reported. Nevertheless, small-scale breeding could occur during the forecast period on the coasts of Yemen, Saudi Arabia, Sudan and Eritrea. Isolated adults were reported in northwestern Somalia where they will mature and breed if conditions remain favourable. No significant developments are expected.

Eastern Region. No locusts were reported in the region. Conditions are improving in the spring breeding areas of western Pakistan and eastern I.R. Iran where light rains fell during January. Low numbers of adults are expected to appear in the spring breeding areas during the forecast period. No significant developments are expected.

 

Weather and Ecological Conditions in January 2003

Although only a few isolated showers fell in the winter breeding areas along the Red Sea coastal plains, conditions continued to be favourable for breeding in many places. Very little rain fell elsewhere and conditions were generally dry except for parts of northwestern Mauritania, northern Mali, Niger and southern Algeria where localized patches of vegetation were present to allow low numbers of locusts to survive.

In the Western Region, very little rain was reported or is thought to have occurred in the locust breeding areas during January. Light rain associated with eastward Mediterranean depressions fell at times during the first half of the month along the Atlantic coast in Morocco near Sidi Ifni and Tan-Tan, and north of the Sahara in Algeria near Ghardaia and Ouargla. Rain was heaviest in southern Tunisia. A few light showers may have fallen in northern Mauritania and southwestern Morocco where scattered clouds were present during the first, third and fourth weeks of January. Clouds were present for several days and isolated showers were reported in southeastern Mauritania (Nema), northern Mali (Aguelhoc and Tessalit) and in eastern Niger (Bilma). Despite the poor rainfall, conditions remained favourable on a localized scale for locust survival near Tamanrasset, Algeria, in parts of northern Mali and in a few wadis in the northern and central Air Mountains, Niger. Vegetation was reported to be nearly dry in Tamesna, Niger.

In the Central Region, isolated showers fell in a few places along both sides of the Red Sea. In Eritrea, light rain was reported on the northern coast. Light to moderate rains fell during the first and third weeks of January on the northern Red Sea coast in Yemen and moderate rains fell in early January in adjacent areas of Saudi Arabia in Jizan. Consequently, breeding conditions are favourable in most of these areas as well as on the Red Sea coast of Sudan from Tokar to just south of Mohamed Qol. Unfavourable conditions persisted on the coast further north to Shalatein, Egypt. Clouds were present over the Western Desert in Egypt on several days throughout January. On one occasion, these clouds extended to Jebel Uweinat and the Chad/Libya/Sudan border. This is one of the driest regions of the Sahara. Clouds were also seen on the Red Sea coast near the Sudan/Egypt border and along the Yemen/Saudi Arabia border in the Empty Quarter north of Wadi Hadhramaut. There is a low possibility that light showers may have occurred in some of these places. Light rainfall was reported in Djibouti Town and in northern Oman and. In northern Somalia, conditions were favourable for breeding on the escarpment and coastal plains west of Berbera where moderate rains fell during the first week of January.

In the Eastern Region, isolated showers fell in a few places along the coast in the spring breeding areas of I.R. Iran and Pakistan where vegetation is becoming green. The showers were reported at Jask, I.R. Iran and at Jiwani and Pasni, Pakistan. Light rain also fell in Rajasthan, India at Bikaner and Jaisalmer where temperatures were unusually cold and conditions were generally dry and unfavourable for locusts.

 

Area Treated

Desert Locust Situation and Forecast

( see also the summary on page 1 )

WESTERN REGION

Mauritania

- Situation

No surveys were carried out and no locusts were reported during January.

- Forecast

Isolated adults may be present in the northwest in Inchiri and perhaps further north in a few places in Adrar and Tiris-Zemmour. No significant developments are likely.

Mali

- Situation

There were unconfirmed reports of adult and hopper concentrations at a few places west of Tessalit (2011N0102E) in the Tilemsi Valley and Timetrine during the first three weeks of January.

- Forecast

As vegetation continues to dry out in the Timetrine, Tilemsi Valley and the Adrar des Iforas, locusts are likely to become concentrated and may form a few small groups. During periods of warm southerly winds, there is a low possibility that some adults could move north into southern Algeria.

Niger

- Situation

On 13-24 December, scattered first to fifth instar hoppers and immature adults were seen on the Talak Plains (1826N/0746E) north of Agadez and in a few wadis in the northern Air Mountains. In two of these places, drying vegetation forced the locusts to concentrate and increase in density, reaching up to 7 hoppers per 10 sq. metres and 4,000 adults per ha.

During the first three weeks of January, scattered immature adults declined on the Talak Plains but persisted at four locations in the central Air Mountains.

- Forecast

Locust numbers will continue to decline in Tamesna and Air as vegetation dries out and breeding conditions become unfavourable. Nevertheless, isolated adults may persist in a few places near Talak. No significant developments are likely.

Chad

- Situation

No reports received.

- Forecast

No significant developments are likely.

Senegal

- Situation

No locusts were reported during December.

- Forecast

No significant developments are likely.

Algeria

- Situation

A few individual immature adults were reported to be persisting in a few wadis near Tamanrasset during January.

- Forecast

Isolated adults will persist and slowly mature near Tamanrasset where small-scale breeding could occur if rains fall during the forecast period. These may be augmented by any adults arriving from northern Mali during periods of warm southerly winds.

Morocco

- Situation

No locusts were reported during January.

- Forecast

No significant developments are likely.

Libyan Arab Jamahiriya

- Situation

No reports received.

- Forecast

No significant developments are likely.

Tunisia

- Situation

No locusts were reported during January.

- Forecast

No significant developments are likely.

Burkina Faso, Cape Verde, Gambia, Guinea Bissau and Guinea Conakry

- Forecast

CENTRAL REGION

Sudan

- Situation

No locusts were seen during surveys carried out on the Red Sea coastal plains between Tokar (1827N3741E) and Bir Salalah (2034N/3701E) in the first three weeks of January.

- Forecast

Isolated adults are likely to be present on the Red Sea coastal plains where small-scale breeding could occur in areas that continue to remain green during the forecast period. Other locusts may be present and breeding in the northern subcoastal areas in Wadi Oko/Diib. Regular monitoring should continue in all of these areas.

Eritrea

- Situation

No locusts were seen during surveys carried out on 17-18 January on the Red Sea coast between Massawa (1537N/3928E) and the Sudanese border at Karora (1745N/3820E).

- Forecast

Isolated adults may be present in some areas along the Red Sea coastal plains between Massawa and Karora. Small-scale breeding could occur in areas of recent rainfall but no significant developments are expected.

Somalia

- Situation

Isolated immature adults were seen at two locations on the coastal plains west of Berbera (1028N/4502E) at the base of the escarpment on 7 January. No other locusts were seen in nearby areas during surveys carried out on 6-9 January.

- Forecast

Low numbers of adults will mature and breed on a small scale on the northwest coastal plains. Consequently, locust numbers will increase slightly but remain well below threatening levels.

Ethiopia

- Situation

No reports received.

- Forecast

No significant developments are likely.

Djibouti

- Situation

No surveys were carried out and no locusts were reported during December.

- Forecast
