FAO DESERT LOCUST BULLETIN NO. 281
GENERAL SITUATION DURING FEBRUARY 2002
FORECAST UNTIL MID-APRIL 2002


1. SUMMARY

The Desert Locust situation remained calm during February. Only low and insignificant numbers of solitarious adults were present in parts of northwestern Mauritania and Niger, on the Red Sea coast of Sudan and Eritrea, and in western Pakistan. Although very little rain fell, breeding conditions continue to be favourable in southwestern Mauritania and perhaps in a few places on the Red Sea coast near the Yemen/Saudi Arabia border. Conditions are improving in western Pakistan. No significant developments are likely during the forecast period.

Western Region. Isolated mature adults persisted in a few places in northwestern Mauritania and northern Mali, and localized breeding occurred in Niger. No significant rainfall was reported during February but conditions are likely to be favourable for locust survival and breeding in southwestern Mauritania due to the unusually heavy rains in January. It is suggested that surveys are undertaken in these areas to clarify the situation.

Central Region. Dry conditions prevailed along the western side of the Red Sea where only a few scattered adults were seen in cropping areas in the Tokar Delta, Sudan during February. Small-scale breeding occurred on the northern coast of Eritrea where scattered late instar hoppers were reported. As a result of several successive months of rainfall, conditions were more favourable along the southern coast of Saudi Arabia and the central coast of Yemen where low numbers of locusts could be present. Surveys are suggested in these areas to clarify the situation. No locusts were reported elsewhere in the region.

Eastern Region. Isolated adults were present near the coast in western Pakistan where light rains fell in February and small-scale breeding could occur during the forecast period. This area should be checked during the joint survey between I.R. Iran and Pakistan in April. No locusts were reported in the region and no significant developments are expected.

 

2. WEATHER & ECOLOGICAL CONDITIONS IN FEBRUARY 2002

Although very little rain fell in the recession area during February, breeding conditions remained favourable in southwestern Mauritania and along parts of the eastern Red Sea coast. Conditions are improving near the coast in western Pakistan.

In West Africa, no significant rainfall was reported or is thought to have occurred during February. In Mauritania, widespread clouds were present over the north and northwest on the 11th and light rain fell on the northern coast at Nouadhibou. Conditions were favourable for breeding in parts of southern and southeastern Tiris Zemmour. As a result of the unusually heavy rainfall in January, green vegetation was present in Trarza as far north as 1745N, in a large area of Agane (1800N/1330E), in low-lying areas of Brakna near Magta Lahjar and near Moudjeria in western Tagant. Vegetation was becoming green in some places of northwestern Inchiri and southwestern Adrar. Green vegetation persisted in a few wadis in the Adrar des Iforas, Mali and in Tamesna and western Air, Niger.

In North-West Africa, dry conditions prevailed in most of the Desert Locust areas. Light rains fell along the western coast of Morocco near Tan-Tan and Sidi Ifni at mid month. Light to moderate rains associated with a Mediterranean depression fell over a large portion of southern Tunisia and northwestern Libya on 6-9 February although no locusts are likely to be present to take advantage of these rains.

In Eastern Africa, no significant rainfall was reported and mostly dry conditions prevailed during February. In Sudan, vegetation was reported to be dry in most places along the Red Sea coastal plains from Port Sudan to the Tokar Delta because of a lack of rainfall. Green vegetation was present in the Tokar Delta where crop harvesting was in progress. Some rain may have fallen on the southern Red Sea coastal plains of Eritrea near Assaba and on the northern plains of Djibouti. Although light rain fell in eastern Ethiopia near Jijiga during the first week of February, vegetation was reported to be generally dry. In Somalia, dry conditions were reported except in the coastal areas of Bulhar and Geerisa where light showers fell and green vegetation was present.

In the Near East, rains fell sporadically in a few countries. In Egypt, clouds were present during most of the first three weeks of the month over the Western Desert due to several eastward moving Mediterranean depressions; Bahariya Oasis received 4 mm on 10-11 February. In Saudi Arabia, light to moderate rains, associated with a northerly surge of the Red Sea Convergence Zone, fell on the central Red Sea coast between Jeddah (10 mm) and Medinah (29 mm) on the 2nd. Light rains fell on the edge of the Empty Quarter where Sharurah reported 14 mm on the 18th. Light rain fell over the Musandam Peninsula, Oman and Ras Al Khaimah, UAE on the 19-20th. Despite this rainfall, dry conditions prevailed throughout most of the region except on the Red Sea coastal plains from Jizan, Saudi Arabia to Hodeidah, Yemen where green vegetation is likely to be present due to several successive months of rainfall.

In South-West Asia, conditions were slowly improving in the coastal areas of western Pakistan where light rain was reported during the second half of February At Turbat, Pasni and Gwadar. Dry conditions prevailed elsewhere in the region.

No control operations were reported during February.

 

4. DESERT LOCUST SITUATION AND FORECAST

WEST AFRICA

Mauritania

- Situation

During the first two dekads of February, isolated mature adults were seen at four locations in the northwest between Oujeft (2003N/1301W) and Zouerate (2244N1221W).

- Forecast

Low numbers of adults are expected to persist in parts of Inchiri, southern Adrar and southwestern Tiris Zemmour where there is a low possibility of small-scale breeding in areas of recent rainfall. Locusts are likely to be present in the southwest between R'Kiz and Tidjikja where unusually heavy rains fell in January. Locust numbers will increase in these areas if breeding occurs. It is recommended to undertake surveys in the southwest during the forecast period.

Mali

- Situation

During February, a few individual maturing adult locusts were seen at Aguelhok (1927N/0052E) on the 12th.

- Forecast

Isolated locusts may persist in parts of Timetrine and the Adrar des Iforas where vegetation remains green. No significant developments are likely.

Niger

- Situation

Scattered immature and mature adults at densities of 20-50 locusts per ha and a single fourth instar hopper were seen in crops near Arlit (1843N/0721E) on 24 February. No other locusts were seen during surveys carried out in February near Agadez and west of In Abangharit (1754N/0559E).
