Surveys were limited by insecurity and control operations were not possible because of beekeepers.

H A D H R A M A U T Hodeidah Ataq Aug- 0 swarms bands winter breeding area GULF OF ADEN AUG-SEP 0 Locust numbers increased in the summer breeding areas of the interior as a result of an earlier invasion from Saudi Arabia and subsequent breeding that caused hopper bands and swarms to form in tember. Survey and control operations were limited due to insecurity and beekeeping, and only 5,000 ha could be treated. Large areas could not be accessed where band and swarm formation were thought to be in progress. Some moved to the winter breeding areas along the Red Sea and Gulf of coasts where egg-laying and hatching caused small hopper and bands to form that were treated (0 ha) in early October.
Midi Suq Abs Al Zuhrah Hodeidah RED SEA Bayt Al Faqih Oct-Nov 0 swarms bands ERITREA GULF OF ADEN OCT-NOV 0 Adults from summer breeding areas in the interior laid eggs on the northern coast of the Red Sea that hatched in tember and October. Hoppers formed and bands throughout October and November. Fledging occurred from early October to mid-november. An immature swarm was reported on November. The new matured and started to lay eggs in mid-november. Ground teams treated nearly,000 ha on the northern Red Sea coastal plains.
Midi Suq Abs Al Zuhrah Hodeidah RED SEA Bayt Al Faqih Dec 0 swarms bands ERITREA GULF OF ADEN DEC0 Hundreds of late instar bands were present on the northern coastal plains during the first half of December. Thereafter, they decreased as fledged and the new immature formed and at least a dozen small swarms that matured throughout the month. Some of the swarms moved north into Saudi Arabia while others remained on the coast and laid eggs. Nearly 5,000 ha were treated. On the southern coast, a few hopper and bands formed northwest of, and an immature swarms was reported nearby.
Midi Suq Abs Al Zuhrah Hodeidah RED SEA Bayt Al Faqih Jan-Feb 0 bands ERITREA GULF OF ADEN JAN-FEB 0 A limited second generation of breeding occurred with hatching and band formation during January on the northern coast. Late instar hopper bands declined in February as they fledged and an increasing number of immature adult formed. An immature swarm was reported on the 7th at Al Luhyia port that may have come from local breeding or emigrated the Eritrean coast near Tio. As good rains fell at mid-month, the were maturing and laying eggs. Control teams treated 700 ha in January.

LAYING HATCHING FLEDGING! - Red Sea Mature were first reported on the northern coast near Midi on 0 tember but were probably already present, but not detected, in August. Egg-laying probably occurred throughout tember with subsequent hatching until nearly mid-october, causing hopper and bands to form until mid-december. Limited fledging started in early October and peaked in late November and early December, causing an increasing number of adult and swarms to form. Mature seen on the coast in early October and laying swarms seen on October probably originated from the last remaining infestations in the interior summer breeding areas. Second generation breeding started in December, followed by limited hatching and band formation in January, and and a few swarms from mid-february onwards.

The probably laid eggs during the first two weeks of October with hatching during the second half of the month and early November, causing locust numbers to increase and to form and small bands by mid-november. Fledging should start by the end of November and continue to about mid-december. Control operations were expected to start by the end of November once beekeepers moved their hives.
