In 1915 Anatolia, Syria and Palestine sufiered greatly from invasions 

 of the locusts, Schistocerca peregrina, Calliptamus {Caloptenus) italicus 

 and Dociostaurus {Stauronotus) maroccanus. The first-named comes 

 from Africa, survives for one or two generations and then dies out 

 owing to the unfavourable climate. This also applies to C. italicus, 

 but D. maroccanus is indigenous in the mountain districts, whence 

 enormous swarms, sometimes measuring 15 miles in length by over 

 600 yards in breadth, invade the plains. The eggs are laid from 

 July to August and hatching begins in mid-February. 



The anti-locust campaign organised by the author was conducted by 

 a stafi of 14 directors, 72 ofiicers, 2,000 supervisors, about 11,000 men 

 from the labour battalions and compulsory levies from the population.
