Rhodesia. The entomological problems of Rhodesia are 

 not very dissimilar on the whole to those of South Africa, 

 although there are certain lines of inquiry which are peculiar 

 to this region. Mr. R. W. Jack, the Government Entomologist 

 has his headquarters at Salisbury and is assisted by Mr. R. L. 

 Thompson. Their work follows along the usual lines outlined 

 in the case of South Africa. Under the "Importation of 

 Plants Regulations" and "Nurseries Ordinance" the Govern- 

 ment prevents the introduction and spread of insect pests and 

 plant diseases. Four ports of entry have been established, 

 namely, Salisbury, Bulawayo, Umtali and Gwelo, at which 

 fumigation houses are maintained. ' Nurseries must register 

 and are inspected annually. 



The country is subject to locust plagues and native com- 

 missioners, cattle inspectors and members of the British South 

 African police are required to report with full details any swarms, 

 for the control of which locust poison, spray pumps, etc., are 

 kept on hand. The Government protects the chief bird enemies 

 of the locust, such as the White Stork, Cattle Egret, Lesser 

 Locust Bird and Wattled Starling. 



Much attention has been devoted by Mr. Jack to the 

 study of Tse-tse flies and each year he devotes a portion of 

 his time to travelling through the "fly" belts for the purpose 

 of making bionomical investigations and delimiting the areas 

 of these belts. Areas infested with Glossina morsitans are 

 defined by government regulations and adjacent areas, or 

 "open areas" are also defined in which the destruction of all 

 game, with the exception of ostriches and certain game birds, is 

 permitted. The results of Mr. Jack's investigations have been 

 published in the Bulletin of Entomological Research. 



Other investigations are mainly concerned with pests of the 

 more important crops, such as corn (maize), citrus fruits and 

 tobacco and with the pests of lesser cereals, field crops, vege- 

 tables and stone fruits. The wide range of plants and trees 

 cultivated on the high and low parts of the territory offer an 

 unusual broad field for research. Tenebrionids are very 

 common and have been studied and also pests of corn (maize). 

 A formidable problem is afforded by certain fruit-piercing 

 moths belonging to the genera Maenas, Ophiusa, Achaea and 

 Sphingomorpha, which severely injure practically all fruits.
