maculipennis (small cabbage moth), Colias electra (lucerne caterpillar) 

 and Argywploce {Enarmonia) batracJiopa (false cudling moth). It is 

 hoped to make similar studies during the following year on Phryneta 

 spinator (fig borer) and Bagrada hilaris (bagrada bug). As the effective 

 disposal of maize stumps before spring is necessary as a remedial 

 measure for the maize stalk borer [Busseola fusca], much time has been 

 spent in devising and developing mechanical appliances for uprooting 

 and raking up maize stumps, and a comprehensive report on this pest 

 will shortly be published. Combined field and systematic study of 

 the Bruchid enemies of peas and beans has been continued, and 

 parasitised material of Saissetia {Lecanium) oleae (black scale) has 

 been collected and despatched to the Horticultural Commissioner of 

 CaUfornia, this work being now suspended owing to the irregular 

 sailings due to the War. 



In Natal, special studies on insects injurious to the wattle were 

 conducted. The wattle bagworm \Cha\ioides junodi] was not so 

 abundant as in the previous year, and contemplated experiments 

 with poison-dust, applied with a motor-driven blower, could not be 

 completed, though results to date justif)^ the adoption of dusting as 

 a cheap and efi!ective means of controlling this insect in plantations.

The amazingly rapid development of the agricultural resources of 

 the United States, and the knowledge of the role which insects play 

 in the transmission of disease, have created a demand for trained 

 entomologists to cope with the many diverse insect problems concerned. 

 To meet this demand the universities and colleges have instituted 

 special courses of instruction, so that America may now justly claim 

 to be the home of applied entomology. 



This paper aims at giving some idea of the courses arranged and 

 where they may be best obtained, together ^\ath particulars of some 

 of the extensive opportunities offered.

Phthorimaea op)ercidella, Zell. (potato tuber moth) is the worst 

 pest of potatoes in South Africa. The present pamphlet is published 

 in answer to numerous inquiries regarding this insect, and is the result 

 of three seasons' observations. Tobacco is also attacked, but the 

 damage is less severe. The hfe-history and descriptions of the 

 various stages are given, and the methods of infestation are discussed. 

 Moths may r^ach the tubers through cracks in the soil, and also attack 

 those that are only partly covered. The greatest infestation probably 

 occurs through the larvae leaving the tops when the latter begin to 

 wilt, or when cold weather occurs, and boring down into the soil and 

 attacking the tubers. In some locahties as many as 50 per cent, of 

 the larvae in the leaves were found to be parasitised by an Ichneumonid^
