MODERN MOSQUITO CONTROL 



Color Sound Modern Talking Picture Service 



30 minutes Free 



This film deals with the life cycle of the mosquito and raises 

 the problem of its control. Chief emphasis is placed on the elimina- 

 tion and treatment of the breeding area by sanitary landfill, effi- 

 cient drainage, alteration of the physical character of the affected 

 land by means of impoundment (flooding low-lying areas to prevent 

 the laying of eggs in moist soil). The story also details clean-up 

 methods for water containers near homes by use of oil which shuts 

 out air or helps spread insecticides. The insecticide used is 

 Melathion, developed and made increasingly powerful over the 

 years in order to cope with the diseases engendered by the mos- 

 quito. The film repeatedly emphasizes the fact that this potent 

 pesticide need not harm people, pets or food products. It is a graphic, 

 well-organized, and provocative argument that deserves attention 

 of all students interested in the research being accomplished today 

 to conquer the pests of the rival insect world.

NATURAL ENEMIES OF INSECT PESTS 



Color Sound University of California 



27 minutes Rental Sale 



Well documented with scientific observations, and occasionally 

 repetitive, this film makes an immediate impression as being pro- 

 duced by people who know what they are about and have the 

 ability to present a problem with some detachment. Particularly, 

 it discusses the efforts of citrus fruit growers to control insect pests 

 by exploiting and making use of the natural enemies of these harm- 

 ful insects. The depredations of mealy bugs, squash bugs, army 

 worms, scales, mites, aphids and others are delineated in striking 

 microscopic shots. Aligned on the opposite side are the lady beetles, 

 green lacewings, certain wasps and flies devouring the pests. These 

 insect battle fields introduce natural allies in the fight for pest 

 control. The story goes on to warn against conditions which may 

 tend to upset a natural balance by introducing the effects of chemi- 

 cal pesticides on beneficial species. 



The film also goes into the laboratory for visualizations of testing 

 effects of sprays as well as into an insectory, or nursery for raising 

 beneficial insects. All in all a valuable study in that it raises prob- 

 lems and describes effects created by widespread spraying of chemi- 

 cal pesticides. School and college biology classes will find it adds 

 dimension to entomological studies.
