Anastrepha ludens

Studies on Helietta parvifolia. In the northern arid region of Mexico, Rovalo e al. (23) carried out a study of the potential uses of Helietta parvifolia. They demonstrated that the essential oil of Helietta acts as a fungicide upon Penicillium, Rhlzopus, Fusarlum, and Aspergillus and also acts as an insecticide upon Anastrepha ludens (fruit fly). The allelopathic potential of Helietta leaves was demonstrated upon a common weed Convolvulus arvense.

Only estimates of the numbers of compounds tested as chemosterilants can be offered. Since 1955, when insect sterility acquired a certain economic potential, close to 10,000 compounds have been screened in various USDA laboratories, primarily in house flies, screwworms, Mexican fruit flies Anastrepha ludens Loew), and boll weevils Anthonomus grandis Bohe-man). Some 600 of these compounds had more or less pronounced streiliz-ing effects, and many were further tested in over 100 species of insects and other organisms. Possibly thousands of additional compounds were screened in other laboratories here and abroad, but an exact count of the active and inactive compounds has not been made. By the end of 1972, more than 1000 insect chemosterilants were described in the scientific literature. This number is more than twice that listed in a survey published by Borkovec (1966).
