German cockroaches

Sixty-two novel experimental carboxamides of 1,2,3,6-tetrahydropyridine have been tested as repellents of German cockroaches, and five provided 100% repeUency for 17 d in a stringent test (48). 

The optically active Trogoderma -pheromones ( )- and (Z)-24have been synthesized starting from (5)-citronellol and 4-pentynoic acid [192], Alkatrienes 25, sex attractants of Lepidoptera, were prepared by mixed Kolbe electrolysis with linolenoic acid [193], 26, the pheromone of the German cockroach Blattela Germanica has been prepared from 3-methylheneicosanoic acid [194], ( ) — Tuberculostearic acid (27) has been...

Because of the importance of safe insecticides in the protection of foods, additional tests have been run against German cockroaches, red flour beetles, and Mexican bean beetle larvae. The residual deposit test was used on the first two insects, and a dust test on the bean beetles. The procedure for the latter method is to incorporate the materials into dusts which are distributed on bean leaves (6) piperonyl cyclonene, which is superior to butoxide against this insect, was included in this series of tests.

On the other hand, the lethal efficacy for adult house flies (Musca domestica) is about the same as D-allethrin and approximately 0.5 that of prallethrin. In addition, the efficacy for female adult German cockroaches (Blattella germanica) is approximately twice that of D-allethrin and approximately 0.5 that of prallethrin. From the results mentioned above, we can see that Metofluthrin has an extremely high lethal efficacy for mosquitoes in particular.

Relatively high concentrations of boron componnds are used to control fruitflies, cockroaches, gypsy moth larvae, houseflies, and woodboring insects (Sprague 1972 USEPA 1975 Table 29.6). Boric acid is an effective stomach poison for several insect species, including German cockroaches (Blattella germanica), that are unable to detect the presence of boric acid (USEPA 1975). Insect infestation of wood and other substrates can be prevented by pretreatment with boric acid or borax at...
