The idea of genetic control of insect pests and vectors was invented independently three times in the 1930s-40s. Results with releases of radiation-sterilized male tsetse have been encouraging. Much work was done in the 1970s on mosquitoes with sterile males and systems that could potentially be used for gene driving. Chemosterilized Anopheles separated from females by a genetic sexing system w...

The objective of this study was to compare the efficacy of oxytetracycline, enrofloxacin and imidocarb for the elimination of persistent Anaplasma marginale infection in naturally infected Sahiwal cattle. A total of sixty Anaplasma marginale seropositive adult Sahiwal cattle were selected having their ages between 3-4 years ranging in weight from 246-341 kg. The animals were divided in four gro...

To evaluate the importance of the timing of an application of a chemosterilant, we measured the effect of Ornitrol on testis size and maturation of sperm cells at different time periods during testis growth and in two different breeding seasons. Indoor experiments showed that Ornitrol did not affect testes nor sperm cells when applied at the onset of testes growth. but did have an effect when a...

This study describes the induction of chemosterilization in three groups each of six adult male Black Bengal goats at 30 days after a single bilateral intratesticular injection of a calcium chloride (CaCl(2), 2H(2)O) solution at the doses of 10, 20 or 40 mg/kg body weight/testis, always in a 2 ml volume of normal saline. Another one group of animals received only 2 ml of normal saline per testi...

The design and synthesis o f a series o f alkyl 5(6)-substituted benzimidazole-2-carbamates (1-13), 7-chloro-4-(4-substituted phenyl)aminoquinolines (14-16), l,2-dimethyl-3-methoxycarbonyl-4,5-disubstituted pyrroles (17—19) and some compounds belonging to the class pimelonitrile (20), dihydroquinoline (21), pyridine (22), pyridoquinoline (23) and tetrahydropyrimidine (24) have been carried out ...

The formamidines, a relatively new group of acaricide-insecticides, are novel both in their range of biological activities and in their mode of action, which is presently unknown. This paper is a review of the historical development, properties, structures, uses, and chemistry of this group of pesticides, with particular emphasis on chlordimeform (Galecron or Fundal), N'-4-chloro-o-tolyl-N,N-di...

The design and synthesis of a series of alkyl 5(6)-substituted benzimidazole-2-carbamates (1-13), 7-chloro-4-(4-substituted phenyl)aminoquinolines (14-16), 1,2-dimethyl-3-methoxy-carbonyl-4,5-disubstituted pyrroles (17-19) and some compounds belonging to the class pimelonitrile (20), dihydroquinoline (21), pyridine (22), pyridoquinoline (23) and tetrahydro-pyrimidine (24) have been carried out ...
