Abstract
The eggs ofArgas reflexus were splashed with the LiCl and Na2Cr2O7 saturated solutions on the 2nd day after laying and were kept at 25° C and 30% RH.
Both examined chemical compounds caused great disturbances in embryogenesis ofArgas reflexus. Under influence of Na2Cr2O7 24.8% eggs died. The LiCl solution appeared to be more harmful on larvae development. 21.8% dead eggs, 11.6% dead embryos, and 8.9% larvae hatched abnormally were observed in these experiments
Zusammenfassung
Hemmende Faktoren bei der Embryonalentwicklung vonArgas (Argas) reflexus (Fab.) (Acari, Argasidae)
Die Eier vonArgas reflexus wurden am 2. Tag der Embryonalentwicklung bei 25° C und 30% r. L. der. Wirkung gesättigter Lösungen von LiCl und Na2Cr2O7 unterzogen.
Beide chemischen Verbindungen verursachten große Störungen der Embryogenesis vonArgas reflexus. Unter dem Einfluß von Na2Cr2O7 starben 24.8% der Eier ab. LiCl erwies sich als schädlicher für die Embryonalentwicklung dieser Zeckenart als Na2Cr2O7.
Bei den Experimenten mit LiCl wurden 21.8% Eier, 11.6% Embryos und 8.9% (abnormal geschlüpfte) Larven getötet.
