HEMOLYMPH PH AS A MARKER OF PESTICIDE EXPOSITION
Journal Title: Folia Pomeranae Universitatis Technologiae Stetinensis Agricultura Alimentaria Piscaria et Zootechnica - Year 2017, Vol 44, Issue 338
Abstract
Changes in blood biochemical parameters reflects disorders in the whole body after exposition to contaminants. Insect hemolymph circulates in direct contact with the animals’s tissues, therefore every disruption that appears in the body is reflected in change of hemolymph parameters. The aim of this study was to assess the potential of hemolymph pH as the marker of insecticide intoxication. Experiments were performed on mealworms Tenebrio molitor L., intoxicated with insecticides’ characterized by different mechanisms of insecticidal action – pyrethroid, oxadiazine, neonicotinoid and organophospate in different ambient temperatures (15°C, 25°C and 35°C). Hemolymph pH and insects’ mortality after intoxication was assessed after three days from insecticides application. The results obtained showed a correlation between mortality and pH of the hemolymph. Intoxication with insecticides resulted in pH decrease: the greater decline was determined, the higher mortality was observed. The results indicate that hemolymph pH may be used as a marker of organism exposition to xenobiotics.
