Toxicological deterioration of some plant extracts on Fannia canicularis [diptera: muscidae]

The early third in star larvae of Fannia canicularis were treated with various concentrations of Rumex dentatus, Protulaca deracea and Piper cubebae extracts. The Rimes dentatus was more toxic than Protulaca deracea and Piper cubebae. The extract mixture of Rumex dentatus and Piper induced a high synergistic action against the treated larvae, but the mixture of Protulaca deracea and Piper cubebae indicated an antagonistic effect. The reproductive potential of treated insects together with the biochemistry of their ovaries and testes were determined. The results indicated that the tested mixtures had delayed effects represented by the decrease of the ovarian and testicular protein and the disturbance of their amino acid contents. This might be due in part to the interference of these mixtures with gonadal development, which affected negatively the fecundity and fertility of adults

Toxicological efficacy of some indigenous dill compounds against the flesh fly, parasarcophaga dux thomson

In this study, the effect of the LC50 of the three isolated compounds [apiol, myristicin and d-carvone] from dill, Anethum graveolens, on the growth and reproduction of Parasarcophaga dux showed that the three compounds, especially apiol, caused a significant reduction in the percentage of adults emergence and females fecundity. The temperature toxicity relation shape of the three compounds and five insect growth regulations [methoprene, hydroprene, teflubenzuron, chlorfluazuron and precocene I] alone or in combination against P. dux was studied and discussed

Enzyme activity in the flesh fly parasarcophaga dux thomson influenced by dill compounds, myristicin and apiol

In this study, the newly emerged adults of Parasarcophaga dux were treated topically with various doses of myristicin and apiol isolated from roots of dill plant, Anethum graveolens. The compounds toxicity and the dehydrogenase activities of the treated stage and its subsequent developmental stages were studied. The results indicated that apiol is more toxic than myristicin. The spectrophotometric evaluation exhibited changes in the dehydrogenase activities after treatments. Compounds increased the activities of both alpha- glycerophosphate [GPDH] and malate dehydrogenase [MDH] in first half of metamorphosis [immature stages]. But, the level of malic enzyme [ME] activities of the various stages was obviously decreased
