The Activity of Juniperus Procera Stem Extracts as Pesticides Against the Blowfly Chrysomya Albiceps (Diptera: Calliphoridae)

“…However, the present study showed that the highest mortalities were recorded in the petroleum ether extract of J. procera stem with LC 50 0.15 g/mL. The petroleum ether leaves extract of Artemisia absinthium at 0.4 g/mL caused 100% larval mortality on C. albiceps with LC 50 of 0.11 g/mL [21] . Therefore, the test methods, differences between species, and exposure time to the test materials may be responsible for the differences among the obtained results.…”

“…The reproductive efficiency of females resulting from the treated larval was carried out according to Alhuraysi et al [21] . The females that successfully emerge from treated larvae were picked up and transferred with normal adult males (untreated) to the wooden cages (25×25×25 cm).…”

“…Furthermore, in the long run, populations are reduced through disrupted metamorphosis or reduced fecundity [28] . The differences in the toxicity of chemical plant compounds on target species depend on the part of the plant to be extracted and the solvent used for extraction, in addition to other differences due to species responses, the developmental stages in the specific extract, the plant geographic origin, photosensitivity to compounds in the extract, and the influence on development and reproductively [21,29] . Furthermore, crude or partially purified plant extracts have been shown to be less expensive and highly effective in controlling flies than the pure compounds [30,31] .…”

“…After 24 hours, the supernatant was filtrated and dried in a rotary evaporator at 45ºC. The dry extract was weighed and then kept in the refrigerator at 4°C until the experiments were performed [21] .…”

“…There are few studies interested with these plants, most of them have been performed on plant pests and few investigations have been done on medicinal and veterinary pests such as mosquito species. Although there are some references that are interested with flies causing myiasis control among animals in some regions of the world [18][19][20] , very few studies [21,22] are available on the control of flies causing myiasis in Kingdom Saudi Arabia. So, the present study was conducted to test the toxicity of Juniperus procera stem extracts on the larvae, pupae, adult, development, and female fecundity of C. albiceps.…”
