Abstract |
: |
Five plant oils including clove bud, Syzygium aromaticum, rosemary, Rosmarinus officinalis, sesame, Sesamun indicum, ginger, Zingiber officinale and black seed, Nigella sativa were extracted and used to evaluate the repellent activity, fumigant and surface contact toxicity against American cockroach, Periplaneta americana (L.). Clove oil showed highly significant repellency, fumigant and surface contact toxicity against the nymphal instars 1st and 4th and adult stages. While sesame oil exhibited only repellency and rosemary surface contact toxicity. Ginger and black seed oils were not affecting agents to the fourth nymph and adults, but showed only surface contact toxicity to the first nymph. The later was more sensitive than the fourth nymph followed by adults in all tested treatment methods. Concentrations were positively and highly significantly correlated with repellency and toxicity. Clove oil had more repellent effect than sesame oil and exhibited 100% repellency against the first and fourth nymphs at concentrations of 4 and 8% after 24h, respectively. Regarding the fumigant toxicity, first nymph was the most sensitive to clove oil by LC50 value (1.06µl/L of air) followed by fourth nymph (3.12µl/L of air) and adults (8.20µl/L of air) after 48h. Concerning surface contact toxicity, clove oil had the highest effect to first nymph followed by black seed, rosemary, sesame and ginger oils. Clove oil was more toxic than rosemary oil to first and fourth nymphs and adults. In conclusion clove oil can be used as botanical insecticide against P. americana applying as repellent, fumigant and surface contact methods, while sesame oil can be used only as repellent agent and rosemary oil as surface contact toxicity. Ginger and black seed oils were generally not affecting oils and exhibited only surface contact toxicity to first nymph. |
