This study aimed to determine the potency of ethanolic extract of papaya leaf as toxicant and repellent against 2 populations of German cockroaches which are known resistant to synthetic insecticide. Materials and Methods: The methods that used was contact toxicity test and repellency test. The ethanolic extract of papaya leaf residues were used in contact toxicity test of 4 residues and a sub-lethal residue in repellency test. Three populations of German cockroach were collected in field and kept in laboratory. Results: Lethal residue 50% (LR50) of ethanolic extract of papaya leaf between 2.97-4.72 mg cm2 while lethal residue 90% (LR90) between 6.05-8.92 mg cm2 and very effective killed all population of German cockroach. Repellency value of ethanolic extract of papaya leaf with a sub-lethal residue of 0.39 mg cm2 between 88.89 -94.74% and level of repellency was very repellent. Conclusion: Ethanolic extract of papaya leaf could be formulated as a potent natural insecticide to control populations of German cockroach that have been resistant to synthetic insecticides.]]>Chai, R.Y. and C.Y.
