Abstract

The pesticidal properties of different seed extracts contained in the green fruit of the papaya tree Carica papaya L. (Caricaceae) were tested on the species of termite pest Macrotermes bellicosus. The effect of the alcoholic extract of the seeds is the most toxic and that of the aqueous extract the least (LD50 of 0.15 ± 0.0 mg/L and 23.5 ± 0.0 mg/L respectively). Contact is one of the essential factors for the effectiveness of the extract but it does not act by ingestion and it inhibits food intake by the termite. The study of toxicity on mammals indicates that the aqueous extract is non-toxic (LD50>5000 mg/Kg/bw). However, the study of the effects of the extract on male fertility shows that sperm parameters are altered 2 weeks after treatment. The use of papaya as a bioinsecticide can be justified satisfactorily but under control.
