Abstract: PONCE DE LEON, ESTRELLA : LUCAS, University of the Philippines at Los Bajios, September, 1983. Further Investigation of the Insecticidal Activity of Black Pepper (Piper nigrum L.) and Red Pepper (Capsicum annum L. on Major Storage Insect Pests of Corn and Legumes. Major Professor: Dr. Belen Morallo-Rejesus The insecticidal activity of ground black and red pepper on major storage insect pests of corn and legumes were further investigated. Both materials were toxic to Corcyra cephalonica (Staint), Calloso- bruchus chinensis (L.), and Acanthoscelides obtectus Say. Generally, black pepper was more toxic to the same test insects than the red pepper. Based on Mortality tests, the order of decreasing toxicity of black pepper to the test insects was: Cc. chinensis > A- obtectus >) C. cephalonica ) Ephestia cautella Hubn. > Oryzaephilus surinamensis (L.) > Sitophilus zeamais Mostch ) Rhizopertha dominica (Fab.) > Triboleum castaneum Herbst. In the red pepper: C. cephalonica > CC. chinensis >) _F. cautella )> 0. surinamensis 5} fT. castaneum > A. obtectus }) R. dominica } §.- zeamais. Black pepper and red pepper were more of a stomach poison than a contact poison, and they were residually toxic to the same storage pests, T. castaneum, R. dominica, and 0. surinamensis for four and two months respectively. Black and red pepper wére also residually toxic to C. chinensis and_A. obtectus for six months, except the former was residually toxic to A. obtectus for two months only. Likewise, both were not residually toxic to the two lepidopterous storage pests, C. cephalonica and E. cautella. Furthermore, the two materials tested had also exhibited growth inhibitory activity on the storage insect pests studied.

PONCE DE LEON, ESTRELLA : LUCAS, University of the Philippines at Los Bajios, September, 1983. Further Investigation of the Insecticidal Activity of Black Pepper (Piper nigrum L.) and Red Pepper (Capsicum annum L. on Major Storage Insect Pests of Corn and Legumes. Major Professor: Dr. Belen Morallo-Rejesus

The insecticidal activity of ground black and red pepper on major storage insect pests of corn and legumes were further investigated. Both materials were toxic to Corcyra cephalonica (Staint), Calloso- bruchus chinensis (L.), and Acanthoscelides obtectus Say. Generally, black pepper was more toxic to the same test insects than the red pepper. Based on Mortality tests, the order of decreasing toxicity of black pepper to the test insects was: Cc. chinensis > A- obtectus >) C. cephalonica ) Ephestia cautella Hubn. > Oryzaephilus surinamensis (L.) > Sitophilus zeamais Mostch ) Rhizopertha dominica (Fab.) > Triboleum castaneum Herbst. In the red pepper: C. cephalonica > CC. chinensis >) _F. cautella )> 0. surinamensis 5} fT. castaneum > A. obtectus }) R. dominica } §.- zeamais.

Black pepper and red pepper were more of a stomach poison than a contact poison, and they were residually toxic to the same storage pests, T. castaneum, R. dominica, and 0. surinamensis for four and two months respectively. Black and red pepper wére also residually toxic to C. chinensis and_A. obtectus for six months, except the former was residually toxic to A. obtectus for two months only.

Likewise, both were not residually toxic to the two lepidopterous storage pests, C. cephalonica and E. cautella.

Furthermore, the two materials tested had also exhibited growth inhibitory activity on the storage insect pests studied.
