Host specificity studies on Ceutorhynchus maculaalba, a potential candidate for the biological control of opium poppy



Host specificity studies on Ceutorhynchus maculaalba, a potential candidate for the biological control of opium poppy



Environmental Entomology, 95: 681-688



C. maculaalba (Herbst), was studied as a possible biological control agent against opium poppy, P. somniferum [a plant long cultivated for medicinal purposes]. The adult makes oviposition punctures in the capsules causing damage and loss of latex. Later, the larva feed in the capsules and destroy the seeds. Host specificity tests to ascertain the safety of the weevil using 114 plant species or varieties in 20 families were made at the Rome Laboratory. Feeding was found on plants in most families tested; the highly specialized ovipositional behavior indicates that the insect is specific enough to be used in a biocontrol program.
