AbstractA resume is made of the major sequences of egg-laying behaviour, both in nature and on stored seeds, of the bean weevil. An experimental analysis of the role of the ovipositor in the act of egg-laying is then undertaken by simple techniques. It is observed that an important stimulus, with respect to this, is mechanical in nature: resulting from contact between the setae of the ovipositor on the one hand, and the seed and the "ground" on the other. Simply suspending the seed instead of leaving it lie on the cage bottom, suffices to reduce egg-laying and production significantly. Examination of egg-laying, when the substratum furnished is a trellis with suitable sized mesh, shows that an important aspect of the mechanical stimulus is in its concentrical character, i.e., the fact that it is applied to a greater number of setae all around the ovipositor. The result enables us to understand better the behaviour in nature, where there is a boring of the bean pod followed by egg-laying inside that pod through through the hole made. In the course of the paper some connected problems are evoked: - The relationship between egg-laying and production; - The more or less necessary character of the succession of the different sequences in egg-laying behaviour. Existence of intermediary cases, between individuals which can lay eggs only in the pod and those laying in the apparent absence of any stimulus, particularly stimuli connected with the bean; - Links between the phytophage and its host, remarks on the apparently unfavourable peculiarity of laying a great number of eggs in the same place, the possible consequences with respect to population dynamics.

Contact Insecticides

Effects of contact insecticides pirimifos-methyl and deltamethrin of Indian meal moth Plodia interpunctella Hbn. and Angoumois grain moth Sitotroga cerealella Oliv. in maize, and on bean weevil Acanthoscelides obtectus Say in beans were examined 6 and 18 months after treatment in laboratory environment. Using appropriate methods (EPPO and other), maize and bean were treated with recommended and double rates of the insecticide products: EC formulation of pirimifos-methyl and EC formulation and dust of deltamethrin. After 6 and 18 months, we examined the mortality of P. interpunctella larvae, and 5. cerealella and A. obtectus adults following 2,7 and 14 days of contact with the treated material. In Angoumois grain moth and bean weevil, the resulting progeny was monitored up to FI generation. Both insecticides achieved full mortality of P. interpunctella larvae on the 6-month-old deposit. On the 18-months-old deposit, the same result was achieved with deltamethrin dust (both rates), as well as with pirimifosmethyl and deltamethrin (EC formulation) at the double recommended rates. S. cerealella mortality was 100% for both insecticides and both deposit ages. Regarding A. obtectus, full mortality of adults was found after contact with pirimifos-methyl and deltamethrin dust, while deltamethrin liquid caused low mortality of bean weevil, especially the 18-months-old deposit. FI generation adults of Angoumois grain moth and bean weevil were found only on 18-months-old deposits of the recommended rates of deltamethrin dust and pirimifos-methyl. The tested contact insecticides can provide very long prevention and control of Indian meal moth and Angoumois grain moth in stored maize and bean weevil in stored beens.
