Microcapsules formed from an aminoplast shell wall and an encapsulated ingredient or ingredients enclosed within the wall in which the wall contains a base-cleavable ester moiety. These capsules have been found to be sensitive to the presence of base such that in the presence of base, the capsule walls are relatively quickly disintegrated or degraded so as to produce a relatively quick release of the encapsulated materials. Microcapsules of this invention are particularly suitable for use in controlling insects having an alkaline gut such as certain lepidoptera in that the capsule shell wall may be designed so as to quickly disintegrate under the alkaline conditions present in the gut of the insect thus providing a microcapsule which is safe to handle but which is selectively effective against certain undesirable insects while not harmful to beneficial insects or insects which do not feed on the capsule materials.

L'invention concerne des microcapsules à coque en paroi aminoplaste, renfermant un ou plusieurs éléments encapsulés dans la paroi, sachant que la paroi renferme elle-même une fraction ester clivable par base. Les microcapsules sont sensibles à la présence d'une base, moyennant quoi la présence de cette base désintègre ou dégrade rapidement la paroi. Cela entraîne la libération rapide des éléments encapsulés. Les microcapsules en question sont particulièrement utiles pour la lutte contre les insectes à boyaux alcalins, comme certains lépidoptères. Ainsi, on peut concevoir les microcapsules pour que leur paroi se désintègre rapidement sous l'effet des conditions alcalines présentes dans les boyaux des insectes. En l'occurrence, les microcapsules offrent une manipulation fiable tout en étant efficaces contre certains insectes indésirables et en ne nuisant pas aux insectes utiles ou aux insectes qui n'absorbent pas les éléments encapsulés.
