Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a highly safe pesticide-containing microcapsule whose capsule shell wall is designed so as to quickly disintegrate under the alkaline condition present in an insect gut. SOLUTION: In the pesticide-containing microcapsule, a pesticide is encapsulated in a polymeric shell wall formed by interfacial polymerization and condensation of a mixture of a butylated urea-formaldehyde prepolymer and a cross-linking agent containing sulfhydryl groups and hydroxyl groups, such as a glycolate ester and a mercapto carboxylic acid ester of pentaerythritol.
