Insecticide formulations having improved chemical and physical stability and related methods are disclosed. The insecticide formulations may include a plurality of microcapsules, each including at least one organophosphate insecticide (e.g., chlorpyrifos methyl) at least partially surrounded by a polymer shell. The insecticide formulations may be used to control insect populations by singular or periodic applications. The microcapsule polymer shell of the insecticide formulations may be formed by combining a cross linking amine and a hydrophobic monomer (e.g., an isocyanate) at a molar ratio of amine to isocyanate groups of less than about 1:1.

The invention provides a frameless photo-energy assembly including a photo-energy converter, wherein an edge of the photo-energy converter is sealed by an adhesive tape, comprising an adhering layer for adhesion and cushioning; and an aging-resistant protective layer. The adhering layer is used to contact the edge of an article and comprises: a substrate layer; optionally, a first adhesive layer and a second adhesive layer situated at both sides of the substrate layer oppositely, wherein the first adhesive layer being used to be contact with the article. The aging-resistant protective layer is situated on the adhering layer, which comprises: an optional primer layer, which is situated on the adhering layer; and a film layer, which is situated on either the primer layer or the substrate or the second adhesive layer. The invention further provides an adhesive tape for sealing an edge of an article and an article made of the assembly. Se describen formulaciones insecticidas que tienen una estabilidad física y química mejorada así como métodos relacionados con las mismas. Las formulaciones insecticidas pueden incluir una pluralidad de microcápsulas, cada una incluye al menos un insecticida organofosforado (por ejemplo clorpirifos-metilo) al menos parcialmente rodeado por una cubierta de polímero. Las formulaciones insecticidas se pueden utilizar para controlar las poblaciones de insectos por aplicaciones singulares o periódicas. La cubierta de la microcápsula de polímero de las formulaciones insecticidas puede ser formada combinando una amina reticulante y un monómero hidrófobo (por ejemplo un isocianato) en una relación molar de grupos amina a isocianato de menos de aproximadamente 1:1.
