The present invention relates to a novel agricultural pesticidal composition. In particular, the present invention provides a pesticidal composition comprising combination of an insecticide and plant health promoting agent. The said combination is highly suitable for controlling unwanted animal pests, such as insects, acaricides and/or nematodes, and unwanted phytopathogenic fungi.

The disclosure discloses a Chinese cabbage plasma membrane intrinsic aquaporin, having an amino acid sequence as set forth in SEQ ID NO. 2, and the nucleotide sequence of the encoding gene BraPIP2;1 thereof is as set forth in SEQ ID NO. 1. The plasma membrane intrinsic aquaporin has the characteristic of sensitively responding to neonicotinoid insecticides (thiamethoxam, imidacloprid, etc.) in the external environment. At the same time, it has the function of mediating transmembrane transport of the neonicotinoid insecticides, promoting accumulation of the neonicotinoid insecticides in plant roots and leaves, which has important application value in guiding efficient and simple use of pesticides, development of new systemic pesticides, etc.

An object of the present invention is to provide a method which does not have a problem with safety and enables controlling various pests even at a low dosage, and a pest control agent composition and a pest control agent set which are suitable to be used for the method. In the pest control method of the present invention, at least one compound selected from a compound of formula (I) (wherein, in formula (I), R.sup.1 represents a substituted or unsubstituted C1-6 alkylthio group, a substituted or unsubstituted C1-6 alkylsulfinyl group, or the like, R.sup.2 represents a hydrogen atom or a substituted or unsubstituted C1-6 alkyl group, R represents a C1-6 haloalkyl group or a C2-6 haloalkenyl group, X represents a substituted or unsubstituted C1-6 alkyl group, a substituted or unsubstituted C2-6 alkenyl group, or the like, n represents any integer of 0 to 4, and Xs are the same or different when n is 2 or more) and a salt thereof is applied with an insecticidal or acaricidal active component to an object.
