This invention provides an insecticidal and miticidal agent which contains as an effective ingredient an oxazoline derivative represented by the formula ##STR1## wherein, R.sup.1 represents a fluorine atom, a chlorine atom, a C.sub.1 to C.sub.3 alkyl group or a C.sub.1 to C.sub.3 alkoxy group, and

Oxazoline derivatives, insecticidal and miticidal composition, and

Acaricide

2-(2,6-difluorophenyl)-4-(2-ethoxy-4-tert-butylphenyl)-2-oxazoline

The invention provides an insecticidal and miticidal composition containing 2-(2,6-difluorophenyl)-4-(2-ethoxy-4-tertiarybutylphenyl)-2-oxazoline and at least one compound selected from the specific pyrethroid compounds, as its active ingredients. The present composition can protect useful plants from various kinds of noxious insects and mites such as Aphididae and Acarina in small application amounts.

Insecticidal and miticidal composition

2-Substituted phenyl-2-oxazoline derivatives or 2-substituted phenyl-2-thiazoline derivatives represented by the general formula (I) ##STR1## in which R.sub.1 and R.sub.2 may be same or different and each represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a nitro group, a lower haloalkyl group or a lower haloalkoxy group, with a proviso that R.sub.1 and R.sub.2 do not simultaneously represent hydrogen atoms;

2-Substituted phenyl-2-oxazoline or thiazoline derivatives, process for

A compound represented by the following formula ##STR1## wherein X.sup.1 and X.sup.2 are identical or different and each represents a hydrogen atom, a lower alkyl group, a lower alkoxy group, a halogen atom, a trifluoromethyl group or a trifluoromethoxy group;

Oxa- or thia-zoline derivative

A compound represented by the formula ##STR1## wherein R represents an alkyl group having 7 to 11 carbon atoms, a phenyl group which may be substituted by a lower alkyl group or a halogen atom, or a group of the formula ##STR2## in which X represents a hydrogen or halogen atom. This compound can be prepared by reacting a compound represented by the formula ##STR3## wherein m is an integer of 1 to 2, and Y represents a chlorine atom when m is 1 and --O-- when m is 2, with a compound represented by the following formula ##STR4## wherein M represents a hydrogen or alkali metal atom; and is useful as a miticide.
