Abstract: The invention relates to the use of azine derivatives, some of which are known, of the formula ##STR1## in which A represents substituted phenyl, or represents in each case optionally substituted naphthyl, pyridyl, thienyl or pyrazolyl;B represents hydrogen, alkyl or in each case optionally substituted phenyl, phenylalkyl, phenylalkenyl, phenoxyalkyl, phenylthioalkyl, phenylsulfinylalkyl or phenylsulfonylalkyl;D represents hydrogen or alkyl;E represents hydrogen, alkyl or in each case optionally substituted phenyl, phenylalkyl, phenoxyalkyl, phenylthioalkyl, phenylsulfinylalkyl or phenylsulfonylalkyl;G represents hydrogen or alkyl;J represents hydrogen or alkyl;K represents hydrogen, alkyl or optionally substituted phenyl; orB and D or D and G or E and G together represent optionally substituted alkanediyl, wherein one or two CH.sub.2 groups are optionally replaced by O and/or S; andW and Y are different and represent N, O or S, wherein the ring always contains an N atom,for combating animal pests.

Abstract: 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, andR.sup.2 represents a fluorine atom or a chlorine atom.The insecticidal and miticidal agent exhibits an excellent insecticidal and miticidal activity against harmful insects and mites parasitic on useful plants.

Abstract: 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;R.sub.3 represents a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group;R.sub.

Abstract: 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.

Abstract: A compound of the general formula ##STR1## wherein X.sub.1 represents a hydrogen, fluorine, chlorine or bromine atom, X.sub.2 represents a fluorine, chlorine or bromine atom, R represents a hydrogen atom or a lower alkyl group, and Y represents a fluorine, chlorine or bromine atom, or a trifluoromethyl or cyano group.This compound is prepared by reacting a compound of the formula ##STR2## or a reactive derivative thereof with a compound of the formula ##STR3## and is useful as an insecticide.
