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: 2-(2,6-difluorophenyl)-4-(2-ethoxy-4-tert-butylphenyl)-2-oxazoline. This compound is useful as miticide.

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 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;Y.sup.1 and Y.sup.2 are identical or different and each represents a hydrogen atom, a lower alkyl group, a lower alkoxy group, a lower alkylthio group, a cyano group, a nitro group, a halogen atom or a trifluoromethyl group;Z represents an oxygen or sulfur atom; andn is 0 or 1;excepting the case where n is 0 and X.sup.1 and X.sup.2 are both hydrogen atoms, the case where n is 1 and X.sup.1 and X.sup.2 are members selected from the class consisting of hydrogen and halogen (excepting iodine) atoms, and the case where Y.sup.1 and Y.sup.2 are membrs selected from the class consisting of hydrogen and halogen (excepting iodine) atoms and nitro groups. This compound is useful as an insecticidal and acaricidal (miticidal) agent.
