In crop production in the fields of agriculture, horticulture and the like, the damage caused by insect pests etc. is still immense, and insect pests resistant to existing insecticides have emerged. The present invention has been made in view of such circumstances, and an object of the present invention is to develop and provide a novel agricultural or horticultural insecticide. Another object of the present invention is to provide an agent capable of eliminating ectoparasites or endoparasites of animals. These objects are achieved by an imidazopyridazine compound having a substituted cyclopropane-oxadiazole group represented by the general formula (1):

[Chem. 1]

##STR00001##

(wherein R.sup.1 preferably represents an alkyl group, R.sup.2a and R.sup.2b each represent a hydrogen atom, and R.sup.3 represents a haloalkyl group) or a salt thereof, an agricultural or horticultural insecticide or an animal ectoparasite or endoparasite control agent each comprising the compound or the salt thereof as an active ingredient, and a method for using the compound or the salt thereof, the insecticide, or the control agent.

Described herein are bee-safe acaricides that target the varroa mite-specific neuropeptidergic system regulated by proctolin, and methods of use. The acaricides comprise a peptide analog or peptidomimetic of varroa mite proctolin for selective targeting of this pest in a bee colony. The compounds are also effective against other pests, such as ticks. The peptide analog or peptidomimetic generally comprises one or two amino acid residue substitutions or insertions. Also described herein are methods of screening compounds for activity on a proctolin receptor.
