Etymology: "Adulticides" is the plural of "adulticide," a word formed in English from "adult" and the suffix "-cide," meaning "killing" (from Latin "caedere," to kill). The compound pairs "adult" with "-cide," so it reads literally as "adult-killing," and it is used for chemicals that target flying or mature insects rather than their larvae. The first element comes through a longer route than it looks. "Adult" was borrowed from Latin "adultus," the past participle of "adolescere," meaning "to grow up," and entered English through French "adulte." The Latin verb itself is built from "ad-" plus "alere," to nourish, so the sense of a grown creature that has been fed to maturity sits underneath the modern word.
