IPA: /ˈlɑːrvɪˌsaɪd/
KK: /ˈlɑːrvɪˌsaɪd/
A substance used to kill the larval stage of insects, especially pests that can harm crops or spread disease.
Farmers often use larvicides to protect their crops from harmful insect larvae.
Larvicide → It is formed from "larva" (from Latin *larva*, meaning ghost or mask, but in biological terms refers to the immature form of an insect) and "-cide" (from Latin *caedere*, meaning to kill). The word "larvicide" refers to a substance that kills larvae, particularly those of insects.
Think of a substance that 'kills' ('-cide') the 'larvae' ('larva') of insects — that's what larvicide means.
