Twenty-five chemicals active as, or related to, 2-acetylpyridine thiosemicarbazones were investigated for their repellency and toxicity to red-winged blackbirds (Agelaius phoeniceus) and toxicity to starlings (Sturnus vulgaris). Two chemicals (1-azetidinecarbothioic acid (1-(2-pyridinyl)ethylidene)hydrazide and 1-pyrrolidinecarbothioic acid (1-(2-pyridinyl)ethylidene)hydrazide) were about twice as repellent to redwings and from 1/2 to 1/3 as toxic as methiocarb, the most effective bird repellent currently registered in the United States. The repellency of a third chemical, methyl (1-(2-pyridinyl)ethylidene)hydrazinecarbodithioate, was similar to that of methiocarb but it was almost 100 times less toxic to redwings than methiocarb and was 20 to 50 times less toxic than related thiosemicarbazones. Twenty-two other chemicals were not effective repellents or toxicants for redwings or toxicants for starlings. |
