Izvo zvinoshandiswa zvakare pheromone misungo, yakagadzirirwa kukwezva zvipfukuto zvechirume uye kuzvisiya zvakavharirwa, nokudaro zvichidzivirira kubereka kwazvo.

Aya matanho anovavarira ku kupedza denda uye kuidzivirira kubva pakuparadza nzvimbo hombe panorimwa bhokisi uye rinoshandiswa nenzira yekushongedza kuburikidza nekupararira kwayo. Ehezve, kuibvisa kwakanyanya kuomarara nekuti zvinoreva, pakutanga, kudzivirira kutengeswa kwezvimwe zvirimwa pakati penyika, chimwe chinhu chakanetsa kudzora.

Kucherechedzwa kweminda mikuru uye kuongororwa kwakakodzera panguva iyo kuvapo kwezvipembenene vanozoita musiyano mukubudirira mukurapa chipembenene kunyanya kana chikarwiswa muchikamu chayo chekutanga kana chizvarwa chekutanga chemabhu.

Kune avo vanokura munzvimbo diki uye dzinodzorwa, inokurudzirwa uye inoshanda chenesa bhokisi rega rega zvirinani kunyangwe idiki uye pavanenge vari muchikamu chavo chehusiku, tarisa zvakanaka uye utemhe nzvimbo dzese dzakakanganiswa, mwaka wechirimo usati watanga isa fetiraiza yakanaka izere nezvinovaka muviri inosimbisa chirimwa uye ichiibatsira kurwisa zvipfukuto uye kana zvichidikanwa isa mushonga wakachengeteka wemakemikari.

Chinhu chakakosha kurwisa tupukanana kubva pakutanga.
