Funkce sekrec\u00ed<\/h3>\n
    \n
  1. Obrana:<\/strong> Mnoho druh\u016f hmyzu produkuje repelenty nebo toxiny, kter\u00e9 je chr\u00e1n\u00ed p\u0159ed pred\u00e1tory. P\u0159\u00edkladem mohou b\u00fdt jedovat\u00e9 sekrety brouk\u016f prskavc\u016f nebo p\u00e1chnouc\u00ed sekrety plo\u0161tic.<\/li>\n
  2. Komunikace:<\/strong> Feromony jsou chemick\u00e9 sign\u00e1ly, kter\u00e9 hmyz vyu\u017e\u00edv\u00e1 ke komunikaci. Slou\u017e\u00ed k p\u0159il\u00e1k\u00e1n\u00ed partnera, zna\u010den\u00ed teritoria nebo varov\u00e1n\u00ed p\u0159ed nebezpe\u010d\u00edm.<\/li>\n

  4. Z\u00edsk\u00e1v\u00e1n\u00ed potravy:<\/strong> N\u011bkter\u00e9 druhy hmyzu, nap\u0159\u00edklad m\u0161ice, produkuj\u00ed medovici, sladkou tekutinu, kter\u00e1 l\u00e1k\u00e1 mravence, kte\u0159\u00ed je na opl\u00e1tku chr\u00e1n\u00ed p\u0159ed pred\u00e1tory.

  5. Termoregulace:<\/strong> N\u011bkter\u00e9 sekrety mohou hmyzu pom\u00e1hat s termoregulac\u00ed, nap\u0159\u00edklad voskov\u00fd povlak na kutikule sni\u017euje ztr\u00e1ty vody.<\/li>\n<\/ol>\n
