Pest : Spider MitesSpider mitesare little , 8 legged , spider - like puppet which prosper in blistering , juiceless conditions ( like het houses ) . Spider mite flow with piercing backtalk parts , which induce industrial plant to appear yellow and stippled . Leaf drop-off and plant life decease can occur with heavy infestations . wanderer mites can manifold promptly , as a female can lay up to 200 nut in a animation span of 30 day .
