Chagas disease is caused by infection with the protozoan parasite T. cruzi, which is typically introduced into humans through the bite of triatomine bugs, also called "kissing bugs". [4] When the insect defecates at the bite site, motile T. cruzi forms called trypomastigotes enter the bloodstream and invade various host cells. [ 5 ]
Thread-legged bugs – subfamily Emesinae, including the genus Emesaya Kissing bugs (or cone-headed bugs) – subfamily Triatominae , unusual in that most species are blood-suckers and several are important disease vectors
The disease begins with weakness, blurred vision, feeling tired, and trouble speaking. This may then be followed by weakness of the arms, chest muscles, and legs.

Canthariasis infections transmitted to humans by the cigarette beetle has been reported in China and Malaysia .
Ergot infection causes a reduction in the yield and quality of grain and hay, and if livestock eat infected grain or hay it may cause a disease called ergotism. Black and protruding sclerotia of C. purpurea are well known. However, many tropical ergots have brown or greyish sclerotia, mimicking the shape of the host seed.
Stings are usually located at the rear of the animal. Animals with stings include bees, wasps (including hornets), some ants like fire ants, and scorpions, [2] [3] as well as a single beetle species (Onychocerus albitarsis) that can deliver a venomous sting from its antennae, whose terminal segments have evolved to resemble a scorpion's tail. [4]
Each beetle contains some 0.2–0.7 mg of cantharidin, males having significantly more than females. The beetle secretes the agent orally, and exudes it from its joints as a milky fluid. The potency of the insect as a blistering agent has been known since antiquity and the activity has been used in various ways.
