paper V : Bugs, Cockroaches, Cyclops and Venomous arthropods

Unit I : Bugs: Reduvid bugs and bed bugs: Distribution, domiciliary forms and sylvatic forms; Modification of head size in relation to feeding - Structural and functional morphology and reproduction and life cycle - defecation – parasite transmission and disease spread

Unit II : Habitat – modification and prevention of breeding & environment and vector prolification - personal protection measures

Unit III : Cockroaches: Distribution and morphological characteristics ; Importance of cockroaches - mechanical carriers of parasite, pathogens - pest or disease vectors - and life cycle - feeding, resting behaviour - factors favouring breeding – Environmental and chemical control – feasibility and effectiveness; parasitoids and cockroaches

Unit IV : Cyclops: Distribution, morphology of Cyclops – Different species and vectors of dracuntiasis - and Aquatic habitats and breeding – life span – man and Cyclops – invasion and disease transmission - protected water supply and disease control – anti Cyclops measures - Control programme and achievements

Unit V : Venomous arthropods: Hazards posed by spiders, scorpions, ants, bees, wasps, urticating lepidopterans vesicating beetles, centipedes and millipedes
