Flying Into the Wind (1 Letter) Re "A Low-Tech Mosquito Deterrent" (July 16): As students at the Indian Institute of Technology, Kharagpur, (near Kolkata) in the late 1960s, without air conditioning, we learned the hard way that mosquito nets hindered the much-needed breeze from our ceiling fans. I never used a net, and was rarely bitten; a strong fan set at high was better than any repellent. But dorm-lore had it that the females had evolved a strategy of flying hard into the breeze and being blown onto the bed below, then crawling slowly to a blood-banquet. The occasional sated mosquito was found squashed on our sheets in the morning - not reliable evidence, but there it is. Krishna Ramaswamy Philadelphia
