- Why are mosquitoes technically considered to be aquatic insects?Give three reasons why tilapia does not stay in the seaWhy might farmers and gardeners be concerned about nematodes? A. Some for "tent like" egg cases in trees, then the caterpillars that eat many of the leaves B. Some of they chew on roots, hurting the plants C. Pesticides kill the good nematodes and then the soil gets too compacted D. They are a beneficial natural way of controlling slugs because they parasitize slug eggs
- What are the differences in the life cycle of mosquitoes and butterflies?It has been found that many insect pest populations have become more resistant to pesticides over time. How might this have occurred? Which is a correct statement concerning the insect circulatory system? Question 18 options: A) Blood transports oxygen and nutrients to all the tissues B) Blood is always contained in a system of tubes called tracheae C) The circulating fluid bathes tissues directly D) There is no heart, or pump
- Pyrethroids are toxic to the nervous system in humans. What is the biological effects on the insects that is used against and how it is metabolized to kill off the organism? Contrast this with any known or theorized harmful effects it could have on humans or our environment.You are trying to develop a new anti-termite chemical that will not harm environmentally beneficial insects. Because termites are adapted to eat only wood, they will starve if they cannot digest this food source. Termites have two symbiotic partners: the protozoan Trichonympha collaris and the bacteria it harbors that actually produce the enzyme that digests the wood. Knowing this, how might you prevent termite infestations without targeting the termites directly?When a pseudoscorpion hitches a ride on a large arthropod, what does the larger arthropod gain from the interaction? a.) Food b.) Protection c.) Dispersal d.) Nothing e.) Friends

Is there a relationship between the size of the insect and the level of defense?Which row below best describes why the population of adult mosquitoes would drop so dramatically during this time period Feb. 5, 2007 Something is wiping out honey bees across North America and a team of researchers is rushing to find out what it is. What’s being called Colony Collapse Disorder (CCD) has now been seen in Pennsylvania, North Carolina, Florida, Georgia and way out in California. Some bee keepers have lost up to 80 percent of their colonies to the mysterious disorder. Whatever kills the bees targets adult workers, which die outside the colony — with few adults left inside, either alive or dead. The disorder decimates the worker bee population in a matter of weeks. Aside from making honey, honey bees are essential for the pollination of tens of million of dollars worth of cash crops all over the United States. That’s why almond growers of California, for instance, are taking notice and pledging funds to help identify and fight the honey bee disorder. Among the…
