Lloyd Pest Control University Quiz LPC U Quiz Think you've got what it takes to be a pest control profession? Take this quiz and find out.1. What is the Mode of Action for the Pyrethroid group of chemistry?* It binds to nicotinic acetylcholine receptors (nAChRs) of a cell and triggers a response by that cell. It inhibits de novo purine synthesis at the regulatory sites PRPP-amido transferase, IMP dehydrogenase as well as dihydrofolate. It blocks off nerve sodium channels. It prevents the closure of the voltage-gated sodium channels in the axonal membranes. 2. Flies in the Family Phoridae (Scuttle flies) can be identified by which description?* Tiny black, brown, or yellowish flies with a humped back, a low small head, and dark eyes; costal vein extends only about halfway along anterior wing margin; two strong longitudinal veins anteriorly (in costal area), and 4-5 weak veins posteriorly, not connected by cross-veins; hind femora enlarged and flattened, and hind legs long; antennae appear 1-segmented. They are recognized by the structure of the subcosta which bends apically forward at almost a right angle and then fades out. The eyes reddish; mouthparts sponging; dorsum of thorax with four narrow black stripes; sharp upward bend in fourth longitudinal wing vein (M1+2) which almost touches vein R4+5 at the wing margin. The underside of male yellowish; female eyes far apart, separated by broad ovoid frontal stripe that occupies more than half the distance between the eyes; male eyes close together, separated by narrow frontal stripe (distance between eyes in female almost 2x distance between eyes in male). Wings with scales on veins and along margins; legs and proboscis long; antennae with 6 or more segments, plumose on males and short-haired on females. 3. Rice weevils can be identified by which description?* Small snout beetle which varies in size, but it averages about three thirty-seconds of an inch in length. It varies from reddish brown to nearly black and is usually marked on the back with four light-reddish or yellowish spots. The thorax is densely pitted with somewhat irregularly shaped punctures, except for a smooth, narrow strip extending down the middle of the upper (dorsal) side. A slightly larger weevil, up to one-eighth of an inch long, and darker than most weevils. The thorax is densely and uniformly pitted with round punctures. It is a common pest of a variety of grain crops and causes tremendous losses to corn in the South, reducing the kernels to dry powder and hulls. A small, dark-brown snout beetle slightly less than one-eighth of an inch long. It differs from other grain-infesting weevils by having a shorter, broader snout A very active, robust, dark-brown beetle two-sixteenths to three-sixteenths of an inch long. It is covered with a mottled light- and dark-brown pubescence. This weevil is found in many countries and is extremely abundant in the Southern States, where it breeds in dried fruit, coffee berries, cornstalks, corn, and the seed and seed pods of an almost endless variety of plants. 4. This group of insects has flight muscles attached directly to the wings, as opposed to other insects that have the flight muscles attached to the thorax, making it oscillate and indirectly causing the wings to beat.* Coleopteran Odonatans and Ephemeropterans Collembolans Hymenopterans 5. Arachnid bodies are divided into these two main parts.* Cephalothorax & abdomen Mesothorax & metathorax Thorax & abdomen Tergite & prothorax 6. Males in the family Culicidae have this type of antennae.* Filiform Geniculate Lamellate Plumose 7. Which organism played a role in spreading the “Bubonic Plague” in Europe in the 1700’s?* Roof rat Oriental rat flea Yersinia pestis bacteria All of the above 8. Bed Bugs can be identified by which of the following descriptions?* Reddish-brown body, ovoid, broadly flattened, with greatly reduced wings; forewings (hemelytra) broader than long, somewhat rectangular; sides of pronotum covered with short stiff hairs (fringe hairs on pronotum shorter than width of eye). May be identified by two tube-like projections on the posterior, called cornicles or siphunculi. Either mottled or solid color body varying from pale green to reddish-brown or black with pale Y or V shape on scutellum; antennae and legs relatively long. None of the above 9. Argentine ants can be identified by which of the following descriptions?* A worker that is usually uniformly light to medium brown (can seem almost black if not viewed up close); body slender; head oval to triangular-shaped; mandibles with two large apical teeth followed by series of denticles; alitrunk dorsum normally lacking erect hairs; petiole erect. Red front end, dark brown to black rear end. Two nodes attach the abdomen to the thorax Long propodeal spines, broad square head, and fine, fingerprint-like cephalic rugosity. None of the above 10. In a subterranean termite colony; which caste is commonly known as swarmers?* Workers Soldier Supplementary reproductives Primary reproductives Δ
