Ch.1 List the general kinds of damage insect pests can cause -
CORRECT ANSWER- -Chew on seeds, roots, leaves, stems, & fruits
-Tunnel in roots, stems, & leaves
-Suck plant juices
-Promote gall formation and other malformations
-Inject toxins into plants -Transmit diseases to plants
-Create a nuisance for people
Ch.1 Describe the structural features of insects - CORRECT
ANSWER- Insects have: body form has 3 regions: head, thorax,
abdomen; 3 pairs of legs attached to thorax; 0, 1, or 2 pairs of wings
attached to thorax; 1 pair of antennae
Ch.1 Explain how to distinguish insects from other arthropods -
CORRECT ANSWER- Arthropods have: exoskeleton; body form has 2
regions: head & abdomen; usually 4 pairs of legs attached to head; no
wings; no antennae
,Ch.1 Contrast the difference between simple and complete
metamorphosis - CORRECT ANSWER- -Simple: "Incomplete
Metamorphosis"; 3 stages: egg, nymph, & adult
-Complete: 4 distinct stages: egg, larva, pupa, & adult
Ch.1 Explain how temperature and humidity affect insect development -
CORRECT ANSWER- *Temperature & humidity preferences vary for
each insect.
*Combined effect of both on reproduction & development is more
dramatically different than the effect of either alone.
-Temperature: development is faster with heat & slower with cold
temps; insects die at the high levels of developmental threshold temps
and become inactive at low levels
-Humidity: effects insect diseases; effects moisture levels required for
survival
Ch.1 List the advantages and disadvantages of using insecticides -
CORRECT ANSWER- Advantages:
-Effective against economically damaging pests
-Can combine 1 or 2 insecticides to combat several pests
-They act quickly to control pests before reaching damaging levels
-For new pests, there are many compounds that have been proven
effective
,-Effective insecticides, suitable formulations, & application equipment
are normally available
Disadvantages:
-Often eliminate beneficial insects, allowing target organisms to rebound
quickly
-Repeated exposure can lead to resistance in a pest population
-Yearly dependence on applications is an added cost
-Always a potential for drift, residues, and damage
Ch.2 Explain what determines whether a given plant is a weed -
CORRECT ANSWER- Weeds are unwanted plants
Ch.2 List the two main goals of weed management - CORRECT
ANSWER- 1. Minimize weed competition
2. Limit the weed's reproduction so that you can still manage the weed
population in future years
Ch.2 Describe ways that weeds can pose problems in turf and landscapes
(7) - CORRECT ANSWER- -Interfere with management practices
-Produce chemical inhibitors that directly retard the growth of desirable
plants (allelopathy)
-Create a poor impression on customers
-Interferes with pesticide applications
-Support insect pests and plant diseases or provide cover for rodents
, -Are poisonous, allergenic, or irritating to people or pets
-Dry out or die and become fire hazards
Ch.2 Distinguish grasses from broadleaf plants and woody from
herbaceous plants - CORRECT ANSWER- -Grasses (Monocots): most
common weeds; have a single seed leaf (cotyledon) when they
germinate; narrow leaves with parallel viens
-Broadleaves (Dicots): have 2 seed leaves when they germinate; veins
form a net-like or branching pattern; can be broken down into Woody
and Herbaceous plants
--> Woody: have thickened outer layer on stems (bark)
--> Herbaceous: lacks bark
Ch. 2 Describe the life cycles and propagation of annual, biennial, and
perennial plants - CORRECT ANSWER- -Annuals: live less than 12
months; most seeds germinate the following year, some are dormant
taking several years; prolific seed producers.
--> Summer Annuals: germinate from seed in spring, flower/produce
seeds in summer, die in late summer/early fall.
--> Winter Annuals: germinate from seed in fall, overwinter as low-
growing plants, flower/produce seeds in spring, then die.
-Biennials: live for 2 growing seasons; germinate from seeds in spring or
summer and produce a rosette of leaves, overwinter in rosette stage,
flower the following year, produce seed, and die.
