Ch.1 Explain how temperature and humidity affect insect development -

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 general kinds of damage insect pests can cause -

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 - 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 -

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 - ANSWER- -Simple: "Incomplete Metamorphosis"; 3

stages: egg, nymph, & adult

-Complete: 4 distinct stages: egg, larva, pupa, & adult

Ch.1 List the advantages and disadvantages of using insecticides -

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 -

ANSWER- Weeds are unwanted plants

Ch.2 List the two main goals of weed management - 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) - 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 - 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 - 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 lowgrowing 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.

-Perennials: live for at least 2 years, sometimes longer; may reproduce

by seed or spread vegetatively (stolons, rhizomes, spreading roots,

tubers, bulbs)
