CORE exam questions with correct answers
Explain |the |difference |between |key |pests, |occasional |pests |and |secondary |pests |- |CORRECT |
ANSWER✔✔-Key |pests |are |nearly |always |present |and |require |regular |control. |occasional |pests
|are |migratory |or |cyclical |and |require |intermittent |control. |secondary |pests |require |control |
only |under |certain |conditions, |such |as |the |elimination |of |a |key |pest |or |the |absence |of |a |
natural |host.
what |should |you |do |first |if |you |see |damage |to |a |plant, |animal, |or |valuable |product/ |- |
CORRECT |ANSWER✔✔-identify |the |cause
what |should |you |do |first |if |you |discover |a |pest |that |may |need |to |be |controlled? |- |CORRECT |
ANSWER✔✔-make |sure |the |pest |is |actually |responsible |for |the |damage. |then |accurately |
identify |the |pest
how |can |pest |identification |help |you |develop |a |good |pest |control |strategy? |- |CORRECT |
ANSWER✔✔-it |allows |you |to |determine |basic |information |about |the |pest, |including |its |life-
cycle |and |when |it |is |most |susceptible |to |control |measures.
name |the |5 |basic |pest |groups |- |CORRECT |ANSWER✔✔-weeds, |parasites |and |diseases, |
mollusks, |arthropods, |and |vertebrates.
why |do |weeds |present |such |a |challenge |to |pest |managers? |- |CORRECT |ANSWER✔✔-weeds |
are |often |hardy, |aggressive, |and |tolerant |of |harsh |conditions. |many |produce |large |numbers |of |
seeds |which |can |spread |over |a |wide |area |and |remain |dormant |for |a |long |time.
, how |can |you |tell |a |monocot |from |a |dicot? |- |CORRECT |ANSWER✔✔-monocots |(sedges |and |
grasses) |have |one |cotyledon, |parallel |leaf |veins, |flower |parts |in |multiples |of |3 |and |fibrous |
roots. |Dicots |have |2 |cotyledons, |broad |leaves |with |netted |veination, |and |flower |parts |in |
multiples |of |4 |and |5 |and |usually |have |taproots.
name |the |pathogens |that |cause |most |plant |and |animal |diseases |- |CORRECT |ANSWER✔✔-
fungi, |bacteria, |mycoplasma, |and |viruses
what |are |the |symptoms |of |viral |plant |diseases |- |CORRECT |ANSWER✔✔-stunting, |yellow |rings |
on |leaves, |wilting, |and |mosaic |patterns
how |do |plant |parasitic |nematodes |harm |plants? |- |CORRECT |ANSWER✔✔-by |attacking |the |
roots, |stems |and |leaves. |nematode |root |feeding |interferes |with |a |plants |ability |to |take |up |
water |and |nutrients. |infected |plants |wilt |and |seem |to |be |suffering |from |a |lack |of |water |or |
nutrients.
how |do |mollusks |harm |plants? |- |CORRECT |ANSWER✔✔-by |feeding |on |foliage |and |fruit. |
mollusks |reduce |the |value |of |commercial |produce |if |they |feed |on |harvested |plants |and |fruit.
what |are |arthropods? |how |do |they |differ |from |vertebrates? |- |CORRECT |ANSWER✔✔-
arthropods |are |animals |with |segmented |bodies |and |jointed |appendages. |Arthropods |have |an |
external |skeleton |and |may |have |specialized |appendages |such |as |sucking |tubes, |chewing |
mouth |parts, |antennae, |and |pincers. |they |have |no |backbones |like |vertebrates
what |is |the |difference |between |gradual |and |complete |metamorphosis? |why |is |it |important |to |
know |the |life |cycle |stage |of |an |insect? |- |CORRECT |ANSWER✔✔-gradual |metamorphosis |
includes |3 |stages: |egg, |nymph |and |adult. |there |is |no |pupa |stage. |complete |metamorphosis |
includes |4 |stages: |egg, |larva, |pupa, |and |adult. |insects |that |develop |via |complete |
metamorphosis |change |body |form. |larvae |may |not |look |at |all |like |adults |within |the |same |
species.it |is |very |important |to |recognize |the |damaging |stage |for |best |treatment |results. |many |
insect |are |pests |in |one |stage |but |not |another. |especially |larval |form.
