dragging/flagging

A

Large sheet used to collect insects residing close to the ground

180
Q

trapping

A

all trapping techniques require the insect ton move and the trap must hold the captured insect

181
Q

remote sensing

A

any monitoring method at documents organism presence without coming into direct contact with organism

182
Q

Subeconomic pests

A

damage usually below the EIL

183
Q

occasional pest

A

common type of pest, damage usually below EIL

184
Q

perrenial and severe pests

A

pests that cause the most serious damage

185
Q

how to develop pest management programs

A

combine well designed programs, know your pest and production system, kind of damage the pest is doing

186
Q

host (prey)

A

propulation being reduced

187
Q

goal in understanding natural enemies

A

using them to our advantage

188
Q

forms of biocontrol

A

host plant resistance, sterile insect releases, genetic manipulation, use of natural enemies

189
Q

oldest and most effective form of insect control

A

biocontrol

190
Q

What is classical biocontrol

A

populations regulated by many environmental conditions (introduce natural enemies/manipulate existing natural enemies)

191
Q

parisite

A

animal that lives on/within its host (weakens or kills host)

192
Q

parasitoid

A

insect that parasite other insects

193
Q

most common biocontrol

A

Parisitoids

194
Q

parasitoid familites

A

Hymenoptera & diptera

195
Q

parasitoid life cycle

A

lays egg inside or attaches eggs to host body
larvae develop within host body
mature larvae emerge from body of now dead host
larvae pupate and emerge as adults to mate

196
Q

parasitoid advantages

A

survival usually good, only 1 host required for parasitoid to complete development
population can be sustained at low host levels
most parasitoid have/narrow host range effective against specific hosts

197
Q

parasitoid disadvantages

A

host searcing capacity may be reduced by weather/other factors
only female searches for host
often best searchers lay few eggs
synchronization of life cycle

198
Q

how are nematodes used

A

in gels, clays, flowable gels, water dispersible granules for high and medium value crops.

199
Q

Nematodes

A

thin unsegmented roundworms. can parasite insects.

199
Q

hyperparsitism

A

secondary parisite

200
Q

can a parasitoid have its on parasite

201
Q

predator

A

free-living organisms that feed on other animals and prey

202
Q

Monophagous

A

feed almost exclusively on a single species

203
Q

oligophagous

A

feed on only a few prey species

204
Q

polyuphagous

A

feed a diverse range of prey species (most common)

205
Q

What do pathogenic microorganisms do

A

can kill insects, reduce reproductive capabilities, or slow development

206
Q

goal of biocontrol

A

Natrual enemy will become estabilshed and permanetly reduce pests average population level

207
Q

Augmetnation

A

any activity designed to increase numbers or effectivenesse of existing natural enemies. (release additoinal numbers of natural enemy into a system)

208
Q

goal of augmentation

A

temporary(1sesaon or less) suppression of insect pest population

209
Q

inudative release

A

dependant on propagation of massive numbers of natural enemies. release pf a generalized parasitoid over large areas in a 1 time application

210
Q

goal of inundative release

A

polyphagoys natural enemies suppress multiple different insect populations over a large area

211
Q

Proactive biocontrol

A

new concept. promotes proactive use of biocontrol for invasive pests. potential biocontrol for release

211
Q

inoculative releases

A

once release occurs natural enemy is expected to colonize and spreasd throughout area naturally, typically made 1 time per growing season. offspring make the most significant impact

212
Q

goal of proactive biocontrol

A

be prepared with a biocontrol agent for potential invasive species

213
Q

Environmental manipulation

A

manipulate crop or surrounding areas using field insecrataries. increase population or make existing populations more efficient

213
Q

goal of environmental manipulation

A

improve habitat and enviromental factors fro natural enemies

214
Q

Conservation of natural enemies

A

most widley practived biocontrol. requires in depth knowledge of natural enemy population (speciese present, population numbers, phenology, impact on pest populations)

215
Q

goal of conservation of natural enemies

A

sustain natural enemy populations

216
Q

What are insects?

A

3 segments, 6 legs, exoskeleton.

217
Q

why is it important to take life stags into account when sampling

A

its important to know if the insect has a long or short life cycle, and to look and see if they are sexually mature that could indicate more eggs being laid

218
Q

when do people become interested in pest management solutions

A

when they have pests

219
Q

why are there so many formulas for calculating insect damage

A

different situations. cant count by hand in a large area it would take forever
