what is the easiest kind of trap
pitfall trap baited with carrion
how do you build a pitfall trap
- bury a solo cup to ground level and pack soil around edges to allow beetles to fall into it
- put your carrion bair onto a cheese cloth and form it into a bag
- form there, tie ends w wire mesh large enough to cover the trap opening
- pour 5cm of preservation into the trap (propylene glycol)
- place your bag into the container suspende dby the mesh, but do NOT allow the bag to touch the side of the container or the solution
how often should you check a pitfall trap
every 3-5 days
how foten should bait be changed in a pitfall trap
- as needed
- can be weekly or up to 3 weeks
true/false you should trap various location
- true
- should trap in urban, rural, wooded, shaded, barn etc
how do you build a bottle trap (ground)
- have mesh on the ground that allows the flies to crawl in but not out
- then have a spout going into a bottle where the flies get stuck
how should you get immature nicrophorous sp
- rear them
- wait for them to bury the carrion, and then capture the male when he tried to leave
- excavating carrion after 2 weeks will allow you to get larvae
- then rear them
how should you kill adults
- put them in a killing jar with a cloth with 2 drops of ethyl acetate
- just use cheap nail polish remover
- leave them for 2 hours in jar
- then pin within 24 hours before they become brittle
what is a good way to prevent damage from mixing beetles while killing them
roll them up in paper envelopes or tubes and then put into killing jar
how should you preserve larvae
- in ethanol or rubbing alcohol in glass vials
- should be 75-80% ethanol (can use vodka, gin, or white rum even tho theyre only 40%)
- label with PENCIL (pen will run)s
should you use a pooter or aspirator around carrion
- NEVER
- you’ll suck rotting flesh into your lungs
how should you label insects when mounting
- in black, by computer or hand
- be consistent (more important that they’re the same than the actual size of them)
- onto 1/2 by 3/4 inch or 8mm by 15mm, or 12mm by 20mm
what should be put on a label
- place of capture (clear to anyone unfamiliar w region, coordinates if needed)
- date
- person who captured
what should be on an ecological label
includes habitat and life history inf that the collector identifies important (host animal/ plant, conditions of capture, rearing info etc)
why should the identification label be at the bottom
cause if you release you made a mistake on identification, you can take it off the pin without removing the ecological label and collecting data
where should you pin large insects
- thorax (flies)
- right hind wing (beetles)
where should you pin small insects
glued to the pin or to paper points using nail polish or white glue
how do you build a bottle trap (tree)
- empty a big sode bottle then cut circular holes on the side
- attach a jam jar with liver in it to the bottom of the sode bottle
- pull string through the bottom the hand the carrion bait on
- literally no clue his slide is so ass i have no idea
how do you collect immature flies
- place them in hot water
- collect maggots and then place in a strainer
- dip into hot water for a few seconds until they die
- place maggots into 70-80% ethanol
how should you collect pupae
- shortly after maggots reach 3rd instar and wandering, we know the pupae will come cause no competition
- dig daily soil samples (3-5) from near the carcass
- should be 2 inches in diamerer and 5 inches deep
- collect any pupaae
- rear in a rearing contaer
- record how long they take to emergy as asults
- preserve other pupae in 70-80% ethanol
hwo should you store amggots, pupae, and eggs
- place in glass vials
- add ethanol
- label (in pencil) with: name, place, date, identification, ecological info
describe the simplified LeGros trap
- get a big soda bottle and cut a big hole in it
- hang liver in the hole
- add a collecting bottle with propylene glycol antifreeze in it to the bottle of the soda bottle
- hang all of this on a hanger and put outside
why would we soak flies in aceton
- dissolves the fat and oil
- makes colours vibrant
