I want to do a science fair

[ABbuggin]

Well since I'm in my last year of highschool I want to do a science fair. I did one when I was 12 or so about mantid behavior when in the presence of others and won the fair (my subjects were chinese mantid nymphs). I want to participate again, but I want it to be about mantids like before. Any suggestions?

Thanks!

Why not debunk the common misinformation about laws and mating rituals of the mantid, to start.

I was thinking of a more long term project, like over a mantid's span from ooth to adult. I have G. gongylodes ooths due to hatch in 1-2 weeks so they should be perfect subjects (depending on the project of course). B)

The fair isn't until December/January so I have about 5-6 months. I would love to start as soon as possible though.

Well, take lots of pictures and take daily notes on any changes, temp. humidity, feeding, hatch rate, gender ratio(when known) mortality rate, general info on the species. Then figure out something with the data you've collected.

That's true, but I would like to make a hypothesis, collect data and either prove or disprove it when done with the experiment. That's what I did with my last one, and I liked that approach.

maybe you could design an experiment to tell whether mantids will eat fruit( I read it in a book once and i don't believe it. It said that mantids will eat fruit when theres nothing else to eat.)

Does the idea of researching prey recognition interest you?

 

[ABbuggin]

Darthmantis......Thanks for the suggestion, but I'm wanting to do something more in depth/intriguing.

O.K. Prey recognition is pretty much "in depth" and not a lot, so far as I know, has been done on a mantis's ability to distinguish one kind of prey from another,and demonstrate a preference based on past experience, but tell us what you consider "intriguing," and let's go from there! Remember, if you use gongies exclusively, your research will tend to be about them, not mantids in general.

Hmmmm, interesting idea.

I was talking to darthmantis in my last reply.

I was thinking of using the gongys to perform the experiments, but I would focus on "can a mantis.......", not "does the G. gongylodes......". Not sure if I said that very clearly, but do you understand what I trying to say?

LOL! Do you have Prete's book (don't worry if you don't, that prob is easily solved)? There are several chapters in there on the neurology of prey recognition using black targets of various sizes and shapes, etc.

Because of your substantaial knowledge in raising a variety of insects, you could perform a series of experiments that would demonstrate or refute a hypothesis that mantids, though they will eat most moving prey of the right size, might come to show a "preference" for one kind or another, based either on experience or "hard wiring." You could raise different mantids on different foods (maybe three or four types) time the time from introduction to capture of the prey, wait until you get an optimal (shortest) reponse and then swap foods for the different groups and see if there is a different response time (you'd need a stop watch and lots of time, of course!). A variation of the same experiment would be to introduce the type of prey to which a particular mantis is accustomed and one of a type that it doesn't know and see if there is a consistent pattern of taking the former first. The question of recognition of toxic insects, and I can only think of the milkweed bug right off, might also be interesting. I'm sure that you've read about Batesian mimicry.

Wadjathink?

How about proving/disproving the outcomes of different environments (heat/humidity/size/feeding schedules).

 

[ABbuggin]

Phil--

I do have Prete's book, I actually got it for Christmas last year. I have been reading it (while trying to understand certain parts at the same time LOL) but its VERY in depth. I like you suggestion of prey recognition a lot. I like the idea of comparing whether a mantis likes a certain type of insect more than another, and whether it can tell which are poisonous/venomous. Of course, just as you mentioned before, this type of experiment would be best performed on more than one species...preferably 3-4. Do you think this kind of experiment be best performed once mantids can eat things other than fruitflies? Young nymphs can't eat much other than ff's...... Do you think this is a good idea?

That's a good idea, but doing an experiment like that would result in a loss of many mantids. I'm not sure if I feel like loosing my gongys! :blink:

 

[PhilinYuma]

Yeah. I haven't checked Ebay lately, but we're just about at the end of the Chinese and European ooth season. Do you think that you could still get an ooth or two? RThe reason that I mention it is that they are expendable ond the gongies are not. You can legitimately extrapolate (I can go over that with you later) but several species, especially very agressive ones like the Chinese, would strengthen your findings. Perhaps you could talk with paul or one of the Beckies. Hey! You're going to win this Science Fair!

Edit: If you come up with a really good hypothesis, it might even be possible to find you a Real Live Entomologist to check out yr idea!

 

[Katnapper]

Hey AB... if you want a T. sinensis ooth for expendible mantids for whatever study you decide on, let me know... like soon, lol. I think I only have a couple left. The rest of what I'd had have been hatching left and right (several outside of enclosures in the bug room, lol). I've been kicking them out outside in the bushes around my house. I also threw 3 ooths into the bushes last week, just to empty 3 net cages for other things. But they're about at the end. (thankfully, in a way, lol!!).

Best of luck to you on your Science Fair project. I don't have any ideas for you right now. If I think of any, I'll let you know.

Phil---Good idea about using chinese since they are expendable. But I dont don't see how this experiment could be a "mantis killer". (an experiment concerning the effects of change in humidity and temp could be) Only problem with using them is I will need more room that I dont have. All my insects and animals (aside from the caterpillars, they are outside) by law of the parents have to be in my room. I also share my room with my brother so space isn't of an abundance...... I will find a place for them though. :lol: I do work at a museum alongside with the lead entomologist, so I will also be able to ask for ideas/suggestions etc. I'm entertaining the idea of doing a comparison of chinese vs. gongylus concerning prey recognition. One species likes what ever it sees, and the other seems to prefer flying insects. I should have an abundance of gongys, at least 30-50. Since they can be kept together, this saves a lot of precious room.

How many mantids do you think would be enough for test subjects? I was thinking 10 of each species, 5 male and 5 female. Not only could I compare species, but I could compare genders. I don't personally think that there will be much of a difference among different genders, but you never know. I would of course keep extras on hand (don't plan on selling many gongys ATM anyways) in case one mis-shed or something....chinese are pretty good at this lol.

Kat---Thanks for you offer, a chinese ooth would be great. You can just send it with the other mantids and I'll make sure to send a little something extra on my end.
