Cockroaches

Beitragvon Brian » Do Jul 01, 2004 19:28

Hello,

My girlfriend and I are lucky enough to be coming to Mauritius for our Honeymoon in Sept.
I heard that you've got super-size roaches over there. Is it true? If so just how scary are they?
It doesn't bother me, I'm worried how my girlfriend will react! :he()
Thanks, Brian.

hi brian, now you have a problem :lol: but if this is your only one, i count you to the lucky chaps.

there are roaches in mauritius, everywhere, also in the 5 * hotels but they are very rare (if it is clean).. the size is ...hmm... like the little finger of beckham...so not that big...ordinary size...

if you worry about how your girl friend will react, always go first in a dark room. put on the light, make some nois and then you are on the save side. never use a public toilet ! :-)

if you see one...kill it quickly...they run and fly fast :lol:


best regards,

i like to add, that it is NOT a sign of clean or not.
Cockroaches can fly and that's why you can find them nearly everywhere.
but after a time, you will get use to them :lol:
*joking*
they are the "normal" size, not to small and not to big.

it is not the Madagascar hissing cockroach:

The Madagascar hissing cockroach is a large, wingless cockroach from Madagascar, an island off the coast of Africa. Little is known about its ecology, but this insect probably lives on the forest floor in rotten logs and feeds on fallen fruit. The Madagascar hissing cockroach is a fascinating insect because of its unusual ability to produce sound. However, its unusual appearance and elaborate behavior also contribute to its appeal.

The life cycle of the Madagascar hissing cockroach is long and differs some from most other cockroaches. Females are ovoviparous, that is, they give birth to live young. The female carries the egg and neonate nymphs for approximately 60 days until they emerge as first instar nymphs. One female can produce as many as 30-60 nymphs. This insect has an incomplete life cycle: egg, nymphs and adult stage. The nymphs undergo 6 molts before reaching maturity in 7 months. The nymphs and adults are wingless and can live for 2 to 5 years.

There are striking differences between the sexes. Males possess large horns on the pronutum (behind the head), while females have only small 'bumps'. The presence or absence of the pronotal horns allows easy identification of the sexes. The antennae of males are hairy while the antennae of females are relatively smooth. Finally, the behavior of males and females also differ: only males are aggressive.

The aggressive encounters between males are quite impressive. Males ram into each other with their horns and/or they push each other with their abdomens. Larger males usually win. Hissing plays an important role during male-male inter- actions. Winners of encounters hiss more than losers. The hisses of males also contain information about the size of the male hissing and may be used to assess the opponent's size. Males can also discriminate among the hisses of familiar males and strangers. These hisses are audible and can be heard by observers. Although this species is primarily nocturnal, you can see males fighting during the day.

Males also hiss during courtship interactions with females. Again, their behavior is unusual for insects in that strength and sound are used. Mating occurs in an end-to-end position. To achieve this, the male pushes his abdomen under and along the female's body until he engages the end of her abdomen.

Although hissing plays an important role in colony hierachy and courtship interactions, it is the disturbance hisses that most people are familiar with. Adult males, adult females, and older nymphs hiss when disturbed or handled. This hiss is very loud and easily heard. This is the only type of hiss produced by females and nymphs.

While many insects use sound, the Madagascar hissing cockroach has a unique way of producing its hisses. In this insect, sound is produced by forcibly expelling air through a pair of modified abdominal spiracles. Spiracles are breathing pores which are part of the respiratory system of insects. Because the spiracles are involved in respiration, this method of sound production is more typical of the respiratory sound made by the vertebrates. In contrast, most other insects produce sound by rubbing body parts (e.g. crickets) or vibrating a membrane (e.g. cicadas).

The Madagascar hissing cockroach, is an interesting insect because of its appearance, behavior, and mode of communication. This cockroach is easily maintained and reared which makes it an ideal organism to study in the classroom.

all the best to you and your new wife :ploppop

Cockies

Beitragvon MmeTortue » Fr Jul 02, 2004 9:58

Hello friends of entomology!

Here's a female opinion regarding the Mauritian cockroach: Stephan is right, it is a flying insect and loves to move around in particular in summertime (so no worries in September); however I feel cleanliness does play a big part in its appearance.

As I'm one of these famous 'German housewives' :lol: you will not find any open food in my kitchen or somewhere else in the house. Food is either in closed lid plastic boxes or in the fridge. Any cocky daring to enter our house is subject to immediate and sudden death (I got really fast since living here - even my husband is scared of me!) or in case I don't get it will painfully starve.

I guess there are some hundred percents more cockies i.e. in New York City than in Mauritius, and as far as I can tell, the NYC species is bigger than the Mauritian one.

Your girlfriend doesn't need to be scared, in particular as you will be staying in a hotel. Have a wonderful holiday on this beautiful island!!!

@Olivier: now how come you know the size of Becks finger? And is this the only part of his body you're familiar with? :PPP) :PPP) :PPP)

Actually, only the males can fly, so you have even less to worry :)

Hellp Filip,

How come you found that old posting? I had to laugh about my very own posting back then but can confirm that my opinion on the subject hasn't changed a bit.

Thanks for the information regarding the flying abilities of the male or female cockies. Next time before killing the beast I'll make a test!

Best wishes,

Mme. Tortue

Hello guys,

I've been busy with uni and all....but I'm back stronger...worry not...with:

%%%UD's GUIDE TO MAURITIAN COCKROACHES%%%

Cockroaches are one of the most commonly noted household pest insects in Mauritius as well as lizards and flies. They feed on human and pet food and damage and can leave an offensive odor. There are different types of them around the world but believe it or not, the type that we most commonly have in Mauritius is the American cockroach (Periplaneta americana) and others of the same Periplaneta species. It is believed to have originated from Africa....but I don't know why the Americans named it so.

These little buggers may enter houses via sewer connections, under doors, around plumbing, air ducts, or other openings in the foundation and like you say they may even be found in some hotels as these pesty creatures can fly at 5.4km/h :))))))). This is why it is essential that we keep food unexposed at night e.t.c.
I like crushing them.....but that annoying fluid that churns out is disgusting and smelly!



Your girlfriend might be really unlucky if you come across one as hotels have very strict cleanliness measures to abide to!


FYI, some of them still make it to my house in Mauritius as well as a few lizards!!!!


Enjoy ure stay

Best Regards
