hemiptera

[nuggsy]

anyone any ideas what the most common one to forestry or arb might be ?

once again this is for the project im doing atm but searching hemiptera is like trying to find hens teeth lol

Suckers mate.

 

The greatest impact on trees is probably aphids - so i'd start there. You might have different angles to look at if you broke it down into forestry, nursery, fruit cultivation and amenity inpacts...

Hemiptera= leafhoppers, aphids and in fact round 8000 different kinds of "bug" sorry cant be more help, not a strong point of mine.

doesnt seem to be the internets strong point eather andy lol, ive searched n searched n better searched but still cant find the most common.

mite put down aphids lol can find them no probs

Speaking of Hen's Teeth - the so called Talpid mutation can cause the domestic chicken (Gallus gallus domesticus) to grow the teeth that its evolution suppressed...

capsid bugs, leaf hopper with so many species there must be something out there. http://www.rhs.org.uk/advice/profiles0600/capsid_bug.asp

also scale insects come under this category so: http://en.wikipedia.org/wiki/Icerya_purchasi

I thought I had an answer for you , luckily I checked my facts and I was wrong:thumbdown:

 

In forestry one of your worst enemies in the "bug" world is the pine weevil [Hylobius abietis ] which is in the order Coleoptera

not Hemiptera so all I can do is put you on to good old Wikipedia

 

 

God bless Wikipedia:thumbup:

 

Hemiptera is an order of insects, comprising around 80,000[2] species of cicadas, aphids, planthoppers, leafhoppers, shield bugs, and others. They range in size from 1 mm to around 15 cm, and share a common arrangement of sucking mouthparts [3].The defining feature of hemipterans is their possession of mouthparts where the mandibles and maxillae have evolved into a proboscis, sheathed within a modified labium to form a "beak" or "rostrum" which is capable of piercing tissues (usually plant tissues) and sucking out the liquids — typically sap.

 

The name "Hemiptera" is from the Greek hemi ("half") and pteron ("wing"), referring to the forewings of many hemipterans which are hardened near the base, but membranous at the ends. These wings are termed hemelytra (singular: hemelytron), by analogy with the completely hardened elytra of beetles. They may be held "roofwise" over the body, or held flat on the back, with the ends overlapping. The hindwings are entirely membranous and are usually shorter than the forewings.

 

The wings of Hemiptera are either entirely membranous such as in the Sternorrhyncha and Auchenorrhyncha or in the form of hemelytra in the Heteroptera, the true bugs. Hemelytra refers to the partially hardened forewings, usually the anterior portion or the corium. The hindwings of Heteroptera are membranous.

 

The antennae in Hemiptera are typically five-segmented, although they can still be quite long, and the tarsi of the legs are three-segmented or shorter [4].

 

Although hemipterans vary widely in their overall form, their mouthparts (formed into a "rostrum") are quite distinctive; the only orders with mouthparts modified in a similar manner are the Thysanoptera and some Phthiraptera, and these are generally easy to recognize as non-hemipteran for other reasons. Aside from the mouthparts, various insects can be confused with hemipterans, including cockroaches and psocids, both of which have longer many-segmented antennae, and some beetles, but these have fully-hardened forewings which do not overlap [5].

 

 

 

 

I wish I had paid more attention in Forest Science, I have a few books on forest pest/insects , if I find out more , I'll post it here for you

thanks for the help folks, il get there eventually lol
