Eucalyptus snout beetle (Coleoptera, Curculionidae)

Here we have a weevil with a tiny spider having some fun on it. I will talk about the one on the bottom :-D

I have already said that where I live our atlantic forest have been replaced by pine and eucalypsus forestal explotations.
BUT... when we play with nature and introduce a foreign forest in a different enviroment not only the trees are the strangers.

WHAT IS THIS?
The Eucalyptus snout beetle (Gonipterus scutellatus Gyll.) is a weevil native to south-east Australia, where it is a rare insect that feeds exclusively on Eucalyptus, although attacks on apple trees have been reported. It remained largely ignored until it was found in South Africa in 1916, where populations reached pest status in a few years. Damage to the Eucalyptus plantations was so extreme that in 1926 the South African Government decided to send F. G. C. Tooke to Australia, to search for natural enemies of the pest.

HOW WE FIGHT AGAINST IT?
In only 10 days, he found the mymarid Anaphes nitens, a parasitoid of Gonipterus eggs. This led to the introduction of A. nitens into South Africa and the start of one of the most impressive examples of biological control ever reported.
The egg parasitoid Anaphes nitens has been introduced into many countries as a biological control agent. Even if control has been successful in most countries no detailed study of the interactions between both species has been published.

WHERE I LIVE:
2 Gonipterus scutellatus was detected in 1991 in north-west Spain and A. nitens was introduced in early 1994. Here we report on the results of a 2-year study of parasitism in 16 localities in North-west Spain. In 1996, parasitism was so intense (80�100% of eggs) that G. scutellatus became locally extinct, and as a consequence A. nitens disappeared. In 1997, G. scutellatus recolonized the area and was followed by its parasitoid, but parasitism was low in spring, probably because the parasitoid population needed 3 weeks to achieve a similar size as in 1996.
Consequently, damage to the trees was extreme in 1997. We interpret these results as population fluctuations due to parasitoid & host interactions and suggest that parasitoids should not to be so effective as to locally extinguish their host to be useful for biological control.

We introduce the tree, a polizon pest of it, the we introduce a strange kind of wasp to fight against the pest, I am thinking about what the wasp can do with our original insects...

I found this info HERE.

Hope you like!

Your note is very interesting Felipe. Still a lot to learn about nature! Your shot looks like a science fiction game where the player has to manage two critters at once. The atmosphere you create here with a very clever light placement is strange. Very unusual and efficient presentation. I like it!

Strange world. Surprising image, Felipe. While the Americans launch rockets towards one meteorite, a tiny spider walks on a bug.
I think that the walk of the spider is more important than the journey of the rockets.

There is something else on the bug, those litle blacks spots? What are they? Parasitoid?

A more than excellent post: picture and a very instructive note.
Thanks

Wonderful photo of a free ride to accompany your note of parisitism. The lighting is great as it brinds out the rich browns and greens in this scene. Well done.

Muy buenas Felipe
La verdad es que esta foto la acabo de ver ya que estaba en la portada del TN, pero me gusta por tres motivos.
1.- El t�tulo no es de una canci�n de los chicos de Liverpool.
2.- Debido a que es un escarabajo que ataca a los eucaliptos..... me acuerdo cuando llegaron las primeras phoracantas punctatas... no se si se escribe as� y atacaron alos eucaliptales del sur..... todos los que eramos sensibles con el medio ambiente nos alegramos de que por fin alg�n bichejo atacar� a estos arbolitos tan majos..... para los intereses de quienes sacan dividendos y tan "majos" para el medio ambiente....
3.- Por el momento que pillaste al taxista, y por el fondo y por el comentario que aunque mi ingl�s no es del "todo" perfecto ;o) pero si que me parece acertado por lo que comentas y entiendo...

Un saludo.

P.D. No me lleg� nada sobre tu comentario del objetivo, tuvimos unos d�as problemillas con el servidor de correo
