Capnodis tenebrionis (L. 1758) (Coleoptera: Buprestidae): Morphology and Behaviour of the Neonate Larvae, and Soil Humidity Effects on the Egg Eclosion
No full textCapnodis tenebrionis (L. 1758) is reported for several countries of the Mediterranean
subregion as a common phytophagous insect of many cultivated and wild species of trees and shrubs
belonging to the family Rosaceae. Infestations on stone-fruit orchards have economic effects and can
often cause the death of the plants in consequence of larval tunnelling into the roots. Egg laying occurs
in late spring and summer on the trunk base or nearby in the soil. The importance of the neonate larval
skills in relation to the biological success of this pest has stimulated its morphological, ecological and
ethological studies to better understand the hatching mechanisms and the mortality effects of humidity
on the eggs.
In the present contribution, the morphology of the fi rst larval instar is described throughout and
illustrated, and the morphological details are compared with those of the mature larva.
A survey on the hatching mode points out that neonate larvae, wherever eggs are laid, always come
into contact with the soil.
Finally, hatching rates were determined under laboratory conditions at four soil moisture levels,
expressed as percentage of the Field Water Holding Capacity. A comparison was made with respect to
a control of dry soil. The results prove that soil humidity signifi cantly affects the egg eclosion, especially
at the higher values

No full textThe peach flatheaded rootborer, Capnodis tenebrionis (L.), and its enemies
No full textCapnodis tenebrionis (L.) (Coleoptera Buprestidae) is an important and common
phytophagous insect of Mediterranean stone-fruit orchards. Current knowledge on its enemies is really
scanty and no biological control strategy has been possible to set up. The survey conducted in South
Italy areas pointed out the extreme scarcity of Capnodis natural enemies. Only a bethylid species,
Sclerodermus cereicollis Kieffer, and some entomopathogenic fungi were found. The susceptibility of
the peachborer adults to 2 commercial formulations of Bacillus thuringiensis (Berliner) was assessed
in laboratory bioassays. Both products proved to be totally inefficacious in controlling the beetles

Suture Techniques
No full textThis chapter aims to be the “appetizer” for all those who approach plastic surgery. Indeed, it is without question that surgeons must have detailed knowledge of the surgical principles, as well as surgical anatomy, of the areas in which they will be operating. This chapter includes the basics of tissue handling and surgical instruments. All the efforts that must be made to avoid microorganisms from entering the incision (asepsis) and to eliminate microorganisms if they have already entered (antisepsis), for example, sterile gowns, gloves, and masks, are illustrated. In addition, the chapter will focus on offering an overview of commonly used wound closure materials as well as wound closure techniques and special suture techniques. The primary objective of suturing is to position and secure surgical flaps to promote optimal healing. Suturing reduces postoperative pain and increases patient comfort. It reduces the chances of infection. The basic terminology and characteristics of needles and sutures, skin staples, closure tapes, and skin adhesives are presented as the selection of appropriate suturing technique and the type and diameter of the surgical needle is of paramount importance
