This thesis is based on three inter-related studies: the first part deals with the microbial consortium, the identification of microbes and their volatiles, the second part deals with the study of bio-chemical control methods of two conifer pests; the pine weevil Hylobius abietis (L.) and the root rot fungi Heterobasidion spp., and the third part describes the production of styrene by a fungus ...

Meira diottii, nov.sp. from the Ligurian Alps is described. Relevant anatomical characters are detailed and illustrated with drawings and photography. Characteristic sensilla on the penis are identified and illustrated with scanning electron microscopy. Relationships with other Meira species are proposed.

Natural grain's fogging is a Indonesian traditional method which applied since many years ago. Recently, no specific research was approving this method, especially for maize. Maize weevil, Sitophilus maize L common destructive insect pest considered losses on stored grains. The aim of to determined effect grains biological S.maize L. This conducted using complete randomized design with three le...

Phenylphenalenone-type compounds accumulated in the tissues of two banana cultivars-Musa acuminata cv. "Grande Naine" (AAA) and Musa acuminata × balbisiana Colla cv. "Bluggoe" (ABB)-when these were fed on by the banana weevil (Cosmopolites sordidus (Germ.) (Coleoptera: Curculionidae)) and the banana stem weevil (Odoiporus longicollis (Oliver) (Coleoptera: Curculionidae)). The chemical constitue...

Larva and pupa of Loncophorus pustulatus (Champion, 1903) (Curculionidae: Curculioninae: Anthonomini) are described, illustrated and compared with descriptions of immatures of two other species of Loncophorus. Weevil larvae were found inside aborted flowers on the ground under Ceiba speciosa (A. St.-Hil.) Ravenna (Malvaceae), in the city of Sgo Paulo, State of S5o Paulo, and reared to adults in...

Perapion connexum (Schilsky) is recorded for the first time from Hungary and Kyrgyzstan, and new distribution data from Ukraine and Russia are provided. Preliminary placements of this weevil in faunal checklists for Poland and Slovakia are here documented with detailed data. Its occurrence in Austria based on older evidence, is discussed. The neophytic and invasive in Central Europe sorrel Rume...

l. The vitellins or yolk proteins of four species of weevil (Coleoptera: Curculionidae) consist of two size classes with molecular weights of 150-170 and 4247 kilo daltons (kDa). 2. The ho11 weevil, Anrhonomus grandis, has one large vitellin while Smicronyx fulvus, S. sordidus, and Cylindrocopturus adpersus each have two large vitellins. 3. All four weevils have a single small vitellin whose si...

Griffonia simplicifolia 11, an N-acetylglucosamine-specific legume lectin, has insecticidal activity when fed to the cowpea weevil, Callosobruchus maculatus (F.). A cDNA clone encoding G. simplicifolia II was isolated from a leaf cDNA library, sequenced, and expressed in a bacterial expression system. The recombinant protein exhibited Kacetylglucosamine-binding and insecticidal activity against...
