Insect galls may be study models to test the distribution of pectins and arabinogalactan-proteins (AGPs) and their related functions during plant cell cycles. These molecules are herein histochemically and immunocitochemically investigated in the kidney-shaped gall induced by Baccharopelma dracunculifoliae (Psyllidae) on leaves of Baccharis dracunculifolia DC. (Asteraceae) on developmental basi...

Meloidogyne minor, first reported on potatoes in the Netherlands in 2004, is an emerging nematode pest in Europe. It damages turfgrass, particularly creeping bentgrass (Agrostis stolonifera) grown on sandy soils such as those of golf greens. However, little is known of the nematode’s life history and pathology. In this study, the spatial and temporal distribution of M. minor on a creeping bentg...

A total of 133 stones in renoureteral and bladder units from 122 patients, 8 to 80 years old, were treated by extracorporeal shock wave lithotripsy (ESWL) with the Wolf Piezolith device from November 1989 through December 1990. The 133 stones involved renal stones (91), ureter stones (34) and bladder stones (9). The number of shock waves per session was up to 4,000 shots, the mean number of sho...

INTRODUCTION Gall bladder is a pear shaped secular Organ which stores bile, is also place for formation and growth of gall stones. Today the incidence of Cholelithiasis is increasing considerably in India. The aim of our study are to know the incidence of gall stones in relation to age and sex, the relation of diet in gall stones, the clinical presentation of gall stones, the best mode of inves...

introduction: few researches have been conducted researches on the influence of the type of dental stone used for fabrication of casts on the adaptation of denture bases. the purpose of this study was to compare the effect of two types of stone casts on the accuracy of fit in complete denture bases. methods: using sixty fully replicated master casts obtained by duplicating a metal die represent...

The structure-activity relationship of 12 isolated acetylenes from galls of Hedera rhombea (Araliaceae) induced by Asphondylia sp. (Cecidomyiidae) and their derivatives has been studied for the inhibition of the shoot and root growth of rice, perennial ryegrass, cockscomb, lettuce, and cress. Almost all acetylenes generally showed growth inhibitory activity. The diacetylenes exhibited higher ac...

A field survey was carried out to investigate kenaf plants cultivated in Telaga Papan, Terengganu, Malaysia with respecting to their performance, root galling and growth characteristics. In this investigation, the aims were to assess the status of nematode infection on kenaf planted on this sandy BRIS area and estimate the incidence and severity of infection. Inspection of kenaf plants showed d...

‘On closer examination the root was found to be covered with excrescences varying from the size of a small pin’s head to that of a little Bean or Nutmeg.’ This observation, from one of the first accounts of root-knot nematodes on plants, was made by Berkeley (1855), an eminent Victorian scientist, on publishing his discovery of galls produced by nematodes on the roots of cucumbers growing in a ...

A new sCecies of Tanaost~gmodes (Hymenoptera Chaicidoidea Tariaostigmal~dae) is described from China-Tanaoshgmodes pueranae sp nov This is the first record of this fam~ly In China This new species has potent~al as a brological control agent for control of kudzu, Puerana lobate in the U S because its preference for making leaf galls on kudzu It was determined that the wasp has two generations pe...

A new genus of cynipid oak gallwasp, Zapatella Pujade-Villar & Melika, gen. n. (Hymenoptera: Cynipidae: Cynipini), with two new species, Zapatella grahami Pujade-Villar & Melika, sp. n. and Zapatella nievesaldreyi Melika & Pujade-Villar, sp. n., is described from the Neotropics. Zapatella grahami,known only from the sexual generation,induces galls in acorns of Quercus costaricensis and is curre...
