| histochemical studies on the body wall of nematodes: haemonchus contortus (rud., 1803) and xiphinema insigne loos, 1949. | histochemical studies on the body wall of haemonchus contortus (rud.) and xiphinema insigne loos have been made. in h. contortus, the cuticle is mainly proteinous in nature. the lipids and pas-postive materials are only present in cortical layers. in addition, haemoglobin and acid phosphatase are also present. the hypodermis shows the presence of glycogen, lipids, rna, acid and alkaline phosphatases. the oval dense body is composed of keratinous and collagenous proteins associated with acid muco ... | 1977 | 140550 |
| observations on a xiphinema insigne population with several males from hangzhou, china. | a population of xiphinema insigne with several males was found on the campus of zhejiang university, hangzhou, china, in november 1998 in the rhizosphere of yulan magnolia. morphometrics of nine males and 25 females of this population are given herein. no sperm were found in the genital tracts of 118 females that were examined. this agrees with all other observations reported for this species except for the synonym of x. insigne, x. neodimorphicaudatum, in which males are as common as females an ... | 2000 | 19270974 |
