Cactus pear is an important source of fodder for herbivores, though its production affected by soil salinity. This work aimed to evaluate the development cactus clones subjected salt stress as a measure their salinity tolerance. The experimental design was randomized block with 6 replications. Twenty genotypes were used from Active Germplasm Bank, variability in resistance carmine cochineal [Da...

Sixteen cultivars (three resistant species and thirteen susceptible to cochineal insects) were included in the experiment evaluate their nutritional chemical compositions determine vitro digestibility of cladodes Opuntia species. Cultivars showed highly significant (p < 0.001) differences composition. The cultivars’ content ash, crude protein (CP), dry matter (DM), organic (OM), (IVDMD), (IV...

Dactylopius opuntiae ‘stricta’ lineage was released more than 20 years ago in South Africa where it has successfully controlled Opuntia stricta. However, its host preference had not been tested against all invasive cacti Africa. Therefore, the possibility exists that might control other cacti. We compared performance of on stricta, humifusa and two lineages engelmannii. Additionally, we assesse...

Abstract Background Diaspis echinocacti (Bouché) is a major pest of cactus pear species worldwide. Over the past three years, this scale insect has seen increasing interest regarding its spread and importance, as well efficacy primary parasitoids Aphytis debachi Azim, Plagiomerus diaspidis Crawford, biocontrol agents. Infestation plants by D. parasitism rates two were evaluated in fields Zemamr...

I N 1921, SCHRADER first reported the unusual cytological system in a mealy bug Pseudococcus nipae (Mask.). Further work by SCHRADER (1923a) and HUGHES-SCHRADER (1935) resulted in an exact characterization of a system of chromosome behavior which has been named “lecanoid.” These and other studies are discussed in HUGHES-SCHRADER’S ( 1948) comprehensive review of coccid cytology. One set of chro...
