Effects of Tagetes patula on Active and Inactive Stages of Root-Knot Nematodes.
Although marigold (Tagetes patula) is known to produce allelopathic compounds toxic to plant-parasitic nematodes, suppression of Meloidogyne incognita can be inconsistent. Two greenhouse experiments were conducted to test whether marigold is more effective in suppressing Meloidogyne spp. when it is active rather than dormant. Soils infested with Meloidogyne spp. were collected and conditioned i...
متن کاملChanges of digestive enzymes activity in Caspian Kutum (Rutilus frisii kutum) during larval developmental stages
The ontogenesis and specific activities of pancreatic (trypsin, chymotrypsin, amylase and lipase) and intestinal enzymes (alkaline phosphatase, aminopeptidase N) were investigated in Kutum (Rutilus frisii Kutum) from the onset of exogenous feeding (3 day after hatching, DAH) to the juvenile stage at 50 DAH. Trypsin- and chymotrypsin-specific activity showed similar patterns and increased with l...
متن کاملLarval and Post-Larval Stages of Pacific Oyster (Crassostrea gigas) Are Resistant to Elevated CO2
The average pH of surface oceans has decreased by 0.1 unit since industrialization and is expected to decrease by another 0.3-0.7 units before the year 2300 due to the absorption of anthropogenic CO2. This human-caused pH change is posing serious threats and challenges to the Pacific oyster (Crassostrea gigas), especially to their larval stages. Our knowledge of the effect of reduced pH on C. g...
متن کاملAn anthelmintic test for larval stages of sheep nematodes.
In recent years marked progress has been made in the efficacy of new anthelmintics. Many thousands of these compounds are synthesized by the pharmaceutical industries and the primary and secondary laboratory animal screens, through which they pass initially, have been carefully described and reviewed in the literature(Standen, 1963; Baker, 1963). After undergoing these tests promising compounds...
متن کاملA transcriptomic analysis of Echinococcus granulosus larval stages
Background: The cestode Echinococcus granulosus the agent of cystic echinococcosis, a zoonosis affecting humans and domestic animals worldwide is an excellent model for the study of host-parasite cross-talk that interfaces with two mammalian hosts. To develop the molecular analysis of these interactions, we carried out an EST survey of E. granulosus larval stages. We report the salient features...
