The aim of this work is to study the oregano essential oil (OEO) composition from Northwestern Argentinean regions and evaluate its effect on lactic starter cultures. used, Origanum vulgare var hirtum, was obtained Andalgalá, Catamarca. presented high amounts α-terpinene (10%), γ-terpinene (15.1%), terpinen-4-ol (15.5%) thymol (13.0%) as main components. No negative growth or metabolic activity acid bacteria Streptococcus thermophilus CRL 728 813, Lactobacillus delbrueckii subsp. bulgaricus...
Abstract The corn leafhopper Dalbulus maidis (Hemiptera: Cicadellidae), a specialist herbivore, is the cause of serious losses in maize yield for its capacity to transmit three important plant pathogens. They are also active phloem feeders, that insert stylets into as they feed. Females place their eggs endophytically, totally inserted central midrib or leaf blades, leaving conspicuous openings where ovipositor was inserted. In spite consequences feeding and oviposition may have on water...
Abstract Ceratitis capitata (Diptera: Tephritidae) is a highly polyphagous species and seriously pest with significant economic importance, having great number of studies focused in its management. Recently, there has been surge interest the symbiotic relationship between gut bacteria their insect hosts. In this context, objective work was to evaluate role microbiota on aposymbiotic wild medfly adult sexual behaviour, especially mate choice mating success. We also latency time, sperm...
Abstract After an insect herbivore has reached its host plant, contact cues from the leaf surface often determine acceptance. We studied during oviposition behavior of a willow pest, sawfly Nematus oligospilus (Hymenoptera: Tenthredinidae), specialist feeder on Salix (Salicaceae) trees, and how it determines preference in lab field conditions. described sequence behaviors that lead to egg laying most least preferred species. Then we morphology chemosensory structures present female antenna,...
Volatile organic compounds (VOCs) released by plants are generally involved in host recognition and selection for many phytophagous insects. However, leafhoppers planthoppers, is mainly thought to involve a phototactic response, but it not clear if plant could be selected based on the volatile cues emits. In this study we evaluated olfactory responses dual choice tests of two Hemiptera species, Dalbulus maidis (De Long) (Cicadellidae) Peregrinus (Ashmead) (Delphacidae), vectors...
Two new acyclic diterpenoids, smaditerpenic acid E (1a) and F (2a), along with nineteen melampolide-type sesquiterpene lactones, six of them not previously reported in yacon, were isolated from the methylene chloride leaf rinse extract. Their structures elucidated 1D 2D NMR experiments gas chromatography coupled to mass spectrometry.
The willow sawfly, Nematus oligospilus (Förster), is a pest in Salix commercial forests and has been reported worldwide. Female adults must recognize suitable host plant to oviposit, since her offspring lack the ability move another host. We evaluated effect of conspecific herbivory on oviposition choices N. females by providing damaged (DP) undamaged (UP) plants humboldtiana, native from South America, as substrates. Local systemic effects were studied. For local treatment, twig DP with...
Summary: Mycorrhizal associations in Smallanthus sonchifolius (Poepp. & Endl.) H. Robinson (Asteraceae), Yacon, an ancient Andean crop and macroscyphus (Baker ex Martius)A. Grau, wild yacon, a close relative are described for the first time. Yacon fibrous roots growing under field conditions have high levels of colonization by arbuscular mycorrhizal fungi (86 %). Other colonizing included dark septate endophytes (45 %) unidentified that probably saprophytic (25 were observed. Only 9%...
