Haemonchus contortus affect small ruminants all over the world. Anthelmintics cause resistance, contamination, and a risk of public health. Prosopis laevigata is plant used as home remedy against many diseases in Mexico. This study arose from preliminary where P. hydroalcoholic extract (Pl-hae) showed anthelmintic activity (aa) H. contortus. Searching for bioactive compounds (bac) with high aa, Pl-hae was fractioned obtaining an aqueous (Aq-F) ethyl acetate fraction (EtAc-F), flavonoid aa...

Pithecellobium dulce (Robx.) Benth is an arboreal legume used in traditional medicine for the treatment of several ailments, including a number intestinal disorders, and as natural deworming. The objective this study was to evaluate ovicidal activity hydroalcoholic extract (HA-E) its fractions (aqueous, Aq-F organic, EtOAc-F) from P. leaves, well subfractions (C1F1-C17) obtained EtOAc-F against Haemonchus contortus eggs. HA-E, Aq-F, were assessed at 0.03-5.00 mg/mL 0.06-1.00 mg/mL. HA-E...
The individual and combined effects of extracellular products (ECP) from Arthrobotrys oligospora (Ao) A. musiformis (Am) growth in liquid media against Haemonchus contortus L3 (HcL3) were assessed. following methodological steps established: isolation, morphological (MI) molecular identification (Mol-I), assessment nematocidal activity (NA) fungal liq-uid culture filtrates (LCF) produced two alone combination finally, the myco-compound profile (MCP). MI both isolates suggested that fungi...
The objective of this study was to assay the ovicidal and larvicidal effects two hydroalcoholic extracts (HA-E) their aqueous fractions (Aq-F) organic (EtOAc-F) from Lippia graveolens (leaves) Delonix regia (flowers) against parasitic nematode Haemonchus contortus. egg hatching inhibition test (% EHI) mortality infective larvae mortality) were used as biological models. treatments each plant (mg/mL, % EHI, assigned follows: HA-E (12.5-50, EHI; 25-200, mortality), Aq-F (6.25-25.00, 12.5-50,...
Medicinal plants are crucial for developing new medicines; the Agastache mexicana subspecies (Amm) or “toronjil morado” is considered an at-risk plant because of its inability to grow outside natural habitat. This research aims measure response Amm achieve survival with low nutrient levels and water stress, supported by different dioxide silicon (SiO2) (0.0, 0.2, 0.4, 0.8%) artificial shading (AS) (38, 87, 94%). Applying AS SiO2 gradual tolerance effects both waterlogging drought stresses....
The sugarcane aphid, Melanaphis sorghi Theobald, 1904 (Hemiptera: Aphididae), is the most important pest of Sorghum bicolor (L.) Moench (Poaceae), in Mexico. Control M. depends primarily on synthetic chemical insecticides, but new alternatives have been explored, such as botanical insecticides. objective this research was to evaluate aphidicide effect extract nhexane and methanol from stems Ceiba aesculifolia (Malvaceae) against apterous adults vitro. results revealed that n-hexane C. killed...
The nematocidal activity of an Oxalis tetraphylla hydroalcoholic extract against the nematode Haemonchus contortus (Hc) was assessed in vitro and major compounds associated with were identified. One obtained from O. stems leaves (Ot HE-SLE). lethal concentrations (LC50 LC90) both eggs exsheathed Hc infective larvae (L3) assessed. Ot HE-SLE showed a potent ovicidal = 0.213 mg/mL; LC90 0.71 mg/mL) larvicidal effect 28.01 69.3 mg/mL). Later on, bipartitioned to obtain ethyl acetate phase...
Arthrobotrys oligospora is a nematode-trapping fungus belonging to the family Orbiliaceae and one of main antagonists nematodes in soil, including plant animal parasitic free-living nematodes. This species develops three-dimensional adhesive nets which are trapped, destroyed consumed by fungus. It also possesses other strategies immobilise, kill degrade nematodes, i.e. nematode-attractant substances, cuticle adhesion polymers number nematocidal metabolites. The objective this study was...
