Alternativas para o controle de nematoides gastrintestinais de pequenos ruminantes

Sheep and goat farming requires an efficient management program, due to losses caused by parasites in susceptible animals. Many factors may collaborate to improve infection tolerance in the herd, such as: genetics, nutrition, physiological status, and age. The problem caused by resistance to antihelmintic agents has led to the spread of alternative techniques for parasite controls. The latest strategies include selective treatment with the FAMACHA method, phytotherapy, biological control with predatory fungi, and strategies that still await scientific confirmation, such as homeopathy, the dilution of resistance with the introduction of susceptible parasites, and the combination of drugs without antihelmintic effect. The main objective of these methods is to reduce the usage of antiparasitic agents, thus slowing the development of resistance and promoting the better use of effective products and newly released products. The objective of this article is to describe techniques for controlling nematodes in small ruminants, and it is aimed at technicians interested in increasing their knowledge about the mechanisms of resistance to antihelmintic agents as well as alternatives to the use of these products.

Fungos e nematoides associados a sementes de forrageiras tropicais

This study aimed to assess the incidence of fungi and nematodes in Brachiaria sp. and Panicum maximum seeds produced in the Brazilian states of Mato Grosso do Sul (MS), Mato Grosso (MT), Goiás (GO), Minas Gerais (MG) and São Paulo (SP). The main fungi found in the seeds were Bipolaris sp., Curvularia sp. and Phoma sp.. The lowest incidence of these fungi was found for seeds of Brachiaria brizantha cultivars BRS Piatã and Xaraés, and Brachiaria decumbens cv. Basilisk, from the states of GO, MG and MS, respectively. The cultivars Marandu and BRS Piatã, from several regions, exhibited high occurrence of Aphelenchoides sp. and Ditylenchus sp.. Seeds of B. humidicola cultivar Humidicola, produced in MS and SP, did not show association with nematodes. The seeds of Panicum maximum cv. Massai and cv. Mombaça showed higher incidence of Bipolaris sp., Cladosporium sp., Curvularia sp., Fusarium sp. and Phoma sp., as well as Aphelenchoides sp. and Ditylenchus sp., especially for seeds produced in MT. Some of the detected pathogens are causative agents of diseases of major importance in forage plants, such as Bipolaris sp., causing leaf spot in Panicum, of high severity in Tanzânia, which provides serious compromising of the pasture sustainability.

Reação de crisântemos a Meloidogyne incognita, Meloidogyne javanica e Meloidogyne enterolobii

This study aimed to evaluate the resistance of 14 chrysanthemum varieties to the nematodes Meloidogyne incognita, M. javanica and M. enterolobii. The experiment was conducted in a completely randomized design, consisting of 15 treatments and 4 replicates per nematode species. Each plot was constituted of one plant per pot; plants were kept in a greenhouse and inoculated with 5,000 eggs and possible juveniles of M. incognita, M. javanica and M. enterolobii. After 60 days, the rates of egg masses, the number of nematodes per gram of root and the reproduction factor were evaluated. The varieties showed immunity to M. incognita, M. javanica and M. enterolobii, except 'Capello Vermelho' and 'White Reagon', which were susceptible and resistant, respectively, to M. incognita.
