SPECIES OF COCCIDIA OCCURRING IN LAMBS IN SAO-PAULO STATE, BRAZIL

The purpose of this experiment was to characterize the species of Eimeria affecting lambs and their infection pattern. Faecal samples were collected from each animal at 14-day intervals, beginning when lambs were 2 weeks old and ending when they were 32 weeks old. The oocysts were counted and identified as E. intricata, E. parva, E. pallida, E. crandallis, E. bakuensis, E. weybridgensis, E. ahsata and E. ovinoidalis. The highest oocyst counts were observed when the lambs were 4-8 weeks old.

Geographical distribution and associated environments characterisation of catuba (Trichilia catigua A. Juss. - Meliaceae) in Paraná State - Brazil

Trichilia catigua A. Juss. - Meliaceae has been traditionally used as a tonic and digestive medicine. Some Brazilian pharmaceutical firms use this species to produce phytopharmaceuticals and alcoholic beverages. The aim of this work is to determine its geographical distribution and characterise the environments where catuaba is found in the state of Paraná, in order to support the domestication strategy for the agricultural production of this species. Based on the literature, botanical collections and field observations it was established, that five species of the genus occurring in Paraná, which were identified as T casaretti, T catigua, T claussenii, T elegans, T pallida and another supposed to be T pattens. Trichilia catigua occurs within a wide but defined strip in the state. By evaluating data of climate; soil types; natural vegetation formations; mean, maximum and minimum temperatures; relative humidity; rainfall; altitudes and evapotranspiration the strip may be localised above latitude 25° in the central and Eastern regions of the state and above latitude 26° in South-western Parana. In general, T catigua was found to occur on fertile, organic-matter-rich soils and predominantly under forest canopies.

Occurrence of plant-parasitic nematodes in ornamental and flowering plants at UNESP/FCAV, campus of jaboticabal, são paulo state, brazil

The plant-parasitic nematodes are responsible for serious injuries in roots and shoots of ornamental plants, reducing its beauty and consequently its economic value. This study aimed to ascertain the occurrence and distribution of plantparasitic nematodes through the analysis of the roots of ornamental and flowering plants at UNESP FCAV's landscape. The roots were collected from fifteen different species as follows: Anthurium andreannum, Rhododendron simsii, Impatiens walleriana, Calathea stromata, Cordyline terminalis, Dieffenbachia picta, Dracaena marginata, Ficus benjamina, Spathiphyllum ortgiesii 'Sensation', Spathiphyllum wallisi 'American Beauty' and 'Mini', Odontonema strictum, Portulaca grandiflora, Strelitzia reginae, Tradescantia zebrina and Tradescantia pallida. Samples of roots were processed. The plant-parasitic nematodes identified in the samples were: Meloidogyne sp. (Anthurium andreannum, Calathea stromata, Dieffenbachia picta, Ficus benjamina, Impatiens walleriana, Odontonema strictum, Portulaca grandiflora, Spathiphyllum ortgiesii 'Sensation'), Helicotylenchus dihystera (Calathea stromata, Dracaena marginata, Portulaca grandiflora, Spathiphyllum ortgiessi 'Sensation', Tradescantia pallida, Tradescantia zebrina), Tylenchus sp. (Anthurium andreannum, Calathea stromata, Cordyline terminalis, Dieffenbachia picta, Ficus benjamina, Rhododendron simsii), Aphelenchoides sp. (Dieffenbachia picta, Spathiphyllum ortgiesii 'Sensation', S. wallisi 'American Beauty'), Rotylenchulus reniformis (Cordyline terminalis, Dracaena marginata, Odontonema strictum), Pratylenchus sp. (Spathiphyllum ortgiesii 'Sensation', Spathiphyllum wallisi 'Mini'), Ditylenchus sp. (Spathiphyllum wallisi 'Mini'), Pratylenchus brachyurus (Tradescantia zebrina). The plant-parasitic nematodes weren't found in the roots of Strelitzia reginae.

Botanical extracts: alternative control for silverleaf whitefly management in tomato

Bemisia tabaci (Hemiptera: Aleyrodidae) biotype B is one of the most limiting pests of tomato crops in the world. Tomato yield is currently dependent on the use of pesticides, which are problematic to farmers, consumers and the environment. A promising alternative to reduce the harmful effects caused by the indiscriminated use of synthetic insecticides is the use of insecticides of botanical origin. This study aimed to evaluate the effect of 3% (w/v) aqueous extracts from different structures of thirteen botanical species on the behavior of B. tabaci biotype B adults, as well as insecticidal activity of such aqueous extracts on B. tabaci eggs, nymphs, and adults infesting tomato plants. A distilled water solution was used as a negative control, and thiamethoxam insecticide (18 g/100 L of water) as a positive control. Leaf extract of Toona ciliata was observed to have the most efficient inhibitory effect in tests of extracts on whitefly behavior. Furthermore, the use of leaf extract of Toona ciliata led to the most drastic reduction in the number of adults and eggs on tomato leaflets. Leaf extract of Piper aduncum led to the greatest observed ovicidal effect (78.00% of non-hatched nymphs); however it was not effective against nymphs and adults. The leaf extracts of Trichilia pallida, Trichilia casaretti, and Toona ciliata showed the highest control indexes (67.9, 60.3, and 55.1%, respectively). For adults mortality, T. pallida was the most effective (72.8%). Our results indicate that application of extracts of T. pallida, T. ciliata, and T. casaretti are promising strategies to manage B. tabaci biotype B on tomato.
