Mustard oil is known to exhibit activity against nematodes and pathogens due the presence of Ally Isothiocyanate. Since past decade, use plant-based pesticides becoming more popular a lot research being done worldwide on plant metabolites for protecting crops various biotic factors. In tomatoes, disease complex involving root-knot nematode, Meloidogyne incognita, wilt fungus, Fusarium oxysporum...

The aim of this study was to determine the accuracy and precision of McMaster method with Raynaud's modification in the detection of the eggs of the nematodes Toxocara canis (Werner, 1782) and Trichuris ovis (Abildgaard, 1795) in faeces of dogs. Four variants of McMaster method were used for counting: in one grid, two grids, the whole McMaster chamber and flotation in the tube. One hundred sixt...

Capillaria hepatica is a nematode with worldwide distribution, which can cause parasitic hepatitis both in animals and humans. A mouse (Apodemus flavicollis), trapped in Giresun Province was diagnosed as having capillariasis due to the characteristic eggs found in its liver. This is the first reported case of mouse capillariasis in this part of the country. Due to the fact that capillariasis is...

Hystrignathus dearmasi sp. n. (Oxyurida: Hystrignathidae) is described from an unidentified passalid beetle (Coleoptera: Passalidae) from Panama. It resembles Hystrignathus cobbi Travassos & Kloss, 1957 from Brazil, by having a similar form of the cephalic end, extension of cervical spines and absence of lateral alae. It differs from the latter species by having the body shorter, the oesophagus...

Physaloptera bispiculata (Nematoda: Spiruroidaea) is a parasite of Nectomys squamipes (Rodentia: Cricetidae), a water rat that only occurs in Brazil. Naturally infected rodents were captured in the municipality of Rio Bonito, Rio de Janeiro, Brazil. Adult P. bispiculata worms were collected, prepared and analysed by light and scanning electron microscopy. Under scanning electron microscopy, sev...

Meloidogyne partityla is a parasite of pecan and walnut. Our objective was to determine interactions between the entomopathogenic nematode-bacterium complex and M. partityla. Specifically, we investigated suppressive effects of Steinernema feltiae (strain SN) and S. riobrave (strain 7-12) applied as infective juveniles and in infected host insects, as well as application of S. feltiae's bacteri...

Eggs of the root-knot nematode Meloidogyne incognita were acclimated to 23 C. Newly hatched second-stage juveniles migrated toward higher temperatures when placed in shallow thermal gradients averaging 23 C. The threshold gradient for this response was below 0.001 C/cm, with a best estimate of 4 x 10 C/cm. Calculations of physical limitations on thermotaxis indicate that this sensitivity is wel...

The life cycle of Belonolaimus longicaudatus was observed in vitro on excised roots of Zea mays. Roots were cultured on Gamborg's B5 medium in petri dishes with 1.5% agar adjusted to pH 5.8 and incubated at 28 degrees C in darkness. Second-stage juveniles (J2) fed on the roots and started the second molt (M2) to the third-stage juveniles 2 days after inoculation (DAI). The third molt (M3) to th...
