Intensive vegetable production areas were surveyed in the provinces of Almería (35 sites) and Barcelona (22 sites), Spain, to determine the incidence and identity of Meloidogyne spp. and of fungal parasites of nematode eggs. Two species of Meloidogyne were found in Almería-M. javanica (63% of the samples) and M. incognita (31%). Three species were found in Barcelona, including M. incognita (50%...

Guardian peach rootstock was evaluated for susceptibility to Meloidogyne incognita race 3 (Georgia-peach isolate) and M. javanica in the greenhouse. Both commercial Guardian seed sources produced plants that were poor hosts of M. incognita and M. javanica. Reproduction as measured by number of egg masses and eggs per plant, eggs per egg mass, and eggs per gram of root were a better measure of h...

The relationship between the initial (Pi) and final (Pf) population densities of Meloidogyne javanica in response to increasing initial inoculum levels and the effect on yield in zucchini cv. Amalthee (Cucurbita pepo L.) was determined using a geometric series of 12 Pi from 0 to 51,200 eggs/100 cm of soil in pot experiments in a greenhouse. The maximum multiplication rate was 425, and the equil...

To carry out this study, total DNA was extracted from eggs and from second stage juveniles of several populations of Meloidogyne javanica and Meloidogyne incognita, using phenol / chloroform method. Following extraction, DNA was electrophoresed on 1% agarose gel to determine its quality and quantity. A specific primer pair (C2F3 / 1108 23 and 20 nucleotides, respectively) was used to discrimina...

Potato is a strategic crop in Tunisia but is susceptible to many pests and diseases. Nematodes of the genera Meloidogyne and Globodera are important pests that cause yield losses and depreciation of tuber quality. A trial was carried out in a plot where the soil was naturally infested with M. javanica and G. pallida. Three soil treatments were tested and compared. Soil solarization (SS) and inc...

The Malayan pangolin (Manis javanica) is an unusual, scale-covered, toothless mammal that specializes in myrmecophagy. Due to their threatened status and continuing decline in the wild, concerted efforts have been made to conserve and rescue this species in captivity in China. Maintaining this species in captivity is a significant challenge, partly because little is known of the molecular mecha...

Pueraria javanica (P. javanica) is a type of Leguminosae with vine growth well-fixation nitrogen, so that can be used as ground cover plant and forage food riched in protein (15-25%). In addition, the beneficial ability symbiosis arbuscular mycorrhizal fungi (AMF) has caused this to utilized host for testing effectiveness different dosage forms AMF on P. which was carried out Bukit Harapan sub-...
