Slight induction and strong inhibition of Heterodera glycines hatching by short-chain molecules released by different plant species

(reproductive).Within this process, the infective stage J2 needs to count on its lipid reserves that are limited, to guarantee its survival until it finds their host plant (Wharton, 2004). Cyst nematodes, such as H. glycines, developed a sophisticated parasite-host interaction, in which the egg hatching is dependent on the presence of hatching factors released by their host, thus synchronizing hatching and availability of food (Perry, 2002; Thapa et al., 2017). Over the past decades, some of SCN hatching

First Report of Matricidal Hatching in Bursaphelenchus xylophilus

The reproductive strategy of the pinewood nematode (PWN), Bursaphelenchus xylophilus, is sexual amphimictic and oviparous. The incidence of intrauterine egg development and hatching in plant-parasitic nematodes is not a very common phenomenon. During the process of maintaining and breeding a B. xylophilus population isolated in Spain under laboratory conditions, evidence of matricidal hatching was observed. This is the first described case of this phenomenon in this species.

Changes in neurogenesis with post-hatching age in the male Japanese quail (Cortunix japonica) brain

Most avian neurogenesis studies have previously focused on the song control system and little attention has been given to non-song birds. The objective of this study was to assess changes in neurogenesis associated with post-hatching age (3-12 weeks) in the Japanese quail brain using proliferating cell nuclear antigen (PCNA) and doublecortin (DCX) immunohistochemistry. PCNA-immunoreactive (ir) cells were observed mainly in the olfactory bulb ventricular zone, telencephalic ventricular zones and

The results provide important information on fosthiazate for further studies controlling H. glycines and field precision applications. Materials and methods Chemicals Fosthiazate (85.1%) was obtained from the Zhengbang Bio-chemical Co., Ltd. (Nanchang, China). In bioassay, five fosthiazate concentrations (2.18, 3.44, 5.45, 8.61, and 13.62 mg/l) were used in experiments

Reproduction and life history traits of a resistance breaking Globodera pallida population

with resistance derived from species such as Solanum vernei (Gpa1 and Gpa5), S. tuberosum spp. andigena (H1 and Gpa2), and S. spegazzinii (Gpa) among others (Bakker et al., 2006; Dalamu et al., 2012). These genes confer pathotype-specific resistance and they differ in their mode of action. Infestation of potato plants by G. pallida occurs soon after the hatching of second-stage juveniles (J2s), a process that is initiated by chemical stimuli present in the potato root exudate. The exudate is

Hatching and Mortality of Meloidogyne enterolobii Under the Interference of Entomopathogenic Nematodes In vitro

existing sources of resistance to other species of Meloidogyne (Brito et al., 2007; Cantu et al., 2009). Several methods are studied for the control of phytonematodes (Rosa et al., 2015; Silva et al., 2014). Studies show that entomopathogenic nematodes (EPNs) have potential for biological control of these parasites (Pérez and Lewis, 2004; Lewis and Grewal, 2005). In view of the above, the objective of the present study was to evaluate the hatching, mortality and infectivity of hatched juvenis of M

Meloidogyne enterolobii egg extraction in NaOCl versus infectivity of inoculum on cucumber

Barker, 1973). However, it was also suggested that 0.53% NaOCl caused a hatching delay and therefore, a lower infectivity (19.8%) when compared with intact egg masses (51.4%) (Vrain, 1977). Similarly, egg viability from dissolved egg masses in 1.0% NaOCl has been described as significantly lower (12%) when compared with viability from egg masses in water (58%) (Di Vito et al., 1986). Afterward, a comparison between stirring and grinding of 1.5 g of tomato and soybean roots (2.5-cm pieces) in NaOCl

Effect of an Alltech soil health product on entomopathogenic nematodes, root-knot nematodes and on the growth of tomato plants in the greenhouse

bionematicides/organic amendments that could be effective against PPN while displaying no negative impact on beneficial EPN. This research is therefore the first of its kind in this context. This study is designed to examine the effects of a proprietary soil health product blend of fermentation and plant extracts with micronutrients (ACS 5075, Alltech®, Inc., Nicholasville, KY USA), on the egg hatching and survival of the root-knot nematodes M. javanica and M. incognita, while studying its compatibility with

These trials revealed that although both VCTs suppressed M. incognita egg hatching compared to water control, only weed VCT suppressed R. reniformis egg hatching. In addition, both VCTs suppressed the mobility of second stage juveniles (J2s) of M. incognita equally compared to water control though suppression from weed VCT performed inconsistently between the trials. When root penetration of M. incognita on cucumber drenched with VCT on one side of a

For monitoring the egg development, eggs were observed on day 0 and were categorized either as differentiated (fully developed juvenile) or undifferentiated (eggs containing only cells). Undifferentiated eggs were considered those with cell division (one, two, or more cells). The experiment was terminated after three weeks. It was conducted twice and each treatment was replicated four times. Effect of eugenol on egg hatching from egg masses Mature egg masses were handpicked using

The results demonstrated that ALA exhibited a strong effect of suppression against the four nematodes tested. ALA also inhibited hatching of M. incognita and H. glycines. Results from the greenhouse experiment indicated that treatment of soil with 6.0 mM ALA significantly reduced the root-gall index (RGI) and

Sex of juveniles may be identified from the J3 stage by the presence of the cloacal primordium in male juvenile and orientation of the germinal zone of the genital primordium. A tabular key to developmental stages of B. crenati is given. The body grows during molts and within each stage. The body increases rapidly after J3 stage

Effect of fluensulfone on different functional genes of root-knot nematode Meloidogyne incognita

Exposure to this chemical exerts irreversible nematicidal effects affecting the motility, chemosensory perception, stylet thrusting, feeding, moulting, infection potential, oviposition capacity, egg hatching, behaviour, metabolism, lipid consumption, tissue integrity and survival in root-knot, cyst and other nematode species (Kearn et al., 2014, 2017

Evaluation of Pochonia chlamydosporia and Purpureocillium lilacinum for Suppression of Meloidogyne enterolobii on Tomato and Banana

Purpureocillium lilacinum strains were screened for their ability to infect eggs of the root-knot nematode M. enterolobii on water-agar surfaces. Reduction in the hatching of J2 varied from 13% to 84%, depending on strain. The more efficacious strains reduced hatchability of J2 by 57% to 84% when compared to untreated eggs, but average reductions were only 37% to 55% when the same strains were applied to egg masses. Combinations of fungal isolates (one of each species) did not increase the
