Several cotton genotypes with resistance to Meloidogyne incognita have been released in recent years. To estimate the durability of this resistance, galling severity on these resistant genotypes by M. incognita was measured. Nematode isolates (115 total) were collected from cotton fields in 14 Texas counties in August and September 1996 and 1997. Four additional isolates from Maryland, Mississi...
Galls are highly specialized plant tissues whose development is induced by another organism. The most complex and diverse galls are those induced on oak trees by gallwasps (Hymenoptera: Cynipidae: Cynipini), each species inducing a characteristic gall structure. Debate continues over the possible adaptive signi¢cance of gall structural traits; some protect the gall inducer from attack by natura...
In the Northeast of Brazil, expansion of guava crops has been impaired by Meloidogyne enterolobii that causes root galls, leaf fall and plant death. Considering the fact that arbuscular mycorrhizal Fungi (AMF) improve plant growth giving protection against damages by plant pathogens, this work was carried out to select AMF efficient to increase production of guava seedlings and their tolerance ...
Most effective nematicides for the control of root-knot nematodes are banned, which demands a better understanding of the plant-nematode interaction. Understanding how gene expression in the nematode-feeding sites relates to morphological features may assist a better characterization of the interaction. However, nematode-induced galls resulting from cell-proliferation and hypertrophy hinders su...
In Minas Gerais, green propolis is produced from the collection of resinous substance found in shoot apices of Baccharis dracunculifolia. The aim of this study was to evaluate the biological parameters associated with the interaction Apis mellifera x Baccharis dracunculifolia, to elucidate the supply of resin for green propolis production in Minas Gerais. We selected male and female individuals...
Herein we report results of transplant experiments that link variation in host plant quality to herbivore fitness at the local scale (among adjacent plants) with the process of local (demic) adaptation at the landscape scale to explain the observed distribution of the specialist gall former Belonocnema treatae (Hymenoptera: Cynipidae) within populations of its host plant, Quercus fusiformis. Fi...
Plant galls of Aceria granati (Canestrini et Massalongo 1894) were observed on the leaves Punica granatum (Lythraceae) in a private garden Nitra July, 2017. is monophagous gall mite damaging granatum. This was present one locality only and probably imported from Hungary via plant trade. first observation an occurrence Slovakia.
Karkatasringi, whose botanical name is Pistacia integerrima and belongs to the Anacardiaceae family, a well-known medicinal plant. This plant native India distributed along Northwest Himalayan region at about 500–2500 m above sea level. Various parts of including roots, bark galls, leaves contain number secondary metabolites. Galls are most commonly used in unconventional medicines. There vario...
