Plant Growth Hormones in Pinyon Insect Galls
BYERS J. A., BREWER J. W. & DENNA D. W. 1976. Plant growth hormones in pinyon insect galls. Marcellio 39, 125-134. Larvae of the midge Janetiella sp. near J. coloradensis Felt (Diptera: Cecidomyiidae) cause galls at the base of young needles of pinyon Pinus edulis Engelm. Bioassays of extracts from these galls contained as much as 17 times more auxin activity and as much as 21 times more gibber...
متن کاملNematodes from galls on Myrtaceae. VIII. Fergusobia from small galls on shoot buds, with descriptions of four new species.
Small shoot bud galls induced by the Fergusobia (Nematoda: Neotylenchidae)/Fergusonina (Diptera: Fergusoninidae) mutualism occur on various Eucalyptus spp. Four new species of Fergusobia, collected from small shoot bud galls on Eucalyptus camaldulensis, E. gomphocephala and E. leucoxylon, are described. Fergusobia gomphocephalae Davies n. sp. is morphologically characterized by a combination of...
متن کاملInsect galls of Restinga de Marambaia (Barra de Guaratiba, Rio de Janeiro, RJ).
Thirty-one morphotypes of insect galls and two flower damages were found on 16 families, 22 genera and 24 plant species in Restinga de Marambaia (Barra de Guaratiba, Rio de Janeiro, RJ). Fabaceae and Myrtaceae were the plant families with the greatest richness of insect galls (4 and 6 morphotypes, respectively), and the greatest number of galled plants (four and three species, respectively). Ga...
متن کاملCould the Extended Phenotype Extend to the Cellular and Subcellular Levels in Insect-Induced Galls?
Neo-ontogenesis of plant galls involves redifferentiation of host plant tissues to express new phenotypes, when new cell properties are established via structural-functional remodeling. Herein, Psidium cattleianum leaves and Nothotrioza cattleiani galls are analyzed by developmental anatomy, cytometry and immunocytochemistry of cell walls. We address hypothesis-driven questions concerning the o...
متن کاملTerminal-instar larval systematics and biology of west European species of Ormyridae associated with insect galls (Hymenoptera, Chalcidoidea)
A systematic study of the genus Ormyrus (Chalcidoidea, Ormyridae) was conducted based on the morphology and biology of the terminal-instar larvae of ten west European species that are parasitoids of gall wasps and gallflies of the families Cynipidae, Eurytomidae and Tephritidae. The first detailed descriptions are provided of the terminal-instar larvae of these ten species using SEM images to i...
