Phylogenetic Relationships, Species Limits, and Host Specificity of Gall-Forming Fergusonina Flies (Diptera: Fergusoninidae) Feeding on Melaleuca (Myrtaceae)

Autor: S. J. Scheffer, R. M. Giblin-Davis, G. S. Taylor, K. A. Davies, M. Purcell, M. L. Lewis, J. Goolsby, T. D. Center

Publikováno v: Annals of the Entomological Society of America. 97:1216-1221

Phylogenetic analysis of recently described gall-forming Fergusonina Malloch flies was performed using DNA sequence data from the mitochondrial cytochrome oxidase I gene. Fifty-three flies reared from nine species of Melaleuca L. were sequenced. Spec

Sexual selection, male morphology, and the efficacy of courtship signalling in two wolf spiders (Araneae: Lycosidae)

Autor: Gail E. Stratton, George W. Uetz, S. J. Scheffer

Publikováno v: Behavioral Ecology and Sociobiology. 38:17-23

Males of the brush-legged wolf spider, Schizocosa ocreata (Araneae: Lycosidae), possess a conspicuous male secondary sexual character: dark pigmentation and tufts of bristles on the tibiae of their forelegs. We tested several hypotheses relating to t

Histological comparisons of fergusobia/fergusonina-induced galls on different myrtaceous hosts

Autor: R M, Giblin-Davis, B J, Center, K A, Davies, M F, Purcell, S J, Scheffer, G S, Taylor, J, Goolsby, T D, Center

Publikováno v: Journal of nematology. 36(3)

The putative mutualism between different host-specific Fergusobia nematodes and Fergusonina flies is manifested in a variety of gall types involving shoot or inflorescence buds, individual flower buds, stems, or young leaves in the plant family Myrta

Polymerase chain reaction-restriction fragment length polymorphism method to distinguish three mealybug groups within the Planococcus citri-P. minor species complex (Hemiptera: Coccoidea: Pseudococcidae)

Autor: A, Rung, D R, Miller, S J, Scheffer

Publikováno v: Journal of economic entomology. 102(1)

The mealybug species Planococcus citri (Risso) and Planococcus minor (Maskell) (Hemiptera: Coccoidea: Pseudococcidae) have special significance to U.S. quarantine and U.S. agriculture. Commonly intercepted at U.S. ports-of-entry, they are difficult t

Polymerase chain reaction-restriction fragment-length polymorphism method to distinguish Liriomyza huidobrensis from L. Langei (Diptera: Agromyzidae) applied to three recent leafminer invasions

Autor: S J, Scheffer, A, Wijesekara, D, Visser, R H, Hallett

Publikováno v: Journal of economic entomology. 94(5)

A molecular method is presented for differentiating the morphologically cryptic leafminers Liriomyza langei Frick and L. huidobrensis (Blanchard). This method requires polymerase chain reaction (PCR) amplification of a 1031-bp region of mitochondrial

Molecular evidence of cryptic species within the Liriomyza huidobrensis (Diptera: Agromyzidae)

Autor: S J, Scheffer

Publikováno v: Journal of economic entomology. 93(4)

Phylogenetic relationships among populations of the polyphagous pea leafminer, Liriomyza huidobrensis (Blanchard), were investigated using DNA sequence data. Maximum parsimony analysis of 941 bp of mitochondrial cytochrome oxidase I and II genes show
