"Blinding" of shoots and a leaf gall in Amsinckia intermedia induced by Anguina Amsinckia (Steiner and Scott, 1934) (Nemata, Tylenchidae), with a note on the absence of a rachis in A. Amsinckia
Society of Nematologists, 2026Co-Authors: Nagamine C., Maggenti A. R.Abstract:"Blinding" and a leaf gall induced on Amsinckia intermedia Fisch. and Mey. by Anguina Amsinckia (Steiner and Scott) are described. A. Amsinckia induced blinding by galling the terminal apical meristem of its host. The leaf gall was formed by a ventral curling of the distal edge of the leaf. The absence of a rachis in the ovary of A. Amsinckia is noted

Morphometric Analysis of Anguina Amsinckiae from Three Host Species
Society of Nematologists, 2026Co-Authors: Pantone, Dan James, Griesbach, John A., Maggenti, Armand R.Abstract:Amsinckia species (fiddleneck) in the South Coast Ranges of California were surveyed to determine if any of the 12 different California species of Amsinckia are hosts of the nematode, Anguina Amsinckiae (Steiner and Scott, 1935) Thorne, 1961. Previously only Amsinckia intermedia Fischer and Meyer was reported as a host of Anguina Amsinckiae. The survey established that there are at least two additional hosts of Anguina Amsinckiae: Amsinckia lycopsoides Lehmann and Amsinckia gloriosa Suksdorf. Seven sites containing nematode-infected Amsinckia plants were discovered. Every site contained two or more species of Amsinckia; however, only one site contained more than one species of Amsinckia that was galled. Nematode specimens from A. intermedia, A. lycopsoides, and A. gloriosa were used in a morphometric analysis of 14 morphological variables. Stepwise discriminant analysis of the variables to separate the populations by host were successful for females, and the pairwise F-tests showed all three populations to have different group means (P < 0.05). Males from the three hosts were not always separable, however, as only the nematodes from Amsinckia gloriosa had a different group mean (P < 0.05)
