George Poinar spent most of his professional life at the University of California, Berkeley, where he conducted research on insects,nematodes,biological control and amber fossils. He received a broad undergraduate education at Cornell University, where as an undergraduate, he initially studied ornithology with Peter Paul Kellogg in the Department of Wildlife conservation. However, the brilliant lectures of Loren Petry guided him into Botany, which led to a summer job testing wild plants as hosts of the leafhopper-transmitted aster yellows virus. This in turn led to a graduate assistantship in Entomology. Discovering a nematode parasite in the newly introduced alfalfa weevil that was devastating pastures through the eastern states led to specialization in Nematology and Parasitology. After graduating from Cornell he spent a year at the Rothamsted experimental station in England studying Nematology with Basal Goodey and other members of the department. Later, he continued studying study nematodes with wim Oosterbrink in Wageningen, Alain Chabaud in Paris and I. A. Rubstov in St. Petersburg. He joined the insect Pathology group at UC Berkeley as director of the insect Disease Diagnostic Service. He concentrated on nematode parasites of both agricultural crops and medically important insects, serving as a consultant for the Food and Agriculture Department and the World health organization. His research projects took him to Western Samoa, New Guinea, Australia, Malaysia, Phillipines,Thailand and Africa. In the latter continent, he described nematode parasites from blackfly vectors transmitting onchocerciasis, mosquito malaria vectors of malaria and Tse Tse flies carrying trypanosomiasis. Knowledge gained from these studies provided the background for recognizing pathogens in amber entombed vectors entombed. After Retiring from Berkeley, George moved to Corvallis Oregon where he now works out of the Zoology Department.

Brachycamacina, a new subtribe of the tribe Naupactini (Coleoptera: Curculionidae Entiminae) in Dominican amber
Plain Language Abstract
Broad- nose weevils, which include some important pests today, have a sparse fossil record, especially from the Neotropics. Discovering a new subtribe of these weevils in Dominican amber was therefore quite exciting. We have no knowledge of the biology of the fossil, other than it visited the Algaroba tree, which is the tree source of Dominican amber.
Resumen en Español
Brachycamacina, una nueva subtribu de la tribu Naupactini (Coleoptera: Curculionidae Entiminae) en ámbar dominicano
Se describe una nueva subtribu (Brachycamacina n. subtr.), un nuevo género y una nueva especie (Brachycamacus gyrommatus gen. n., sp. n.) (Coleoptera: Curculionidae: Entiminae: Naupactini) de gorgojos preservados en ámbar procedente de la República Dominicana. La nueva subtribu se diferencia de la subtribu nominal por los siguientes caracteres: un diente prominente en el profémur, inserción de las antenas en la parte media del rostro, todas las tibias con mucros, márgenes internos de las tibias denticulados, los dos tercios apicales de las protibias ensanchados y un escapo de la antena muy corto. Esta es la segunda especie de gorgojo de trompa ancha descrita en ámbar dominicano.

Résumé en Français
Brachycamacina, une nouvelle sous-tribu de la tribu Naupactini (Coleoptera: Curculionidae Entiminae) dans l'ambre de la République Dominicaine
Une nouvelle sous-tribu (Brachycamacina n. subtribe.), genre et espèce (Brachycamacus gyrommatus gen. N., sp. n.) (Coleoptera: Curculionidae: Entiminae: Naupactini) de charançons sont décrites à partir d'ambre Dominicaine. La nouvelle sous-tribu diffère de la sous-tribu nominative de la tribu Naupactini par la combinaison des caractères suivants: dent proéminente sur le profémur, insertions d'antennes au milieu du rostrum, tous les tibias avec des mucros, marges intérieures des tibias denticulés, les deux tiers apical des protibias élargis et une très courte hampe. Il s'agit du deuxième charançon au nez large décrit à partir d'ambre dominicaine.
