Flower visits of cockroaches (Insecta: Blattodea) in the Iberian Peninsula: Are they neglected pollinators?

Rotation of the iberian peninsula.

Jones and Ewing (1) have presented seismic profiler data from the Bay of Biscay which allows a 120 anticlockwise rotation of the Iberian peninsula between Eocene and Middle to Upper Miocene times. They refer several times to the fact that this va'ue is appreciably less than a rotation of 220, which they believe resulted from our paleomagnetic study of the Lisbon Volcanics (2). We must point out...

The Blattodea s.s. (Insecta, Dictyoptera) of the Guiana Shield

Here we provide a checklist of cockroach species known from areas within the Guiana Shield based on literature records and new field collection. We give records of sixteen species collected in Guyana, eight of which are new records for Guyana and one of which is a new generic record for the entire Guiana Shield. We also provide a description for a geographically disparate species of Calhypnorna...

Detection of malathion and chlorpyrifos resistance mechanism in German cockroaches (Blattella germanica, Insecta: Blattodea: Blattellidae) using piperonyl butoxide and tributyl phosphorotrithioate

Introduction: German cockroach (Blattella germanica, Insecta: Blattodea: Blattellidae) is considered one of the most common household pests which can transfer pathogenic agents and also cause allergic reactions. Frequent and uncontrolled spraying caused resistance in German cockroach to insecticides. In this study we aimed, to determine the malathion and chlorpyrifos resistance mechanism ...
