Aphelinus Diaspidis Howard

First report of Aphelinus semiflavus Howard, 1908 (Hymenoptera: Aphelinidae) in Brazil.

Cardinium in Plagiomerus diaspidis (Hymenoptera: Encyrtidae).

The bacterial symbiont Cardinium (Bacteroidetes) was previously implicated in the thelytokous reproduction of the parasitoid Plagiomerus diaspidis Crawford (Hymenoptera: Encyrtidae). Horizontal transmission of the symbiont among the cactus scale Diaspis echinocacti Bouché (Homoptera: Diaspididae) and its hymenopteran parasitoids has been suggested. In this study, the bacteria associated with D....

to test whether termites of the Cryptotermes domesticus species might be able to discriminate between different sizes of wood. The team constructed experiments that presented termites with blocks of wood with a standard crosssectional diameter of 20x20 mm but of either 20 mm or 160 mm length. The insects were placed in a gap between the two faces of the timber blocks so that they were not able ...

Several microcomputer-controlled analytical instruments are described that illustrate certain automation concepts, focus attention on some recent developments, and help us to envisage what might be introduced during the 1980's. New types of stop-flow analyzers are shown to have considerable promise for routine and investigative kinetic and equilibrium analytical/clinical methods. Throughputs of...
