Subject:
Coccinellidae; cerrado; ecosystems; habitats; insects; natural enemies; parasitoids; rain forests; Brazil
Abstract:
... Current knowledge on coccinellids is primarily focused on their role as natural enemies of soft-bodied insects. However, there is a great diversity of coccinellid parasitoid species that are less studied. Here, we describe new records of coccinellid parasitoids with emphasis on new host–parasitoid interactions in 11 sample sites in Brazil. We collected 122 coccinellid individuals parasitized by si ...

Abstract:
... Bioinsecticides are being increasingly used to protect vegetable crops against herbivores, but data on the side effects of such strategy on the third trophic level are still required.

The selectivity of various entomopathogens and one insecticide (chlorpyrifos = positive control) to Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) was evaluated in the laboratory, using the protocol established by the Working Group on “Pesticides and Beneficial Organisms” of the IOBC. The evaluated parameters were parasitism (%), adult emergence (%), and product repellency to the pa ...

Abstract:
... Ecological immunology assumes that the host immune efficiency is correlated with its survival after pathogen challenge. To test this hypothesis, we challenged Phyllophaga polyphylla (Bates) larvae with the naturally occurring fungus Metarhizium pingshaense on two consecutive years (2011 and 2012). In each year, we injected the blastospores of M. pingshaense and then used levels of prophenoloxidase ...
