‘Retournement’ of the aedeagus in Curculionidae (Coleoptera, Curculionoidea) [PDF]
, 2013 Retournement or turning of the aedeagus about its longitudinal axis through about 180o during development is known in Chrysomeloidea (Coleoptera). This change in the orientation of the organ may be observed during the postembryonic development.

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Kenya
EFSA Journal, Volume 22, Issue 4, April 2024.Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Kenya. The relevance of any pest for

Mechanical damage in cotton buds caused by the boll weevil
Pesquisa Agropecuária Brasileira, 2003 The boll weevil (Anthonomus grandis Boheman) causes high levels of bud abscission in cotton plants due to feeding or oviposition punctures. It has been reported that abscission is mainly due to enzymes present in the insect's saliva, but mechanical ...
