Resumo: | Leucothyreus femoratus Burmeister (Coleoptera: Scarabaeidae) is an important insect pest of oil palm plantations, because larvae and adults feed on plant roots and leaves, respectively. This suggests the necessity of comprehending the pest’s feeding and behavioral habits for pest management. Food consumption and injury to leaves of Elaeis guineensis Jacq. (Arecales: Arecaceae, African oil palm) by adults of L. femoratus in Colombia were studied. Locomotion of adults was evaluated with respect to 6 behaviors, i.e., emergence, hiding in the ground, walking, flying, feeding, and mating. In addition, larvae were collected from the roots of other plants found in the oil palm plantation in order to determine possible alternative hosts. Leaf consumption per adult L. femoratus was 13 mm 2 /day/insect (r 2 = 19.33, P < 0.0001). Leaf injury was in the form of squares or rectangles and cumulative defoliation reached 15.5% in 60 days. The insect showed predominantly nocturnal feeding and mating (r 2 = 95.53, P < 0.05; r 2 = 207.01, P < 0.05, respectively). Larvae of L. femoratus were found in abundance on the roots of Croton trinitatis Millsp. (Euphorbiaceae, road side croton) and Imperata cilindrica (L.) P. Beauv. (Poaceae, cogon grass). The feeding habits of larvae and adults of this insect may be main factors in their adaptation to oil palm plantations. The understanding of the feeding habits and behaviors of L. femoratus are important to define strategies for the management of their populations in oil palm plantations. |

Esto sugiere la necesidad de comprender la alimentación del insecto y los hábitos de comportamiento para el manejo de esta plaga. El consumo alimentario y el daño a las hojas de Elaeis guineensis por parte de adultos de L. femoratus en Colombia fueron estudiados. La actividad locomotora de los adultos se evaluó con respecto a 6 comportamientos, es decir, emergencia y ocultamiento en el suelo, caminata, vuelo, alimentación y apareamiento. Además, las larvas se recolectaron en las raíces de otras plantas que se encuentran en plantaciones de palma de aceite con el fin de determinar los posibles hospederos alternos. El consumo foliar de L. femoratus por adulto fue de 13 mm 2 /día/insecto (r 2 = 19.33, P < 0.0001). La lesión en la hoja presentó una forma de cuadrados o rectángulos y la defoliación acumulada alcanzó el 15.5% en 60 d. El insecto mostró predominantemente hábitos de alimentación y apareamiento nocturnos (r 2 = 95.53, P < 0.05; r 2 = 207.01, P < 0.05). Las larvas de L. femoratus fueron encontradas en abundancia, en las raíces de Croton trinitatis Millsp. (Euphorbiaceae, croto) e Imperata cilindrica (L.) P. Beauv. (Poaceae, vende aguja). Los hábitos de alimentación de las larvas y adultos de este insecto puede ser el factor principal para su adaptación en plantaciones de palma de aceite. La comprensión de los hábitos alimenticios y el comportamiento de L. femoratus son importantes para definir estrategias en el manejo de sus poblaciones en plantaciones de palma de aceite.engFlorida Entomologistv. 96, n. 1, p. 55- 63, mar. 2013DefoliationElaeis guineensisBehaviorHost plantsRoot feederFeeding habitComportamientoDefoliaciónFitófagos plantas hospederasRizófagosLeucothyreus femoratus (Coleoptera: Scarabaeidae): feeding and behavioral activities as an oil palm defoliatorinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALartigo.pdfartigo.pdftexto completoapplication/pdf594637https://locus.ufv.br//bitstream/123456789/23545/1/artigo.pdfec2895b282eadc205f02f68732553f0fMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81748https://locus.ufv.br//bitstream/123456789/23545/2/license.txt8a4605be74aa9ea9d79846c1fba20a33MD52123456789/235452019-02-15 11:04:44.008oai:locus.ufv.br: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Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452019-02-15T14:04:44LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
