Entomopathogenic fungi are key components of biological pest control programs. Among these, Metarhizium anisopliae is one of the best-studied and has been demonstrated to be particularly effective against coleopterans. The native M. anisopliae CPMa1502, previously selected for its insecticidal activity against Demotispa neivai (oil palm fruit scrap...

Using chemical insecticides in IPM is possible and could be sustainable. To find a sustainable alternative to control S. impressella, we assessed the biological activities of five commercial formulations of Bacillus thuringiensis. First, these formulations were evaluated under laboratory conditions. No differences were observed between the commerci...

The implementation of trapping nets of Rhynchophorus palmarum, the trap with canvas, baited with the aggregation pheromone Rhynchophorol and kairomone (1,000 cc of the molasses water mixture in a 2:1 proportion, and 300 g of sugar cane), is constituted in an effective tool for monitoring weevil populations. This trapping system progressively reduce...

Rhynchophorus palmarum (L.) (Coleoptera: Dryophthoridae) is an important pest in oil palm plantations, and its populations are monitored through rhynchophorol pheromone-baited traps. To optimize the release of rhynchophorol in high-density polyethylene diffusers, five calibers (2, 3, 4, 5, and 6) were evaluated. The experiment was conducted under a...

Stenoma impressella is one of the most important defoliator pests in oil palm plantations in Colombia. To identify an alternative method for its control was characterized biologically and molecularly two strains of Cordyceps cateniannulata (CPIsp1201 and IPIsp1201) and three strains of Beauveria bassiana (CPBb0502; CPBb0411; CPBb0404) against S. im...

Demotispa neivai (Bondar) is an economically important pest of oil palm, Elaeis guineensis Jacq., plantations in Colombia. During our search for alternatives to conventional chemical insecticides for controlling D. neivai, we initially screened 50 isolates of various entomopathogenic fungi against adults and larvae. At a concentration of 1 × 107 co...

This guide book, presents information on the main insect pests affecting cultivars of oil palm in Colombia. It was included the most important species which the oil palm farmers deal on. So farmers can have a handy book publication, to understand the main characteristic and behavior of these insects that will help them to combat these pests in a su...

Metarhizium anisopliae CPMa1502 as potential biological control agent for Demotispa neivai: A first approach to biopesticide development Entomopathogenic fungi are key components of modern biological pest control since they are innocuous to both human health and the environment and may be as effective as synthetic pesticides. Among these, Metarhiz...

Establecimiento de redes de trampeo para el control de Rhynchophorus palmarum en el cultivo de palma de aceite.

The oil palm, Elaeis guineensis Jacquin, is an allogamous and monoecious plant that is mainly pollinated by insects such as Mystrops costaricensis Gillogly (Coleoptera: Nitidulidae) and Elaeidobius kamerunicus Faust (Coleoptera: Curculionidae). To determine the relationship between inflorescences and pollinators as well as the relationship between...

El raspador de frutos de la palma de aceite Demotispa neivai (Bondar) (Coleoptera: Chrysomelidae), es una de las plagas de mayor importancia en el cultivo de la palma de aceite en Colombia, debido al daño que causa al alimentarse de la epidermis de los frutos . D. neivai también puede encontrarse causando daño en las flechas de palmas en vivero y e...

Introducción El escarabajo rinoceronte o torito Strategus aloeus L. (Coleoptera: Scarabaeidae) es una de las plagas de mayor importancia en palma de aceite menores a tres años en Colombia. El daño es causado por el adulto macho a través de una galería que realiza hasta llegar cerca del bulbo de la palma como parte de su hábito alimentario y de repr...

Este estudio ha permitido ofrecer a los palmeros de Colombia, cepas formuladas con los hongos Purpureocillium lilacinum (CPPl0601) para el control de L. gibbicarina y Metarhizium anisopliae (CPMa1502), para el control de D. neivai, en plantaciones infestadas con estas plagas.

El raspador de frutos de la palma de aceite, Demotispa neivai, causa la pérdida de aceite debido a la lesión que produce en la epidermis al alimentarse de los frutos. Con el fin de conocer mejor los hábitos de este insecto y poder controlarlo más eficientemente, se inició una investigación sobre su biología y enemigos naturales. Para esto, bajo con...

La escama blanca del cocotero, Parlagena bennetti Williams, 1969 (Hemiptera: Diaspididae), es una plaga de importancia económica en plantaciones de cocotero, Cocos nucifera L. (Arecaceae), en Honduras y en las Islas de San Andrés y Trinidad en el Caribe. En enero de 2015, P. bennetti se detectó por primera vez en Colombia continental en la Zona Cen...

El macho de Rhynchophorus palmarum libera pequeñas cantidades de la feromona de agregación en el ambiente, de modo que ocasiona en otros individuos adultos de su especie, tanto hembras como machos, la agregación en el sitio donde la produce. El uso de trampas hace parte del manejo de la enfermedad conocida como Anillo Rojo –hoja corta (AR). En zona...

The white coconut scale, Parlagena bennetti Williams, 1969 (Hemiptera: Diaspididae) is reported for the first time on New Zealand flax, Phormium tenax J.R. Forst. & G. Forst. (Xanthorrhoeaceae), coconut, Cocos nucifera L., Manila palm, Veitchia merrillii (Becc.) H.E. Moore, oil palm, Elaeis guineensis Jacq. and an oil palm hybrid OxG: E. oleifera x...
