Coffee Berry Borer

Resumen. Solenopsis cf. picea, también conocida como "la negrita", es una hormiga abundante en los sistemas cafeteros de la zona de Risaralda (Colombia), donde anida en el suelo y se encuentra tanto en cafetales de sombra como monogenéricos. Estudios realizados en campo y en laboratorio han demostrado que depreda sobre la broca del café, convirtiéndola en un organismo que podría

The bethylid wasps Cephalonomia stephanoderis Betrem and Prorops nasuta Waterston are parasitoids of the coffee berry borer, Hypothenemus hampei (Ferrari), the most serious insect pest of coffee worldwide. Recent studies on the host location behaviour of these parasitoids have shown that females are attracted to volatile compounds released by immature stages and dust/frass of H. hampei. Also, these studies have reported that the locomotory behaviour of parasitoids is influenced by contact chemical cues from host dust/frass. In this study, we investigated the responses of females of both species to volatiles and contact cues from dust/frass from different sources. Volatiles from dust/frass from H. hampei-infested coffee and maize infested with Sitophilus sp were attractive to P. nasuta females. In contrast, C. stephanoderis females were only attracted to the volatiles from dust/frass from H. hampei-infested coffee. Volatiles from an artificial diet used for rearing H. hampei were not attractive to females of both species. The effect of methanolic extracts from dust/frass from different sources on the patch-searching time of parasitoids was analysed using the Ethovision software. P. nasuta females spent more time in the patches treated with extracts of dust/frass from H. hampei-infested berries, artificial diet, and from maize infested with Sitophilus sp than on patches treated with dry coffee extract or solvent control. C. stephanoderis females spent more time on patches treated with dust/frass extracts from H. hampei-infested berries and artificial diet than on patches treated with an extract of dust/frass from maize infested with Sitophilus sp, an extract of dry coffee, and methanol control.

Cry1B and Cry3 proteins from Bacillus thuringiensis are toxic to beetles such as the colorado potato beetle and the cottonwood leaf beetle. We report the development of a suitable rearing, bioassay method and the toxicity of these Cry proteins to coffee berry borer first instar larvae.

Fungal endophytes are quite common in nature and some of them have been shown to have adverse effects against insects, nematodes, and plant pathogens.Our research program is aimed at using fungal endophytes-mediated plant defense as a novel biological control mechanism against the coffee berry borer, the most devastating pest of coffee throughout the world. A survey of fungal endophytes in

Evaluation of alcoholic attractants in a handmade trap for monitoring and control of the coffee berry borer Hypothenemus hampei (Ferrari) This assay was based on the need of developing strategies to control the coffee berry borer Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae) affordable by farmers. In the locality of Caspo, Lara State, Venezuela, the capture of adults of the insect using

The coffee berry borer (CBB) Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae) was accidentally introduced into México in 1978, and rapidly became the main pest of coffee. As an exotic pest, its management has been mainly based on biological control ...

Biology of Coffee Berry Borer H. hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae) under laboratory conditions The berry borer (Hypothenemus hampei) is the main insect-pest in the coffee producer countries. In this paper the biological cycle of the insect was studied in a material collected in 2004 in Andrés Eloy Blanco County, Lara State, Venezuela. The study was conducted at the Entomology Laboratory of INIA-Lara, under mean temperature and relative humidity of 27.1°C and 65.3 %, respectively. The average duration of the insect phases was 4.21 days for egg, 11.15 days for larvae, 2.66 days for pre-pupa, 5.29 days for pupa, and 103,3 days for adult female. The paper also describes some morphological characteristics of each phase. The following two larval instars were found: L1, with an average width of the cephalic capsule of 0.33 mm, and L2, with 0.52 mm wide. The pre oviposition period lasted 5.1 days, the egg fertility was 99.2 %, the fecundity was 43.0 eggs per adult fem...

Hypothenemus hampei is the main coff ee pest in the Amazon and worldwide. Although coff ee cultivation exists in the State of Amazonas, there is no information regarding the behavior of this species population in this region of Brazil. Since the Amazon region is a favorable environment for H. hampei, the present study aimed to investigate this insect population in the following cultivation systems implanted in the municipality of Humaitá, Southern Amazonas: i) coff ee in native forest (CNF), ii) coff ee intercropped with cupuaçu and açaí (native Brazilian fruits) (CCA) and iii) coff ee in monoculture (MC). Also, the climatic and phenological parameters of the plant were used in relation with the population dynamics of the insect. For that, ten baited traps were installed in each fi eld for the monthly sampling of the H. hampei population from July/2018 to June/2019. The highest population abundance of the insect was observed during the coff ee fl owering season, mainly in monoculture crops, when compared to the other intercropped fi elds. The total mean value of the insect population observed in the three environments evaluated was highest in August/2018, with a recorded value of 1749. The increase in rainfall indexes occurred simultaneously with a decrease in the insect population; this coincides with the end of the fl owering season (October/2018, 161.8 mm) and the beginning of grain formation (November/2018, 234.8 mm). The lowest abundance of the insect observed in the coff ee fi elds in native forest, with an abundance of 83 (CNF), indicates that the local biodiversity disfavors the population size of the pest in the environment. These results suggest that phenological phases of conilon coff ee and the infl uence of climatic conditions can result in changes in the population dynamics of the H. hampei. Coff ee agroforestry systems are more promising to maintain this population at low levels.
