	abstract = {The coffee berry borer, Hypothenemus hampei, is the most important pest of coffee throughout the world, causing losses estimated at US $500 million/year. The thrips Karnyothrips flavipes was observed for the first time feeding on immature stages of H. hampei in April 2008 from samples collected in the Kisii area of Western Kenya. Since the trophic interactions between H. hampei and K. flavipes are carried out entirely within the coffee berry, and because thrips feed by liquid ingestion, we used molecular gut-content analysis to confirm the potential role of K. flavipes as a predator of H. hampei in an organic coffee production system. Species-specific COI primers designed for H. hampei were shown to have a high degree of specificity for H. hampei DNA and did not produce any PCR product from DNA templates of the other insects associated with the coffee agroecosystems. In total, 3,327 K. flavipes emerged from 17,792 H. hampei-infested berries collected from the field between April and September 2008. Throughout the season, 8.3\% of K. flavipes tested positive for H. hampei DNA, although at times this figure approached 50\%. Prey availability was significantly correlated with prey consumption, thus indicating the potential impact on H. hampei populations.},

	abstract = {The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), is the most important constrain for coffee production throughout the world. Knowledge on the emergence pattern of H. hampei females to infest new berries is crucial to effectively plan control measures. In this laboratory study, we assessed the development of immature stages and the emergence pattern of H. hampei females from the berries by exposing them to temperatures that are typical for high-altitude plantations (>=1,700 m above sea level (mas))) or when coffee is grown under shade trees (20-22[degree]C), and optimum altitude plantations (1,200-1,600 masl) or nonshaded coffee (25-30[degree]C). Fecundity and emergence pattern of H. hampei females from coffee berries varied with temperature. Temperature played a crucial role determining the rate of H. hampei development and therefore the emergence of the females to start a new infestation cycle. The emergence and colonization phases of new colonizing females in coffee plantations with mean temperatures of 20, 25, or 30[degree]C would take place at different moments in the development of the coffee berries, and in some cases more than once. The implications of our findings for an improved, site-specific timing of control interventions against H. hampei are discussed.},

Among the various organic sources of nutrients / amendments tested, application of farm yard manure (FYM) (1.25 t/ha) + neem cake (0.75 t/ha) + azophos (25 kg/ha) followed by FYM + neem cake in two equal splits at four months interval was found to be consistently effective in reducing the infestation of coffee berry borer throughout the period of observations and also less preferred for feeding and oviposition by coffee berry borer and thus exhibited high inhibition for feeding (antifeedant) and ovipositional deterrency. The organics treated plots recorded significantly prolonged larval duration due to neem and it was maximum in FYM [plus or minus] neem cake [plus or minus] azophos (18.76 [plus or minus] 3.14 days) as compared to 13.41 [plus or minus] 2.25 in inorganic NPK. The growth index of berry borer was the least (4.24) in the treatment with FYM [plus or minus] neem cake [plus or minus] azophos as compared to 6.87 in inorganic NPK.},

	abstract = {The present study was conducted in coffee plantations of Chiapas to evaluate the establishment of three African parasitoids of the coffee berry borer Hypothenemus hampei (CBB), that have been released in this region for biological control purposes. During the inter cropping period were sampled fruits infested with the CBB from 31 coffee plantations in four municipalities. The infested fruits were dissected in order to detect the presence of any of the three species of CBB parasitoids: Cephalonomia stephanoderis, Prorops nasuta and Phymastichus cofea. We were also looking for parasitism by the native parasitoid Cephalonomia hyalinipennis. For analysis, we considered several variables, such as parasitoid earlier releases, species of coffee planted, altitude of sites, the prior existence of rural young, presence of rivers and conditions of coffee (careful or careless). Tis data was analysed in a Generalized Lineal Model. The results showed that C. stephanoderis was found in 67,7\% of samples, and the percent of parasitism ranged from 0,33 to 26\%. C. hyalinipennis was only detected in a single sample and its parasitism was 3\%. P nasuta and P. cofea were not found in the samples. The presence of C. stephanoderis was correlated with altitude, the species of coffee and the number of previous releases, among others. In this study we confrm the establishment of C. stephanoderis, 20 years after its first release in coffee plantations of Chiapas, Mexico.},

	abstract = {Hypothenemus hampei is the most important insect pest of coffee and has spread to most coffee-growing countries worldwide. There have been very few studies and none have addressed the population genetics of the beetle using microsatellite markers. In the present study, 683 individuals collected from 37 locations in 18 countries worldwide were screened at nine polymorphic microsatellite loci. Sixty-five out the 683 and six additional individuals were analyzed on a 400-bp fragment of the mitochondrial cytochrome oxidase I gene. Bayesian clustering analysis and phylogenetic approaches were used to infer the genetic structure of H. hampei over the sampling that encompassed almost all its range. Microsatellite markers made it possible to achieve sufficiently significant power for the delineation of five morphocryptic evolutionary units. Supported by 27 new COI haplotypes, an unexpected considerably high level of genetic differentiation and genetic divergence was revealed between five geographically delineated clusters. Both markers and approaches showed that the clusters included specimens from (1) Ethiopia, (2) Kenya and Uganda, (3) Brazil, (4) Central America excluding Jamaica, and (5) all samples from Asia, West Africa, and Jamaica. These findings clearly suggest the existence of a {\textquoteright}species complex in H. hampei{\textquoteright}.

	abstract = {It is well established that plants infested with a single herbivore species can attract specific natural enemies through the emission of herbivore-induced volatiles. However, it is less clear what happens when plants are attacked by more than one species. We analyzed effects of volatile emissions of Coffea arabica plants upon species herbivory by the coffee leaf miner (Leucoptera coffeella), coffee berry borer (Hypothenemus hampei) and coccineal (Coccus viridis and Planococcus citri) interactions with predatory Vespidae. The coffee crops most attacked by L. coffeella presented a higher number of concentrations of volatile compounds. These results indicate that volatiles from C. arabica infested by L. coffeella may inform Vespidae adults about the presence of the most suitable stage of their prey.},

	abstract = {Cephalonomia stephanoderis and Prorops nasuta are two bethylid wasps released into several Latin American countries for classical biological control of coffee berry borer, Hypothenemus hampei, the most serious insect pest of coffee worldwide. Recent studies on the host location behaviour of these parasitoids have shown that females of both species are attracted to volatile compounds released by immature stages and dust and frass of H. hampei. In this study, we investigated the role of the contact chemicals present in dust and frass of H. hampei on the behaviour of P. nasuta and C. stephanoderis females. Parasitoids remained longer on patches treated with methanol extracts than on acetone and hexane extracts. Females spent more time on the patch treated with the methanol extract of dust and frass than on the patches treated with the methanol extract of dry coffee and methanol control. The concentration of the methanol extracts from dust and frass influenced the locomotory activity of parasitoids of both species. The time that females spent in the patch tended to increase as the concentration of the methanol extracts increased. A further experiment aimed to identify other behavioural descriptors and gain a deeper understanding of the mechanisms underlying the response of parasitoids to methanol extracts was performed. Females of both species spent more time, covered more distance, turned more (per unit time and per unit distance), and decreased their speed when they contacted patches treated with methanol extracts in comparison to patches treated with methanol control.},
