Developing pheromone traps and lures for Maruca vitrata in Benin, West Africa por Downham, M.C.A., Tamò, Manuele, Hall, D.R., Datinon, B., Adetonah, S., Farman, D.I.

“…Residue analysis showed that vial lures exposed for 2 weeks in the field still contained 73% of the initial amount of (E,E)-10,12-hexadecadienal, compared to rubber septa dispensers, which only retained 22%. Females comprised 11–50% of total catches, confirming earlier, unexpected results for synthetic lures. …”

High-milking sheep have a lower ovulation rate and tend to yield fewer embryos in response to superovulation and intra uterine artificial insemination por Merai, Afef, Dattena, Maria, Casu, Sara, Rekik, Mourad, Lassoued, Narjess

“…Furthermore, there was a tendency for high‐producing ewes to yield fewer embryos than low‐producing females (5.3 ± 3.46 vs 9.18 ± 5.11; p = .09). No differences were observed between ewes in both genetic groups with regard to the number of embryos of grades 1, 2 and 3. …”

On-farm description and status of Nuer (Abigar) cattle breed in Gambella Regional State, Ethiopia por Minuye, N., Abebe, G., Dessie, Tadelle

“…This study was conducted in Gambella Regional State (GRS) in order to characterize the Abigar cattle breed phenotypically at its breeding tract.It was done purposively in four selected districts of the region using extensive field surveys, morphological measurements and focused group discussions on the origin, distribution, current status and future threats, production and reproduction characteristics of Abigar cattle at its production environment.By using semi-structured questionnaire, 160 cattle owners were interviewed and qualitative and quantitative data were recorded for mature 200 female and 100 male cattle.Milk yield monitoring of 95 lactating Abigar cows was assessed in and around Gambella district for three months long.The data were entered into Excel sheet and analyzed using SPSS (2007) software package.The study has shown that Abigar cattle are the most dominant both in the Nuer and Anywaa zones of the region.The breed possesses unique features that can be used in identifying the breed from other indigenous breeds.The breed has got large body size, long-curved horns, gray and white dominant coat colors as well as ease of management by all gender groups due to its recognized docile character.The average age at puberty, age at first calving and calving interval were found to be 36.2,42.5 and 14.1 months, respectively under extensive management.In addition, the breed has better production and reproduction capabilities despite the high heat load, recurrent drought and repeated disease prevalence in the region.However, a decreasing trend of the breed had been noticed in the studied areas in recent years mainly due to disease outbreaks and lack of medication, ethnic conflicts, cattle raiding and high expansion of commercial crop production.Thus, a well-coordinated and community driven participatory in situ conservation strategy has great significance to ensure the maintenance, future use and improvement of the breed for enhancement of food security of the pastoral and agro-pastoral communities in the region.…”

A genetic linkage map of water yam (Dioscorea alata L.) based on AFLP markers and QTL analysis for anthracnose resistance por Mignouna, Hodeba D., Mank, R.A., Ellis, T.H.N., Bosch, N.V.D., Asiedu, Robert, Abang, Mathew M., Peleman, J.

“…The F1 was obtained by crossing two improved breeding lines, TDa 95/00328 as female parent and TDa 87/01091 as male parent. Since the mapping population was an F1 cross between presumed heterozygous parents, marker segregation data from both parents were initially split into maternal and paternal data sets, and separate genetic linkage maps were constructed. …”

Role of Embryonic and Maternal Genotype on Prenatal Survival and Foetal Growth in Rabbit por Naturil-Alfonso, C., Marco-Jiménez, Francisco, Jiménez-Trigos, E., Saenz-de-Juano, M. D., Viudes-De-Castro, María P., Lavara, R., Vicente, José Salvador

“…Laparoscopy was performed at Day 14 to determine implantation rate. Recipient females were slaughter at Days 14, 24 and 30 (12, 24, and 14, respectively) to determine the number of live foetuses and the weight of live foetuses, foetal placenta and maternal placenta. …”

Genetic analysis of physiological components of salt tolerance conferred by Solanum rootstocks. What is the rootstock doing for the scion? por Asins, María J., Bolarin, M. C., Pérez-Alfocea, Francisco, Estan, M. T., Martínez-Andújar, Cristina, Albacete, Alfonso, Villalta, Irene, Bernet, Guillermo P., Dodd, Ian C., Carbonell, Emilio A.

“…Here, a commercial hybrid tomato variety was grafted on two populations of recombinant inbred lines developed from a salt-sensitive genotype of Solanum lycopersicum var. cerasiforme, as female parent, and two salt-tolerant lines, as male parents, from S. pimpinellifolium, the P population, and S. cheesmaniae, the C population, to identify an easy screening method for identifying rootstocks conferring salt tolerance in terms of fruit yield. …”

Quality of aphid honeydew for a parasitoid varies as a function of both aphid species and host plant por Monticelli, Lucie S., Tena, Alejandro, Mathilda, Idier, Amiens-Desneux, Edwige, Desneux, Nicolas

“…In this context, we assessed the relationship between the adult fitness (in terms of longevity and fecundity) of the aphid parasitoid Aphelinus abdominalis (which prefer attack aphid species belonging to the Macrosiphini tribe), fed on honeydew produced by 19 different plant-aphid combinations, and parasitoid preference (i.e., the choice of female to oviposit) and ability to produce offspring in these combinations. …”

Biological control of the citrus leafminer 25 years after its introduction in the Valencia citrus growing area (Spain): a new player in the game por Mansour, D, Pérez-Hedo, Mertixell, Catalán, José, Karamaouna, F., Braham, M., Jaques, Josep A., Urbaneja, Alberto

“…Among the predators collected, the density of Pilophorus clavatus, a zoophytophagous mirid recently detected in Spanish citrus, was positively correlated with P. citrella predation. In the laboratory, females of P. clavatus preyed actively on second-instar P. citrella. …”
