Item type: Item , First record of Anastrepha pseudoparallela Loew (Diptera: Tephritidae) infesting passion flowers in Peru(Universidad Nacional Mayor de San Marcos, 2020) Salazar-Mendoza, P.; Ninahuamán-Calderón, A.; Fernández, C.G.; Strikis, P.C.Several species of the genus Anastrepha Schiner are associated to different hosts and have a great economic importance in fruit crops of the Neotropical region. Ripe and unripe fruits of six passion flowers species were sampled in Oxapampa during 2016 and 2018. Larvae of Anastrepha pseudoparallela Loew (Diptera: Tephritidae) were detected infesting fruits of Passiflora ambigua Hemsl and Passiflora quadrangularis L. For the first time, this fruit fly species is recorded attacking fruits of passion flowers in Peru.Item type: Item , New quarantine cold treatment for medfly Ceratitis capitata (Diptera: Tephritidae) in pomegranates(De Gruyter, 2025) Quenta, E.C.; Huaynate, C.C.; Ruidias, M.O.; Arambulo, T.T.; Febres, G.The medfly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is one of the most important agricultural pests worldwide due to its impact on harvest and market restrictions for host fruits in several countries. Pomegranates (Punica granatum [L.]; Lythraceae) are sensitive to chilling injuries caused by existing quarantine cold treatments. This study aimed to establish a new cold-Treatment schedule at 5°C for fresh pomegranates by determining the required exposure time to mitigate C. capitata in the pomegranate 'Wonderful' variety. The third-instar larva was deemed the most cold-Tolerant instar and was used for this study. The combination of 5.2°C for 36 days achieved 100% mortality.Item type: Item , Biological cycle and morphological characterization of the developmental states of Tuthillia cognata (Hemiptera: Psyllidae) in camu camu(Instituto de Investigaciones de la Amazonía Peruana, 2023) Campos-Celestino, V.E.; Velazco Castro, E.V.; Guerra-Ambrosio, B.; Sanchez-Choy, J.The jumping louse, Tuthillia cognata (Hemiptera: Psyllidae) is a pest that causes severe deformations in the leaf buds of Myrciaria dubia (camu camu) in the Peruvian Amazon, therefore, a study was carried out with the objective of determining the morphological characteristics of each stage of development, the duration and longevity of T. cognata adults in young shoots of camu camu. The research was carried out under laboratory conditions (temperature: 26,9 ± 2°C, relative humidity: 6,6 ± 5% and 12:12 h Light: Dark) in Pucallpa, Peru. Morphological characteristics of each stage of development, duration and longevity of T. cognata adults in young shoots of camu camu were determined. The duration from egg to adult was 17,8 ± 0,6 (12 to 23) days and longevity for females was 38,6 ± 1,3 (37 to 40) days and for males 35,6 ± 1,5 (34 to 38) days.Item type: Item , Diversity in the invasive cacao pathogen Moniliophthora roreri is shaped by agriculture(Wiley, 2022) Cedeño-Amador, S.; Zambrano, R.; Cedeño-Amador, S.; Córdova-Bermejo, U.; Casas, G.G.; García-Zurita, N.; Sánchez-Arévalo, J.; Arévalo-Gardini, E.; Dávila, D.; Ruiz, J.; Pinchi-Dávila, X.; Quispe-Chacón, Z.R.; Chia-Wong, J.A.; Hurtado-Gonzales, O.; Rodríguez-Callañaupa, C.A.; Maldonado-Fuentes, C.; Pérez-Callizaya, E.; Leiva-Espinoza, S.; Oliva-Cruz, M.; Guevara-Ruiz, D.; Torres-Rojas, E.; Johnson, E.; Phillips-Mora, W.; Aime, M.C.Frosty pod rot disease of cacao (FPR), caused by the fungus Moniliophthora roreri, has severely impacted the production of cocoa in Latin America since its discovery. Prior to the 1950s, FPR was known only from Colombia and Ecuador. However, beginning in the 1970s, its geographical range has dramatically expanded throughout most of the cacao-producing regions of the Americas. The origin of the pathogen remains unknown. In this study, we evaluated the genetic diversity of M. roreri from areas spanning, as much as possible, its current geographical range using simple-sequence repeat markers and a publicly available single-nucleotide polymorphism data set. Two hotspots of genetic diversity were found: coastal Ecuador and the inter-Andean Magdalena Valley of Colombia, neither of which correspond to the Amazonian origin of the host. However, both areas were early centres of intense cultivation of cacao. Our results indicate that M. roreri was introduced into both areas from its centre of origin, where intensive cacao cultivation probably led to the increase of inoculum and further dissemination of the disease. Current invasions can be traced to two genotypes responsible for all known instances of the pathogen in Central America, the Caribbean, Peru and Bolivia. We also report for the first time M. roreri in Maynas (Peruvian Amazon), which is probably the result of a recent introduction from Colombia.Item type: Item , Guía de Buenas Prácticas en la producción de porcinos(2020) Servicio Nacional de Sanidad Agraria - SENASALa guía brinda los lineamientos básicos mínimos que permitan a los medianos y pequeños productores porcinos orientar y asegurar la inocuidad de los alimentos, la protección del medio ambiente y de las personas que trabajan en la explotación
