the effects of temperature on the development fecundity and mortality of eretmocerus warrae is eretmocerus warrae better adapted to high temperatures than encarsia formosa
Pest Management Science, 2019Co-Authors: Tao Wang, Michael A Keller, Katja HogendoornAbstract:BACKGROUND: Eretmocerus warrae (Hymenoptera: Aphelinidae) is a parasitoid of the glasshouse whitefly, Trialeurodes vaporariorum (Hemiptera: Aleyrodidae). Here, we compare its potential as a biological control agent at high temperatures to that of Encarsia formosa (Hymenoptera: Aphelinidae), a wasp which is widely sold for control of T. vaporariorum. RESULTS: Eretmocerus warrae attained the highest estimated developmental rate at 31.4 °C and the maximum oviposition rate at 30.5 °C. Developmental times of E. warrae at fluctuating temperatures that simulate night‐day patterns were similar to those predicted based on constant temperatures. Above the optimum temperature, E. warrae tolerated higher constant temperatures than En. formosa during development and as adults. Using a ramping temperature approach, the critical thermal maximum for adult E. warrae was significantly higher than that of adult En. formosa. CONCLUSION: Eretmocerus warrae is better adapted to high temperatures than En. formosa, and could therefore be a complementary or superior biological control agent during summer months in hot regions. © 2018 Society of Chemical Industry

Primary studies on the parasitoid fauna of Coccoidea in cultivated and non-cultivated areas in the east Mediterranean region of Turkey
Anzeiger für Schädlingskunde Pflanzenschutz Umweltschutz, 1998Co-Authors: C. Sengonca, I. Karaca, N. Uygun, M. SchadeAbstract:The parasitoid fauna of Coccoidea in cultivated and noncultivated areas was studied in the east Mediterranean region of Turkey in 1994–1997. In total, 25 parasitoid species belonging to Aphelinidae, Encyrtidae, and Eulophidae (Hymenoptera) were reared from 21 different scale hosts. On crop plants, mainly citrus and peach, 13 parasitoids from eleven Coccoidea hosts were determined while 14 parasitoid species were obtained from twelve scale insects on non-cultivated plants. Seven parasitoid species are new records for the Turkish insect fauna. Only one of them was found on citrus, while the other six species were sampled in non-cultivated areas. The most common parasitoids encountered were Aphytis melinus DeBach, Encarsia berlesei (Howard) (Aphelinidae), comperiella bifasciata Howard (Encyrtidae), and Metaphycus flavus (Howard) (Eulophidae) in cultivated areas and Coccophagus lycimnia (Walker) (Aphelinidae) in non-cultivated areas. All other parasitoids species were obtained only from a few scale insects hosts. In der vorliegenden Arbeit wurde die Parasitoiden-Fauna der Coccoidea in landwirtschaftlich genutzten und nicht genutzten Gebieten der östlichen Mittelmeer-Region der Türkei in der Zeit von 1994–1997 untersucht. Insgesamt konnten 25 Parasitoiden-Arten aus den Familien Aphelinidae, Encyrtidae und Eulophidae (Hymenoptera) aus 21 verschiedenen Schildlaus-Wirten gezogen werden. Von den Kulturpflanzen, vor allem von Zitrus und Pfirsich, wurden 13 Parasitoide aus 11 Coccoidea-Wirten gewonnen, während 14 Parasitoiden-Arten aus 12 Schildlaus-Wirten von den Wildpflanzen stammten. Bei sieben Parasitoiden-Arten handelt es sich um Neubeschreibungen der türkischen Insektenfauna. Nur eine von diesen wurde auf Zitrus beobachtet, während die anderen sechs Arten aus nicht bewirtschafteten Gebieten stammten. Die geläufigsten der ermittelten Parasitoiden-Arten waren Aphytis melinus DeBach, Encarsia berlesei (Howard) (Aphelinidae), Comperiella bifasciata Howard (Encyrtidae) sowie Metaphycus flavus (Howard) (Eulophidae) auf den bewirtschafteten und Coccophagus lycimnia (Walker) (Aphelinidae) auf den nicht bewirtschafteten Flächen. Alle anderen Parasitoiden-Arten wurden auf nur wenigen Schildlaus-Wirten beobachtet.

Inventaire des parasitoides d’ Eldana saccharina Walker Pyralidae , Galeriinae , foreur de tiges de la canne a sucre en Cote d’Ivoire
2018Co-Authors: K.d. Kouame, A.j. Gnago, A.t. Agneroh, K.c. Kouassi, K.s. Doh, G Seelavarn, H.j. Dove, B.m. Boua, B.i.c. PeneAbstract:Eldana saccharina W., ravageur majeur de la canne a sucre en Afrique a cause d’importants degâts depassant les 6 % en Cote d’Ivoire dans les perimetres sucriers de Ferke de 2015 a 2017, avec des pics de 30 a 40 %. L’etude vise a inventorier les parasitoides du foreur. Des oeufs, larves et chrysalides de foreurs ont ete collectees a Ferke 1 et eleves au laboratoire. Le niveau des populations a ete determine par les taux d’entre-noeuds et de cannes attaques. Les resultats ont permis de determiner deux especes de Lepidopteres : E. saccharina (98,5 %) et Sesamia calamistis Hampson (1,5 %). Le taux de parasitisme des larves et chrysalides etait faible (7,7 %). Les parasitoides oophages sont des Aphelinidae. La mouche Tachinidae, Sturmiopsis parasitica et une espece de Chloropidae parasitent les larves et Psilochalsis sp. (Chalcidoidae) parasite les larves et nymphes. Les Aphelinidae ont ete identifies pour la premiere fois comme parasitoides oophages des foreurs de la canne. Une augmentation des populations du foreur a ete observee avec un pic de Juin a Juillet. La lutte biologique contre ce ravageur par la production en masse des auxiliaires est une alternative durable aux methodes chimiques, a envisager. Mots cles: Canne a sucre ; Eldana saccharina ; Parasitoides ; Lutte biologique English Title: Inventory of parasitoids of Eldana saccharina Walker, Pyralidae , Galeriinae , sugarcane stemborer in Cote d’Ivoire English Abstract Eldana saccharina W. is the major pest of sugar cane in Africa. It causes significant damage in Cote d’Ivoire where infestations in the sugar perimeters are strongly resurgent and the 2015-2017 harvest seasons showed a high rate of infestations exceeding the threshold of 6 % and peaks of 30 to 40 %. The study aims to inventory the parasitoids of the driller. Eggs, larvae and chrysalis of drillers were collected at Ferke 1 and raised in the laboratory. The level of the populations was determined through the rates of internodes and canes attacked. Two species of Lepidoptera were identified : E. saccharina (98.5 %) and Sesamia calamistis Hampson (1.5 %). The rate of parasitism of larvae and pupae was low (7.7 %). The oophagous parasitoids are Aphelinidae. Sturmiopsis parasitica (Tachinidae) and a species of Chloropidae parasitize the larvae and Psilochalsis sp. (Chalcidoidae) parasitizes larvae and nymphs. The family of Aphelinidae has been identified for the first time as oophagous parasitoids of stem borers. The study showed an increase in borer populations with a peak from June to July. Biological control of this pest by the mass production of parasitoid, a sustainable alternative to chemical methods, could be initiate in Cote d’Ivoire.
