Ciclo de vida, hábitos y enemigos naturales de Neoleucinodes elegantalis (Guenée, 1854), (Lepidoptera: pyralidae), pasador del fruto del lulo Solanum quitoense Lam. en el Valle del... by Muñoz L. Edilberto, De la Cruz L. Jaime, Serrano P. Alberto, Pulido Jaime I.

“…Oviposition in seven days reached an average at 93 eggs. Parthenogenesis was not observed. Natural enemies: Encyrtidae, possibly Copidosoma, parasiting egg and hatching in larvae at the last instar; 2.500 observed showed 1.6% parasitism Tachinidae 0.08% parasitism 527 pupae were observed showing 0.38% parasitism for Ichneumonidae. 400 pupae were observed showing 55% parasitism for Beauveria. …”

Molecular characterization of aedes albopictus (diptera:culicidae) from hot spot dengue-infested areas / Siti Nazrina Camalxaman, Prof Madya Rodziah Ismail and Dr. Nazri Che Dom by Camalxaman, Siti Nazrina, Ismail, Rodziah, Che Dom, Nazri

“…The potential of Wolbachia to manipulate various functional systems of its hosts affects several aspects of host biology, physiology, immunity, ecology and evolution as well as reproductive properties including feminization, parthenogenesis, male killing and most commonly, cytoplasmic incompatibility (CI) (Werren, 1997). …”

Ixodidas brasileiros e de alguns paizes limitrophes by Henrique de Beaurepaire Aragão

“…The author gives a detailed report upon the parthenogenesis of A. rotundatum (A. agamum) that he first described in 1912 and gives also many references to other species of brazilian ticks, to teratological forms etc. …”

Wolbachia infection in Argentinean populations of Anastrepha fraterculus sp1: preliminary evidence of sex ratio distortion by one of two strains by Claudia Alejandra Conte, Diego Fernando Segura, Fabian Horacio Milla, Antonios Augustinos, Jorge Luis Cladera, Kostas Bourtzis, Silvia Beatriz Lanzavecchia

“…The presence of these maternally inherited bacteria is associated with modifications of host fitness, including a variety of reproductive abnormalities, such as cytoplasmic incompatibility, thelytokous parthenogenesis, host feminization and male-killing. Wolbachia has attracted much interest for its role in biological, ecological and evolutionary processes as well as for its potential use in novel and environmentally-friendly strategies for the control of insect pests and disease vectors including a major agricultural pest, the South American fruit fly, Anastrepha fraterculus Wiedemann (Diptera: Tephritidae). …”

A Plant-Specific TGS1 Homolog Influences Gametophyte Development in Sexual Tetraploid Paspalum notatum Ovules by Carolina Colono, Juan Pablo A. Ortiz, Hugo R. Permingeat, Eduardo Daniel Souza Canada, Lorena A. Siena, Nicolás Spoto, Florencia Galdeano, Francisco Espinoza, Olivier Leblanc, Silvina C. Pessino

“…Aposporous apomictic plants form clonal maternal seeds by inducing the emergence of non-reduced (2n) embryo sacs in the ovule nucellus and the development of embryos by parthenogenesis. In previous work, we reported a plant-specific TRIMETHYLGUANOSINE SYNTHASE 1 (TGS1) gene (PN_TGS1-like) showing expression levels positively correlated with sexuality rates in facultative apomictic Paspalum notatum. …”

Supplementation of SDF1 during Pig Oocyte In Vitro Maturation Improves Subsequent Embryo Development by Huaxing Zhao, Yazheng Dong, Yuxing Zhang, Xiao Wu, Xianjun Zhang, Yalin Liang, Yanan Li, Fang Zeng, Junsong Shi, Rong Zhou, Linjun Hong, Gengyuan Cai, Zhenfang Wu, Zicong Li

“…We found that the IVM medium containing 20 ng/mL SDF1 improved the maturation rate of pig oocytes, as well as the cleavage rate and blastocyst rate of embryos generated by somatic cell nuclear transfer, in vitro fertilization, and parthenogenesis. Supplementation of 20 ng/mL SDF1 during IVM decreased the ROS level, increased the mitochondrial membrane potential, and altered the expression of apoptosis-related genes in the pig oocytes. …”

Ciclo de vida, hábitos y enemigos naturales de Liriomyza sativae blanchard (Diptera: agromyzidae), minador del fríjol by Cruz L. Jaime de la, Cruz R. Ana M. de la, Cardona J. César

“…Adults can mate several times with the same or different pair. There is not parthenogenesis in this species. Two parasites of L. sativae were found: Opius sp, a larval parasite that emerges from the pupa and Diglyphus begini, a larval parasite. …”

Parasitism and predation of the planthopper Tagosodes orizicolus (Homoptera: Delphacidae) by a dryinid parasitoid in Costa Rica by Floria Mora-Kepfer, Ana Mercedes Espinoza

“…Our results indicate that female dryinids prefer to oviposit in female T. orizicolus nymphs and prey on males. Reproduction by parthenogenesis, acceleration of the development in an insectary with controlled conditions and eficiency of H. hernandezae as a parasitoid and predator indicate that this dryinid is an effective biological control agent of T. orizicolus. …”

Effects of exposure to dmso in vitrification solution on cytotoxicity and in vitro viability of immature bovine oocyte. by H., Hajarian, Haron, Abd Wahid, Othman, Abas Mazni, Yusoff, Rosnina, M., Daliri, M., Dashtizad

“…Based on previous studies for vitrification of oocytes, it has been shown that short term exposure to DMSO during vitrification could improve the maturation rate and cause not spontaneous parthenogenesis (Isachenko et al., 2006). In addition, it was reported that DMSO in freezing media caused disassembly of microfilaments and chromosomal abnormalities in mouse oocytes (Vincent et al., 1990). …”

Maternal Cytokines CXCL12, VEGFA, and WNT5A Promote Porcine Oocyte Maturation via MAPK Activation and Canonical WNT Inhibition by Xin Liu, Xin Liu, Yuchen Hao, Yuchen Hao, Zhekun Li, Zhekun Li, Jilong Zhou, Jilong Zhou, Hongmei Zhu, Guowei Bu, Guowei Bu, Zhiting Liu, Zhiting Liu, Xudong Hou, Xia Zhang, Yi-Liang Miao, Yi-Liang Miao, Yi-Liang Miao

“…More importantly, these maternal cytokines improve the developmental potential of matured oocytes by parthenogenesis, fertilization, and cloning, as their blastocyst formation efficiencies and total cell numbers are increased. …”

The Very Early Embryo & Its Moral Significance by Andrew J Prunty

“…He argues that an individual gamete does not have the potential to develop into a human being on its own accord as there has yet to be a case of spontaneous human parthenogenesis. However, just as a sperm cannot develop into an embryo independently, an embryo cannot develop into a human independently either; in the context of both, they are in need of ‘another half’ to successfully develop: a sperm cannot develop into an embryo without an egg, and an embryo cannot mature into a human without a suitable environment to grow and develop. …”
