Simple Summary Chinese MeiShan pigs make up one of the oldest Chinese pig breeds. Compared with Large White pigs, MeiShans are hyper-productive and prolific, however, the expression and function of circular RNAs (circRNAs) in these two breeds of pig are not yet fully understood. We performed RNA-seq analysis of porcine ovaries from three MeiShan so...

The present study was conducted to analyze the mRNA expression of the BMP/SMAD signaling and steroidogenesis associated genes in the granulosa cells (GCs) of newly developed Booroola homozygous carrier GMM (FecBBB ) and non-carrier GMM (FecB++ ) ewes through qRT-PCR. Results showed that the expression of BMP2 (P
Ooencyrtus lucidus Triapitsyn & Ganjisaffar (Hymenoptera: Encyrtidae) was recently recovered from fresh sentinel eggs of Bagrada hilaris (Burmeister) (Hemiptera: Pentatomidae) in California. In the present study, life history traits of O. lucidus were studied at 26 ± 0.5 °C, 40 ± 10 % RH, and a photoperiod of 14 L: 10 D hours. Results showed that 9...

Due to ethical issues associated with the use of blood for mosquito laboratory experiments, an artificial diet that supports the production of eggs and larvae is highly desirable. We report the development of an artificial diet using direct feeding on protein-rich sugar solution (PRSS) as an alternative to whole blood and evaluated its effects on s...

Abstract—Radiation effects on reproduction have been studied in root voles from areas with increased contents of heavy natural radionuclides (HNRs). To assess reproductive parameters in a population exposed to radiation over many generations, two experiments have been performed at an interval of 25 years (in 1984 and 2009). The observed intensifica...

AbstractSpawning flocks of rainbow smelt Osmerus dentex, in an anadromous migration in the Amur River were represented by individuals of length 15–25 cm at ages 3–5, among which males predominated (1 : 2). Histologic analysis shows that rainbow smelt is an iteroparous species with determinate fecundity, group-synchronous ovary organization and tota...
The pine wood nematode (PWN) Bursaphelenchus xylophilus is the pathogen that causes pine wilt disease (PWD), a devastating forest disease. PWN-associated bacteria may play a role in PWD. However, little is known about the endo-bacteria in PWN. We analyzed the diversity of endo-bacteria in nine isolates of PWNs from Pinus massoniana Lamb. in nine ep...
Background and Aim: The Watish sheep is a strain of desert sheep of smaller size compared to other desert sheep ecotypes, and there is anecdotal evidence that it is endowed with high litter size. The present study was designed for screening for polymorphisms in the known fecundity genes (bone morphogenetic protein receptor type 1B A

Four Beauveria bassiana and three Metarhizium brunneum isolates were evaluated, as soil drenches, against Spodoptera littoralis prepupae. Treatment efficacy was determined by assessing total mortality during development from prepupae through to pupae and adults; mortality and sub-lethal effects on reproduction were also quantified for adults emergi...

The invasive harlequin ladybird Harmonia axyridis is a textbook example of polymorphism and polyphenism as the temperature during egg development determines the frequency of melanic morphs and the number and size of black spots in nonmelanic morphs. Recent concepts in evolutionary biology suggest that epigenetic mechanisms can translate environment...
