Effects of cold storage after cold acclimation on the fitness of Habrobracon hebetor (Hymenoptera: Braconidae).

Habrobracon hebetor (Say) (Hymenoptera: Braconidae) is a cosmopolitan, idiobiont, and gregarious ectoparasitoid, which can parasitize the larvae of several pyralid and noctuid moths. However, adult parasitoids require cold storage to ensure that adequate individuals are available when a pest outbreak occurs. To understand the effects of cold storage after acclimation on offspring fitness of H.

Transgenerational effects of multiple mating in Fabricius (Lepidoptera: Noctuidae).

Polyandrous mating can result in sexual conflict and/or promote the evolution of mating patterns. Does multiple mating by females support the genetic benefits hypothesis and can it be validated as an evolutionary strategy? If we are to decipher the consequences of sexual interactions and understand the interplay of sexual conflict and multiple generational benefits, the transgenerational effects need to be followed over multiple generations. We investigated the effects of three mating patterns, single mating, repeated mating, and multiple mating, on parental copulation behavior, and then identified the impact on the development, survival, and fecundity of the F and F generations.

Some species of the genus are very similar in morphological characteristics, so they are difficult to identify accurately. In this study, 12 mitochondrial genomes of species with similar morphological characteristics were first obtained through high-throughput sequencing, which featured a typical circular molecule of 15,034-15,988 bp in length.

Antimicrobial mexicanolide limonoids from the seeds of .

Three new mexicanolide limonoids were obtained from the 90% ethanol extract of the seeds of Their structures were elucidated as senegalenines AC () by analysing their 1D/2D NMR and MS spectroscopic analysis. In addition, the isolated limonoids were tested for antimicrobial potentials against 5 pathogenic microorganisms. Consequently, compounds exhibited antimicrobial activity against the tested Gram negative bacteria at the minimum inhibitory concentration values less than 40 μg/ml.

Host Deprivation Effects on the Functional Response and Parasitism Rate of Habrobracon hebetor (Hymenoptera: Braconidae) on Ephestia elutella (Lepidoptera: Pyralidae) in the Laboratory.

Habrobracon hebetor (Say) is an important biological control agent for lepidopteran pests of stored products. In this study, the age-specific functional response, paralysis rate, and parasitism rate of H. hebetor under different host deprivation treatments (PC: without host deprivation, used as the control, P1d: host deprivation, but the host was removed after 1 d contact, and PW: host deprivation from beginning) were evaluated at different larval densities (5, 10, 20, 40, and 80) of the Ephestia elutella (Hübner) at 28 ± 1°C, 75 ± 5% RH and 16:8 h L:D.

Outside-in catalytic graphitization method for synthesis of dispersible and uniform graphitic porous carbon nanospheres.

Common strategies to synthesize graphitic porous carbon nanospheres suffer from energy consumption, exorbitant cost and harsh condition, and lead to closed pore and polydisperse particles. The successful manipulation of adjustable graphitic skeleton, developed porosity, good monodispersity and dispersity of carbon nanospheres is essential to meet their structural varieties and practical applications. Herein, an outside-in catalytic graphitization method is reported to synthesize carbon nanospheres with abovementioned properties, which involves interfacial assembly between layered double hydroxides nanosheets and polymer nanospheres, in-situ generation of nickel nanoparticles, and outside-in catalytic graphitization.

Consuming Parasitized Aphids Alters the Life History and Decreases Predation Rate of Aphid Predator.

Intraguild predation interactions have substantial theoretical and practical implications for the dynamics of natural competitor populations used for biological control. Intraguild predation on parasitized aphids not only has a direct, negative effect on the parasitoid species, but it may indirectly influence the predator's development, survival, reproduction and predation rates. In this study, we used two-sex life table theory, life table parameters and predation rates of (Rondani) to compare when its populations fed on aphids ( Sulzer) (Hemiptera: Aphididae) that were either unparasitized or parasitized by (Ashmead) (Hymenoptera: Braconidae).

Structure-based virtual screening of influenza virus RNA polymerase inhibitors from natural compounds: Molecular dynamics simulation and MM-GBSA calculation.

The resistances of matrix protein 2 (M2) protein inhibitors and neuraminidase inhibitors for influenza virus have attracted much attention and there is an urgent need for new drug. The antiviral drugs that selectively act on RNA polymerase are less prone to resistance and possess fewer side effects on the patient. Therefore, there is increased interest in screening compounds that can inhibit influenza virus RNA polymerase.
