Efficient solar energy storage is a key challenge in striving towards a sustainable future. For this reason, molecules capable of solar energy storage and release through valence isomerization, so-called Molecular Solar Thermal energy storage (MOST), have been investigated. Here, we evaluate the energy storage potential through the photoconversion of the dihydroazulene-vinylheptafulvene (DHA/VHF) photo-thermal couple. The robust nature of this system has been determined through multiple energy storage and release cycles at elevated temperatures in three different solvents...

Commercial Cydia pomonella granulovirus (CpGV) products have been successfully applied to control codling moth (CM) in organic and integrated fruit production for more than 30 years. Since 2005, resistance against the widely used isolate CpGV-M has been reported from different countries in Europe. The inheritance of this so-called type I resistance is dominant and linked to the Z chromosome. Recently, a second form (type II) of CpGV resistance in CM was reported from a field population (NRW-WE) in Germany. Type II resistance confers reduced susceptibility not only to CpGV-M but to most known CpGV isolates and it does not follow the previously described Z-linked inheritance of type I resistance...

Biotic stress by mass outbreaks of defoliating pest insects does not only affect tree performance by reducing its photosynthetic capacity, but also changes N cycling in the soil of forest ecosystems. However, how insect induced defoliation affects soil N fluxes and, in turn, tree N nutrition is not well-studied. In the present study, we quantified N input and output fluxes via dry matter input, throughfall, and soil leachates. Furthermore, we investigated the effects of mass insect herbivory on tree N acquisition (i...

Several herbivorous insects and plant-associated microorganisms control the phytohormonal balance, thus enabling them to successfully exploit the plant by inhibiting plant defences and withdrawing plant resources for their own benefit. The leaf-mining moth Phyllonorycter blancardella modifies the cytokinin (CK) profile of mined leaf-tissues, and the insect symbiotic bacteria Wolbachia is involved in the plant manipulation to the benefit of the insect host. To gain a deeper understanding into the possible origin and dynamics of CKs, we conducted an extensive characterization of CKs in larvae and in infected apple leaves...

Pheromone biosynthesis activating neuropeptide (PBAN) is a member of the pyrokinin (FXPRLamide) insect neuropeptides. Here, we report the cloning of the gene Ostnu-PBAN from the E and Z pheromone strains of the European corn borer (ECB), Ostrinia nubilalis (Lepidoptera: Crambidae), a major pest of maize. The Ostnu-PBAN genomic sequence is > 5 kb in length and consists of six exons. The deduced amino acid sequence revealed a 200-residue precursor protein including a signal peptide, a 24-amino acid (aa) diapause hormone, a 37-aa PBAN and three other FXPRLamide neuropeptides...

BACKGROUND: Intestinal fatty acid-binding protein (I-FABP) has been shown to be of high diagnostic value in patients with acute mesenteric ischemia. Whether these results can be reproduced in critically ill patients on the ICU was to be investigated. MATERIALS AND METHODS: I-FABP was measured in serum and urine of 43 critically ill patients in ICU when mesenteric ischemia was suspected. Bowel ischemia was confirmed in 21 patients (group 1). 22 patients who survived at least seven days without confirmation of ischemia were assigned to group 2...

Communication is an inherently interactive process that weaves together the fabric of both human and nonhuman primate societies. To investigate the properties of the primate brain during active social signaling, we recorded the responses of frontal cortex neurons as freely-moving marmosets engaged in conversational exchanges with a visually occluded Virtual Marmoset (VM). We found that small changes in firing rate (∼1Hz) occurred across a broadly distributed population of frontal cortex neurons when marmosets heard a conspecific vocalization, and that these changes corresponded to subjects' likelihood of producing or withholding a vocal reply...

PREMISE OF THE STUDY: The genus Hoya (Apocynaceae; Asclepiadoideae) is characterized by a set of complex floral characters unique among the asclepiads, but their role in pollination is poorly understood. Here, we report a new mechanism of asclepiad pollination in the wax plant Hoya carnosa: the pollinaria are transferred on the legs of medium or large settling moths. METHODS: Floral visitors and their behavior were observed on Amami-Oshima Island during 2013-2015, and the efficacy of different pollinators was determined by counting the pollinarium loads on different flower visitors...

The goal of this study was to develop effective and practical field sampling methods for quantifying aerial deposition of airborne conidia of Entomophaga maimaiga over space and time. This important fungal pathogen is a major cause of larval mortality in invasive gypsy moth (Lymantria dispar) populations in the United States. Airborne conidia of this pathogen are relatively large (similar in size to pollen) with unusual characteristics, requiring specialized methods for collection and quantification. Initially, dry sampling (settling of spores from the air onto a dry surface) was used to confirm the detectability of E...

Antimicrobial peptides (AMPs) are small-molecule peptides that play crucial roles in insect innate immune responses. To better understand the function of AMPs in Plutella xylostella, one of the main pests of cruciferous vegetables, three full-length cDNAs encoding moricins were cloned from Pl. xylostella. Two variants of the moricin named PxMor2 and PxMor3 were heterologously expressed and purified. A secondary structure analysis using circular dichroism demonstrated that the two peptides adopted an α-helical structure in the membrane-like environment, but in aqueous solution, they were present in random coiled conformation...

Most species of moths use a female-produced volatile sex pheromone, typically produced via de novo fatty acid synthesis in a specialized gland, for communication among mates. While de novo biosynthesis of pheromone (DNP) is rapid, suggesting transient precursor acids, substantial amounts of pheromone precursor (and other) acids are stored, predominantly in triacylglycerols in the pheromone gland. Whether these stored acids are converted to pheromone later or not has been the subject of some debate. Using a tracer/tracee approach, in which we fed female Heliothis virescens U-(13)C-glucose, we were able to distinguish two pools of pheromone, in which precursors were temporally separated (after and before feeding on labeled glucose): DNP synthesized from a mixed tracer/tracee acetyl CoA pool after feeding, and pheromone made from precursor acids primarily synthesized before feeding, which we call recycled precursor fat pheromone (RPP)...

The piercing fruit moth Oraesia emarginata is an economically significant pest; however, our understanding of its olfactory mechanisms in infestation is limited. The present study conducted antennal transcriptome analysis of olfactory genes using real-time quantitative reverse transcription PCR analysis (RT-qPCR). We identified a total of 104 candidate chemosensory genes from several gene families, including 35 olfactory receptors (ORs), 41 odorant-binding proteins, 20 chemosensory proteins, 6 ionotropic receptors, and 2 sensory neuron membrane proteins...

Hernán Mario Beccacece, Adriana Inés Zapata
Arctiini (Lepidoptera, Erebidae, Arctiinae) is the most speciose tribe of tiger moths. In this study, the taxonomy of some Neotropical species of this tribe is reviewed based on habitus and, in some cases, genitalia of type specimens. Lectotypes are designated for two names. Four new combinations are proposed: Agaraea sericeum (Zerny, 1931) comb. n., Biturix nigrostriata (Rothschild, 1909) comb. n., Carales fasciatus (Rothschild, 1909) comb. n. and Opharus pallida (Dognin, 1910) comb. n. Six new synonymies are proposed: Agaraea nigrotuberculata Bryk, 1953 (=Agaraea klagesi (Rothschild, 1909)), Opharus ochracea Joicey & Talbot, 1918 and Pelochyta fergusoni Watson & Goodger, 1986 (=Opharus pallida (Dognin, 1910)), Melese flavescens Joicey & Talbot, 1918 (=Melese paranensis Dognin, 1911), Leucanopsis infucata (Berg, 1882) (=Pareuchaetes aurata aurata (Butler, 1875)) and Tessellota pura Breyer, 1957 (=Tessellota cancellata (Burmeister, 1878))...

The almond moth, Cadra cautella (Walker) (Lepidoptera: Pyralidae), is a serious worldwide pest of dates and other crops, both in the field and in storage. Infestation by this pest significantly limits the sale and export of dates. Modified atmospheres, the temperature manipulations, are the best eco-friendly alternatives in stored product protection. We examined temperature regulation as an ecologically friendly method of pest management in stored food commodities, in particular, its effects on characteristics of C...
