Institut National de la Recherche Agronomique (INRA), Sorbonne Université, CNRS, IRD, UPEC, Université Paris Diderot, Institute of Ecology and Environmental Sciences of Paris, Paris and Versailles, France.

Phytophagous insects use volatile organic compounds (VOC) emitted by plants to orient towards their hosts. In lepidopteran pests, crop damages are caused by larval stages-the caterpillars-that feed extensively on leaves or other plant tissues. However, larval host plant choice has been poorly studied, and it is generally admitted that caterpillars feed on the plant where the female laid the eggs. Read More

Differential Impact of Herbivores from Three Feeding Guilds on Systemic Secondary Metabolite Induction, Phytohormone Levels and Plant-Mediated Herbivore Interactions.

J Chem Ecol 2018 Dec 29;44(12):1178-1189. Epub 2018 Sep 29.

Agroscope, Research Division Agroecology and Environment, Reckenholzstrasse 191, 8046, Zurich, Switzerland.

Phytochemical defense responses of plants are often herbivore-specific and can be affected by a herbivore's feeding mode. However, comprehensive studies documenting the impact of multiple herbivores from different feeding guilds on induced phytochemical responses in distal leaves and its consequences for plant-mediated herbivore interactions are limited and findings are inconsistent. We investigated how herbivory by leaf-chewing caterpillars, cell-content feeding spider mites and phloem-feeding aphids and whiteflies affect secondary metabolomes and phytohormone levels in youngest, non-damaged cotton leaves (distal leaves).

Leaf trichomes affect caterpillar feeding in an instar-specific manner.

Commun Integr Biol 2018 9;11(3):1-6. Epub 2018 Aug 9.

Department of Environmental Systems Science, ETH Zürich, Zürich, Switzerland.

Leaf trichomes play well-established roles in defense against insect herbivores, both as a physical barrier that impedes herbivore movement and by mediating chemical defenses. However, little work has examined how different trichome types influence herbivory by herbivores at different stages of development. We examined whether caterpillar instar and trichome type (glandular or non-glandular) affected the ability of the specialist herbivore caterpillar to initiate feeding on 11 Solanaceous species exhibiting variation in the density and type of leaf trichomes.

Jasmonic acid-induced plant defenses delay caterpillar developmental resistance to a baculovirus: Slow-growth, high-mortality hypothesis in plant-insect-pathogen interactions.

J Invertebr Pathol 2018 Oct 3;158:16-23. Epub 2018 Sep 3.

Department of Entomology and Center for Chemical Ecology, Pennsylvania State University, University Park, PA 16802, USA.

Plants damaged by herbivore feeding can induce defensive responses that reduce herbivore growth. The slow-growth, high-mortality hypothesis postulates that these non-lethal plant defenses prolong the herbivore's period of susceptibility to natural enemies, such as predators and parasitoids. While many juvenile animals increase their disease resistance as they grow, direct tests of the slow-growth, high-mortality hypothesis in the context of plant-herbivore-pathogen interactions are lacking.

Departamento de Zoologia, Instituto de Ciências Biológicas, Universidade de Brasília, Brasília, DF, Brasil.

β diversity of herbivorous insects in the tropics is usually very high, and there is often strong dissimilarity in herbivore species composition across different spatial scales and different abiotic gradients. Similarly, turnover is high for trophic interactions between herbivorous insects and their host plants. Two factors have been proposed to explain temporal or spatial differences in trophic interactions: changes in species composition and temporal changes in the behavior of shared species. Read More

Many plants express induced defenses against herbivores through increasing the production of toxic secondary chemicals following damage. Phytochemical induction can directly or indirectly affect other organisms within the community. In tri-trophic systems, increased concentrations of plant toxins could be detrimental to plants if herbivores can sequester these toxins as protective chemicals for themselves. Read More

Enumeration of compact coalescent histories for matching gene trees and species trees.

J Math Biol 2018 Aug 16. Epub 2018 Aug 16.

Department of Biology, Stanford University, Stanford, CA, 94305, USA.

Compact coalescent histories are combinatorial structures that describe for a given gene tree G and species tree S possibilities for the numbers of coalescences of G that take place on the various branches of S. They have been introduced as a data structure for evaluating probabilities of gene tree topologies conditioning on species trees, reducing computation time compared to standard coalescent histories. When gene trees and species trees have a matching labeled topology [Formula: see text], the compact coalescent histories of t are encoded by particular integer labelings of the branches of t, each integer specifying the number of coalescent events of G present in a branch of S.

IRD c/o icipe, P.O. Box 30772-00100, Nairobi, Kenya.

Foraging parasitoids use chemical signals in host recognition and selection processes. Although, the volatiles play a relevant role in the localization by parasitoids of their hosts feeding on plants, the host identification process for acceptance occurs mainly during contact between the parasitoid and its host where host products related to feeding activities, fecal pellets and oral secretions, play a crucial role. The purpose of this study was to identify the nature of the contact kairomone(s) that mediate the acceptance for oviposition of the parasitoid Cotesia flavipes Cameron (Hymenoptera, Braconidae), which was released in Kenya in 1993 to control the invasive crambid Chilo partellus (Swinhoe).

Although the emergence of gel-free approaches has greatly enhanced proteomic studies, two-dimensional gel electrophoresis (2-DE) remains one of the most widely used proteomic techniques for its high resolving power, relatively low cost, robustness, and high resolution. Preparation of high-quality protein samples remains the key in high-quality 2-DE for proteomic analysis. Samples with high endogenous levels of interfering molecules, such as salts, nucleic acids, lipids, and polysaccharides, would yield a low-quality 2-DE gel and hinder the analysis. Read More

Nutrient and Chemical Analysis of Fruiting Bodies of a Cultivar of the Chinese Caterpillar Mushroom, Ophiocordyceps sinensis (Ascomycetes).

Int J Med Mushrooms 2018 ;20(5):459-469

Ligno Biotech Sdn Bhd, Seri Kembangan, Selangor, Malaysia.

A cultivar of fruiting bodies of Ophiocordyceps sinensis (FBOS; OCS02) was analyzed for nutrients, bioactive compounds, and heavy metal content to showcase its potential as a competitive, sustainable, and safe alternative to wild types and other cultivars. A previous 28-day subacute toxicity study showed that doses up to 1 g · kg-1 did not cause any adverse effects in Sprague-Dawley rats. The OCS02 cultivar contained large amounts of cordycepin, polysaccharides, and essential and semi-essential amino acids (0. Read More

Across Multiple Species, Phytochemical Diversity and Herbivore Diet Breadth Have Cascading Effects on Herbivore Immunity and Parasitism in a Tropical Model System.

Front Plant Sci 2018 11;9:656. Epub 2018 Jun 11.

Department of Biology, University of Nevada, Reno, Reno, NV, United States.

Terrestrial tri-trophic interactions account for a large part of biodiversity, with approximately 75% represented in plant-insect-parasitoid interactions. Herbivore diet breadth is an important factor mediating these tri-trophic interactions, as specialisation can influence how herbivore fitness is affected by plant traits. We investigated how phytochemistry, herbivore immunity, and herbivore diet breadth mediate plant-caterpillar-parasitoid interactions on the tropical plant genus (Piperaceae) at La Selva Biological station in Costa Rica and at Yanayacu Biological Station in Ecuador.

A Modified String Technique for Atraumatic Ring Removal.

J Emerg Med 2018 08 19;55(2):240-243. Epub 2018 Jun 19.

Department of Orthopaedic Surgery, Mayo Clinic, Rochester, Minnesota.

Background: We describe a modified string technique for ring removal from an edematous finger, a critical step in the initial treatment of a patient with upper-extremity trauma.

Technique: This technique involves multiple sutures looped around the ring to provide differential tension on the ring as it is advanced distally over a lubricated digit. With the use of an assistant, the ring can be advanced in caterpillar fashion without sliding back proximal when the direct pressure is released as a result of edema. Read More

Upper thermal limits differ among and within component species in a tritrophic host-parasitoid-hyperparasitoid system.

PLoS One 2018 12;13(6):e0198803. Epub 2018 Jun 12.

Department of Biology, Virginia Commonwealth University, Richmond, Virginia, United States of America.

Understanding how climate change affects host-parasite systems and predicting the consequences for ecosystems, economies, and human health has emerged as an important task for science and society. Some basic insight into this complex problem can be gained by comparing the thermal physiology of interacting host and parasite species. In this study, we compared upper thermal tolerance among three component species in a natural host-parasitoid-hyperparasitoid system from Virginia, USA. Read More
