Entomologia Experimentalis et Applicata, EarlyView.Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

An Easy Method to Sample Headspace Pheromones in the Field
Ethology, EarlyView.Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Natural spawning of four Epinephelus species in the laboratory [PDF]
, 1996 Natural spawnings of four Epinephelus species reared in the laboratory were observed from 1987 to 1992. These species are: E. summana, E. caeruleopunctatus, E. macrospilus and E. fuscoguttatus.

Description of the immature stages of the planthopper Lacertinella australis (Hemiptera: Delphacidae) [PDF]
, 2014 The five immature stages of the planthopper Lacertinella australis(Remes Lenicov and Rossi Batiz) (Hemiptera: Delphacidae: Saccharosydnini) are described and illustrated. The main characters that al-lowed us to distinguish the various

Fisheries Management and Ecology, EarlyView.ABSTRACT Greenland halibut (Reinhardtius hippoglossoides) is a deep‐water flatfish which lives at temperatures of 1°C–4°C and produces large eggs (> 3 mm). The combination of low temperatures and large eggs has resulted in an unusual ovary development cycle, with vitellogenesis taking more than 1 year.

Evidence for prelocalization of cytoplasmic factors affecting gene activation in early embryogenesis [PDF]
, 1965 Differentiation begins early in embryogenesis as different genes become active in different cells. Within the closed system of the early embryo, equal genomes thus direct the creation of diverse cell types.

Journal of Applied Entomology, EarlyView.ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

Journal of Fish Biology, EarlyView.Abstract The plainfin midshipman (Porichthys notatus Girard, 1854) is a toadfish with two distinct reproductive male tactics: ‘guarder males’ and ‘sneaker males’. These two tactics are anatomically, physiologically and behaviourally distinct from one another at sexual maturity, but it remained unclear whether these two male types remain fixed or ...

Journal of Fish Biology, EarlyView.Abstract The European pilchard, Sardina pilchardus, is a key small pelagic fish sustaining Mediterranean ecosystems and fisheries. This study represents the first comprehensive biological and population dynamics assessment of the European pilchard by applying the length‐based spawning potential ratio (LB‐SPR) approach to S.
