Insect biological control: a global perspective
The intentional use of biological control agents to manage arthropod pests dates back to as early as 304 AD, when Chinese farmers used weaver ants to manage citrus pests. Over time, biological control has evolved into ...
Differentiation of two Bathyplectes species, B. anurus and B. curculionis, parasitoids of the Alfalfa weevil (Hypera postica) in Spain
The alfalfa weevil Hypera postica Gyllenhal (Coleoptera: Curculionidae) is one of the most destructive alfalfa pests in the world, resulting in substantial economic losses. However, the amount of damage can be reduced by ...
Linking root length and surface area to yield: variety-specific root plasticity in winter wheat across contrasting European environments
Understanding the relationship of root traits and crop performance under varying environmental conditions facilitates the exploitation of root characteristics in breeding and variety testing to maintain crop yields under ...
Base and upper temperature thresholds to support the calculation of growing degree days aiming at their use with the FAO56rev crop coefficients curve: A review
Growing Degree Days (GDD) are a fundamental tool for supporting crop and water management, estimating crop development and growth and, in particular, defining the crop coefficient curve, thus computing crop evapotranspiration ...
Use of a Digital Twin for Water Efficient Management in a Processing Tomato Commercial Farm
The increasing pressure on water resources caused by agricultural intensification, the rising food demand and climate change requires new irrigation strategies that improve the sustainability and efficiency of agricultural ...
Influenza Aviar: características de la enfermedad, situación actual y perspectivas futuras
La influenza aviar (InAv) o "gripe aviar" es una enfermedad viral aguda que afecta mayoritariamente las aves domesticas y esta causada por virus de influenza tipo A. A lo largo de las ultimas decadas, el numero y extension ...
Spectroscopic Analysis of Proximal Leaves as a Method for Studying Nectarine Ripening
Traditional methods for fruit quality assessment are labor-intensive, destructive, and result in the loss of marketable produce. Spectroscopy, especially near-infrared (NIR) and mid-infrared (MIR), has helped in the ...
Identification of Gambierdiscus species from La Réunion and evaluation of toxicity and toxin profile
Five different species of Gambierdiscus have been identified in La Réunion (G. belizeanus, G. balechii, G. pacificus, G. silvae and G. ribotype 2) by morphological observations in Scanning Electron Microscopy (SEM) and ...
Bivariate and multivariate analyses of allometric growth in larvae of farmed meagre (Argyrosomus regius): an integrated approach to define growth stages and ontogenetic transitions
Fish larval rearing represents a critical stage due to the extreme fragility of larvae, small size, and specific nutritional needs during rapid growth. Successful larviculture requires understanding ontogenetic changes to ...
Efficacy of a Novel PCV2d and Mycoplasma hyopneumoniae Combined Vaccine in Piglets with High and Low Levels of PCV2 Maternally Derived Antibodies at Vaccination
Background/Objectives: Maternally derived antibody (MDA) levels of porcine circovirus 2 (PCV2) may eventually interfere with humoral response and vaccination efficacy. This study aimed to evaluate the efficacy of a ...
Spatial and seasonal performance of Blattisocius tarsalis in stored grain environments
In large-scale grain storage facilities, various pests can infest stored grain causing significant damage. The predatory mite Blattisocius tarsalis has shown robust dispersal abilities in controlled environments, along ...
Comparison of LC-MS methods for the quantitation of ciguatoxins in fish – A collaborative study
Ciguatoxins (CTXs) are marine biotoxins that can contaminate seafood and if consumed can result in ciguatera poisoning (CP). The analysis of CTXs is challenging, as they occur in complex tissue matrices, cause CP symptoms ...
First description of Vibrio ostreicida as putative causal agent of disease in Mediterranean mussel (Mytilus galloprovincialis) and development of a PCR protocol for its rapid diagnosis
In April 2022, mussels (Mytilus galloprovincialis) cultivated in the Ebro River delta (Spain) were affected by a mortality episode, involving 25 % of individuals, observed at a water temperature of 18 °C. Mussel samples ...
Increasing levels of fishmeal replacement by defatted black soldier fly larvae meal reduced growth performance without affecting fillet quality in largemouth bass (Micropterus salmoides)
A 90-day feeding trial was conducted to evaluate the effects of replacing dietary fishmeal (FM) with defatted black soldier fly larvae meal (BSFL) on the growth performance and fillet quality of largemouth bass (Micropterus ...
The role of Fragaria vesca homolog of a (Z)-3:(E)-2-hexenal isomerase in the development of green-leafy fruit aroma
The green leaf volatiles (Z)-3-hexenal and (E)-2-hexenal are key components of the characteristic strawberry aroma, an important determinant of consumer preferences. Green leaf volatiles (GLVs) are C6 compounds that impart ...
Morpho-physiological digestive features of genetically closely related sympatric lacustrine whitefish forms with different feeding habits
The effect of different feeding habits on gut morphology and digestive function has been intensively studied during the last decades but sympatric closely related fishes are relatively rare objects of such studies. In the ...
Two volatiles from anthracnose-infected blueberries trigger electrophysiological and aversive behavioral responses in Drosophila suzukii (Diptera: Drosophilidae)
Native to Southeast Asia, the spotted-wing drosophila (Drosophila suzukii Matsumura) is an economically important invasive pest of thin-skinned fruits such as raspberries, blueberries, and strawberries worldwide. To reduce ...
Primers resultats de la xarxa de noves varietats de favó
Enguany fa 4 anys que es va iniciar la xarxa de varietats comercials de favó. Durant aquest temps s’ha vist que AXEL, PROTHABON 101 i VINICIUS han mostrat un bon comportament productiu, sense diferències significatives ...
Helmintosporiosi reticular de l'ordi a Catalunya: un repte present i futur
L'ordi és un dels cereals més conreats a Catalunya, fonamental tant per a la producció de pinso com per a la indústria maltera. No obstant això, com qualsevol cultiu, s'enfronta a diverses amenaces que en poden comprometre ...
