Insect Science, EarlyView.Larval development time, ADG, survival rate and substrate consumption were not negatively affected by the levels of mycotoxins contamination Larvae excreted most of the ingested DON and its derivatives through exuviae and frass The mycotoxin accumulation rates observed in larvae were always below the current legal limits for livestock feed Abstract ...

Spikelet Variation in Zea Mays L.
Annals of the Missouri Botanical Garden, 1952 In classifying the different varieties of Indian corn, Zea Mays, scientists have paid little attention to comparative floral morphology. Since the kernel is economically the most important part of the maize plant nearly all classifications have been based on its texture and morphology.

Insect Science, EarlyView.Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Iflaviruses in arthropods: when small is mighty
Insect Science, EarlyView.Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Methods in Ecology and Evolution, EarlyView.Abstract Measuring directional root placement is critical for understanding plant responses to their below‐ground environment, and particularly their competing neighbours. Directional root placement is commonly measured using image analysis of roots growing in transparent pots (rhizoboxes), where the length of the root system of the target plants is ...

Annals of Applied Biology, EarlyView.A short‐term flood, implemented in a field experiment with sprinkler irrigation in maize production systems, increased soil moisture levels and reduced autoclaved citrate extractable protein, an indicator of soil biological health that reflects organically bound soil nitrogen, and also corresponded to greater differential abundance of soil bacterial ...

Food without fire: Environmental and nutritional impacts from a solar stove field experiment
American Journal of Agricultural Economics, EarlyView.Abstract Over 80% of the population in rural Sub‐Saharan Africa relies on biomass cooking fuel, a substantial source of anthropogenic greenhouse gases. We use a field experiment in Zambia to investigate the impact of solar stoves on biomass fuel use and cooking habits.

Acta Zoologica, EarlyView.ABSTRACT Based on adult morphological characters, the more than 300 species of Alpheus were divided into seven informal species groups, but some groups are not supported by molecular data. The aim here was to describe the zoea I of Alpheus bouvieri, and to do a review of the larval descriptions available in the literature, analysing whether the ...
