Seasonal Growth of Waterhyacinth in the Sacramento/San Joaquin Delta, California [PDF]

, 2005
Waterhyacinth ( Eichhornia crassipes (Mart.) Solms), is a serious problem in the Sacramento/San Joaquin Delta, California. There is little published information on its phenology or seasonal growth in this system. Waterhyacinths were sampled at 2 to

Epizootiology of the Fungal Pathogen, \u3ci\u3eZoophthora Phytonomi\u3c/i\u3e (Zygomycetes: Entomophthorales) in Field Populations of Alfalfa Weevil (Coleoptera: Curculionidae) Larvae in Illinois [PDF]

, 2017
The influence of the fungal pathogen, Zoophthora phytonomi, on larvae of the alfalfa weevil, Hypera postica, was studied in three alfalfa fields in Illinois. Disease epizootics occurred in all three fields and disease onset was ob- served within a fairly

Methods and Principles for Interpreting the Phenology of Crop Pests

Illinois Natural History Survey Bulletin, 1928
In the present state of affairs, this paper proposes primarily to call attention to a method of defining the relations of plant diseases to climate and weather; but it intends, also, to make additional suggestions which may be useful to entomologists (the latter having used the method to a limited extent) and to point out some of the fundamental ...

Functional Invertebrate Prey Groups Reflect Dietary Responses to Phenology and Farming Activity and Pest Control Services in Three Sympatric Species of Aerially Foraging Insectivorous Birds

PLoS ONE, 2014
Farming activity severely impacts the invertebrate food resources of farmland birds, with direct mortality to populations of above-ground arthropods thorough mechanical damage during crop harvests.

Biodiversity science is improved when silent herbaria speak

PLANTS, PEOPLE, PLANET, EarlyView.
Herbaria in the Global South are critical yet underutilized resources for biodiversity science and often absent from international databases and research networks. We highlight the phenomenon of “silent herbaria” using Nigeria as a case study and quantify how these collections fill important gaps in global biodiversity knowledge.

Explainable olive grove and grapevine pest forecasting through machine learning-based classification and regression

Results in Engineering
Pests significantly impact agricultural productivity, making early detection crucial for maximizing yields. This paper explores the use of machine learning models to predict olive fly and red spider mite infestations in Andalusia.

Resilience through diversity: The potential of modelling species and variety interactions to enhance resilience of production systems

PLANTS, PEOPLE, PLANET, EarlyView.
Agricultural production systems in the global North combine monocultures of specialised varieties and breeds with external interventions and inputs. Increasing the diversity of varieties, breeds and species may increase the system's resilience to external pressures through beneficial interactions.

Population dynamics and flight phenology model of codling moth differ between commercial and abandoned apple orchard ecosystems

Frontiers in Physiology, 2016
Apple orchard management practices may affect development and phenology of arthropod pests, such as the codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), which is a serious internal fruit-feeding pest of apples worldwide.

Effects of climate change and crop planting structure on the abundance of cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae)

Ecology and Evolution, 2020
The interactions between plants and insects play an important role in ecosystems. Climate change and cropping patterns can affect herbivorous pest insect dynamics.

The effects of flower supplementation on pollinators and pollination along an urbanisation gradient

PLANTS, PEOPLE, PLANET, EarlyView.
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to
