Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

open access: yesEntomologia 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.

Amendment of Potting Soil With Black Soldier Fly Byproducts Affects Fungus Gnat Development

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The study's three experiments were conducted in accordance with the development stages of fungus gnats, with adults emerging from the four treatment substrates and being caught on sticky cards as a common indicator. The treatments were formed from peat‐free potting soil, either pure or supplemented with combinations of byproducts from black soldier fly

Nematode Management in Residential Lawns

open access: yesEDIS, 2017
Plant-parasitic nematodes are among the least understood and most difficult pests to manage on turfgrass in Florida. They are very small, and most can only be seen with the aid of a microscope.

Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段

open access: yesEcological Entomology, EarlyView.
The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

Bioactive forage and phytotherapy to cure and control endo-parasite diseases in sheep and goat farming systems – a review of current scientific knowledge [PDF]

open access: yes, 2007
Infestation with gastro-intestinal nematodes (GIN) in small ruminants can cause severe economic losses and endanger animal welfare. The development of organic farming systems, the increased public awareness for drug residues in agricultural products and ...

Introduction to Plant-Parasitic Nematodes; Modes of Parasitism

open access: yes, 2011
Plant-parasitic nematodes are pests of agricultural crops and cause considerable economic loss and, especially in developing countries, adverse social impact. They exhibit a variety of parasitic modes, with the endoparasitic cyst and root-knot nematodes attracting the most research interest.

Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).

Curtisia dentata (Cornaceae) leaf extracts and isolated compounds inhibit motility of parasitic and free-living nematodes

open access: yesOnderstepoort Journal of Veterinary Research, 2009
Haemonchus contortus and Trichostrongylus colubriformis are among the most important parasitic nematodes of small ruminants. Caenorhabditis elegans, a free-living nematode, is used as a model for evaluating anthelmintic activity of a variety of test ...

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and
