Effects of Rearing Density on Growth, Adult Emergence and Survival in the Edible Cricket Gryllodes sigillatus

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Gryllodes sigillatus is an increasingly important species in edible insect production, yet the optimal rearing density for this species under commercial conditions remains poorly defined. This study evaluated the effects of five rearing densities (1.5, 2, 2.5, 3 and 4 mL of newly hatched nymphs, corresponding to approximately 0.144–0.385 ...

Better Control With More Food: Continuous Provision of Alternative Food Enhances Thrips Control by Predatory Mites

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The use of alternative food has become an integral component of biocontrol, allowing the introduction and establishment of predators into a crop before pest invasion and sustaining populations even when pest densities are low. The addition of alternative food also has a positive long‐term effect in decreasing the densities of the pest.

First Detailed Record of Jikradia olitoria (Hemiptera: Cicadellidae) in the Swiss Southern Alps and Evaluation of Its Current Potential as a Vector of 16SrV‐Phytoplasmas

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Jikradia olitoria Say is a Nearctic leafhopper that was recently reported in several European countries. Given its role as the vector of phytoplasmas associated with Grapevine Yellows diseases (GYD) in its native range, its presence in European vineyard agroecosystems could represent an important phytosanitary risk.

First Record of Larval Parasitism in Disonycha glabrata (F.) (Coleoptera: Chrysomelidae) by Myiopharus ancilla (Walker) (Diptera: Tachinidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The amaranth flea beetle, Disonycha glabrata (F.), is a major pest of amaranth crops (Amaranthus spp.) in the United States. Despite its economic impact, its natural enemy complex remains poorly documented. In this study, we report the first record of larval parasitism in D. glabrata by the tachinid fly Myiopharus ancilla (Walker).

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

open access: yesMedical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Integrative revision of the Australian carrion‐breeding Calliphorinae (Diptera: Calliphoridae): Revision of the Calliphora stygia‐ and ochracea‐groups

open access: yesMedical and Veterinary Entomology, EarlyView.
The Australian carrion‐breeding Calliphorinae are revised using an integrative approach combining morphology and mitogenomics. A new taxonomic key, morphological images and verified mitogenomic data, including COX1 barcodes, are provided to support the identification of species.

Leaf trichomes affect caterpillar feeding in an instar-specific manner [PDF]

open access: yesCommunicative and Integrative Biology, 2018
Leaf trichomes play well-established roles in defense against insect herbivores, both as a physical barrier that impedes herbivore movement and by mediating chemical defenses.

Soldier Production Strategy in Lower Termites: From Young Instars or Old Instars?

Journal of Theoretical Biology, 2002
We constructed a mathematical model to explain from which instars soldiers should be produced to maximize the growth rate of a termite colony. The model is based on the demography of the lower termite's colony: many of them feed inside the nest. The model predicts the following: (1) When the colony is young (it still has enough food and needs a high ...

Ecology and Behavior of First Instar Larval Lepidoptera

Annual Review of Entomology, 2002
▪ Abstract  Neonate Lepidoptera are confronted with the daunting task of establishing themselves on a food plant. The factors relevant to this process need to be considered at spatial and temporal scales relevant to the larva and not the investigator.
