Definition of the number of instars, description of the second instar andredescription of the last instar and pupa of Pantophthalmus kerteszianus(Enderlein, 1914) (Diptera: Pantophthalmidae)

open access: yesBoletim do Museu Paraense Emílio Goeldi - Ciências Naturais
O número total de ínstares larvais de Pantophthalmus kerteszianus foi determinado através de estudos morfológicos e biométricos. O segundo ínstar larval de P. kerteszianus é descrito, o último ínstar larval e a pupa são redescritos. As larvas foram coletadas em árvores de paricá (Schizolobium parahyba var. amazonicum) no município de Paragominas, Pará,

From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

open access: yesOikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

Optimizing UV-A Solar-Powered Lights to Enhance Lures for Codling Moth, Cydia pomonella L. (Lepidoptera: Tortricidae)

open access: yesInsects
Field trials were conducted to define several parameters associated with adding LEDs to monitoring traps for codling moth (CM), Cydia pomonella (L.), using both a sex pheromone lure (PH1X) and a non-pheromone lure (CM4K).

Larval predation on different instars in blowfly populations

open access: yesBrazilian Archives of Biology and Technology, 2004
During its larval stage, Chrysomya albiceps (Diptera: Calliphoridae) is a facultative predator on other blowflies. In this study, we evaluated the predation by third instar larvae of C.

Hexagenia limbata early instar transcriptome assemblies

open access: yes, 2021
These two transcriptomes were assembled from the same set of reads (NCBI SRA accession SRX6489924), which were sequenced from a pooled sample of approximately 100 μl of whole-body nymphs, most 1st instar and some 2nd instar. The transcriptomes differ in

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Larval instar determination of the pea and bean weevil Sitona lineatus L. (Coleoptera: Curculionidae)

open access: yes, 1984
Head-capsule measurements on larvae of Sitona lineatus (L.) collected on beans (Vicia faba) in southern England in 1980 showed that there were 5 larval instars.

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

open access: yesPest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was
