Kinematic and force patterns of interaction of a link caterpillar of a transport machine with the ground [PDF]

open access: yesFME Transactions, 2023
This article proposes a mathematical model of a caterpillar track's force and kinematic interaction with the ground during movement. The presence of a positive displacement of caterpillar tracks was proved even in the absence of slipping.

Comparison of nestling diet between first and second broods of great tits Parus major in urban and forest habitats

open access: yesAnimal Biodiversity and Conservation, 2023
To understand why early broods tend to be more successful than late broods we investigated the nestling diet and reproductive success of great tit pairs that had both a first and a second brood in the same breeding season.

Cloning, characterization, and heterologous expression of a candidate Hirudin gene from the salivary gland transcriptome of Hirudo nipponia

open access: yesScientific Reports, 2023
Hirudin is a pharmacologically active substance in leeches with potent blood anticoagulation properties. Although recombinant hirudin production isolated from Hirudo medicinalis Linnaeus and Hirudinaria manillensis Lesson is known, to our knowledge, this

Development of a Caterpillar-Type Walker for the Elderly People

open access: yesApplied Sciences, 2021
A walker assists elderly people with age-related reduced walking ability and helps to improve stability and balance ability. However, if the general-type walker (GTW) is used on an uneven, obstacle, or sloped terrain, it may cause excessive muscle use ...

note on the rediscovery of the Redspot butterfly Zesius chrysomallus Hübner, 1819 (Lepidoptera: Lycaenidae: Theclinae) from Uttar Pradesh State, with a new larval host plant record for India

open access: yesRevista Chilena de Entomología, 2021
Zesius chrysomallus Hübner, 1819 – The Redspot – is rediscovered from Varanasi area in Uttar Pradesh State after 108 years. Cordia dichotoma G. Forst, 1786 of Boraginaceae family is new addition to list of larval host plants from India.

Pomegranate moth is the most dangerous pest of pomegranate bushes in the conditions of the Western part of Azerbaijan [PDF]

open access: yesRomanian Journal of Horticulture, 2021
The pomegranate moth (Euzophera punicacella Mocre.) is the most widespread and well-known pest of pomegranate bushes in the western part of Azerbaijan. The loss of yield from the pomegranate moth (Euzophera punicacella Mocre.) in the pomegranate orchards

Sphingid caterpillars conspicuous patches do not function as distractive marks or warning against predators

open access: yesEcology and Evolution, 2023
To avoid predation by visual predators, caterpillars can be cryptic to decrease detectability or aposematic to warn predators of potential unpalatability.

Spatial separation of the cyanogenic β-glucosidase ZfBGD2 and cyanogenic glucosides in the haemolymph of Zygaena larvae facilitates cyanide release [PDF]

open access: yesRoyal Society Open Science, 2017
Low molecular weight compounds are typically used by insects and plants for defence against predators. They are often stored as inactive β-glucosides and kept separate from activating β-glucosidases.

Distinct Arabidopsis Responses to Two Generalist Caterpillar Species Differing in Host Breadth

open access: yesPhytoFrontiers, 2021
In general, caterpillar herbivores with a narrow host preference (specialists) have evolved mechanisms to circumvent specific plant defenses. In contrast, caterpillars with a broader host range (generalists) may manipulate phytohormone pathways common to

Maize resistance to insect herbivory is enhanced by silencing expression of genes for jasmonate‐isoleucine degradation using sugarcane mosaic virus

open access: yesPlant Direct, 2022
Previously, sugarcane mosaic virus (SCMV) was developed as a vector for transient expression of heterologous genes in Zea mays (maize). Here, we show that SCMV can also be applied for virus‐induced gene silencing (VIGS) of endogenous maize genes ...
