Oviposition in the blood-sucking insect Rhodnius prolixus is modulated by host odors [PDF]

open access: yes, 2015
Background: Triatomine bugs are blood-sucking insects, vectors of Chagas disease. Despite their importance, their oviposition behavior has received relatively little attention. Some triatomines including Rhodnius prolixus stick their eggs to a substrate.

Coactivation of leg reflexes in the stick insect [PDF]

open access: yesBiological Cybernetics, 1992
Each leg of a standing stick insect acts as a height controller. The leg contains several joints. Most of these joints are known to be controlled by feedback loops which are the basis of resistance reflexes (review Bassler 1983). This leads to the question of whether the resistance reflex of the whole leg can be understood as a simple, vectorial sum of

Functionally different pads on the same foot allow control of attachment: stick insects have load-sensitive "heel" pads for friction and shear-sensitive "toe" pads for adhesion.

open access: yesPLoS ONE, 2013
Stick insects (Carausius morosus) have two distinct types of attachment pad per leg, tarsal "heel" pads (euplantulae) and a pre-tarsal "toe" pad (arolium). Here we show that these two pad types are specialised for fundamentally different functions.

The response of neotropical dragonflies (Insecta: Odonata) to local and regional abiotic factors in small streams of the Amazon [PDF]

open access: yes, 2019
Since the relative role of local and regional abiotic factors on the Odonata diversity in rainforest streams is still poorly understood, we evaluated the effects of these factors on adult Odonata (Insecta) from preserved and altered streams in the ...

When the going gets rough – studying the effect of surface roughness on the adhesive abilities of tree frogs [PDF]

open access: yes, 2016
Tree frogs need to adhere to surfaces of various roughnesses in their natural habitats; these include bark, leaves and rocks. Rough surfaces can alter the effectiveness of their toe pads, due to factors such as a change of real contact area and abrasion

The Common Stick Insect [PDF]

open access: yesNature, 1936
SINCE 1910, we have bred a continuous supply of the common stick insect (Carausius). These are lodged in a glass rectangular case 18½ in. × 9 in. × 15½ in. fitted with a movable glass front. Two glass vases holding ivy leaves in water furnish food and moisture for the insects.

Studies on neotropical Phasmatodea XXI: Sigaruphasma, a new genus of Hesperophasmatini Bradley & Galil, 1977, from Hispaniola with the descriptions of two new species (Phasmatodea: Cladomorphinae)

open access: yesNovitates Caribaea, 2020
The new Hesperophasmatini–genus Sigaruphasma gen. nov. from Hispaniola is described and illustrated. It is remarkable for violating several of the previously stated diagnostic features of the tribe Hesperophasmatini Bradley and Galil, 1977.

Assortative Mating By Diet In A Phenotypically Unimodal But Ecologically Variable Population Of Stickleback [PDF]

open access: yes, 2008
Speciation with gene flow may be driven by a combination of positive assortative mating and disruptive selection, particularly if selection and assortative mating act on the same trait, eliminating recombination between ecotype and mating type ...

Survival dynamics of stick insect and the impact of environmental factors on natural fungal infection during the rainy season

open access: yesFrontiers in Microbiology
Phasmatodea, commonly known as stick insects, are recognized as noteworthy pests globally, impacting agriculture and forest ecosystems. Among them, the outbreak of Ramulus mikado has emerged as a notable concern in East Asian forests.
