Lethal effects of allyl isothiocyanate on the egg masses of flighted spongy moth complex Lymantria dispar japonica (Lepidoptera: Erebidae)

open access: yesPest Management Science, EarlyView.
This study showed that AITC substance was lethal effect to Lymantria dispar japonica egg mass, and our results show a significant decline in egg hatching rate with increasing AITC concentrations. Abstract BACKGROUND The flighted spongy moth complex (FSMC) lays egg masses not only on host plants but also various artificial structures, such as, cargo ...

Effects of competition and predation risk from a life history intraguild predator on individual specialisation

open access: yesJournal of Animal Ecology, EarlyView.
Individual niche specialisation is widespread within animal populations and can have important ecological consequences. Predation and competition are known drivers of individual specialisation, but their combined effects are unstudied. This mesocosm experiment shows that competition and predation from a single antagonist can have variable effects on ...

The pupae of Japanese Anopheles

open access: yesMedical Entomology and Zoology, 1959
Since M. Yamada (1936) made taxonomical descriptions about four kinds of pupae of Korean Anopheles, Takada (1949) made a brief description on the pupa of A. lindesaii japonicus, Mizukawa (1950) observed the external form of A. sine&s, Kaida (1951) compared of A. Zesteri pupa with that of A. sinensis, Asanuma & Nakagawa (1954) constructed the key to the

Long‐term population dynamics of western tent caterpillars: History, trends and causes of cycles

open access: yesJournal of Animal Ecology, EarlyView.
The length and in‐depth nature of this population study make it unique. It represents perhaps the most extensive monitoring of viral infection in a wild insect population. We have used laboratory and field experiments to test many hypotheses about mechanisms that potentially impact the dynamics of this cyclic species.

Pupa veintitrés

open access: yes, 2020
El constante cambio de espacios ha marcado mi vida, convirtiéndome en nómada de manera impuesta. Todo en mi vida se vuelve transitorio y desechable. Todo esto sucede debido a una marcada inestabilidad y a distintas experiencias poco agradables. Por todo esto se desarrolla en mi la resiliencia.

Foliar herbivory pushes plant individuals towards the periphery of a plant–floral visitor interaction network

open access: yesJournal of Ecology, EarlyView.
The authors demonstrate how the effects of herbivory on a key plant trait can cascade to shape the interactions between individual plants and their flower visitors and how the indirect effects between herbivores and pollinators can modulate the structure of interaction networks in terrestrial ecosystems.
