Chemical interaction between undamaged plants [PDF]

open access: yes, 2011
Most research on plant–plant chemical interactions has focussed on events following herbivore or pathogen attack. However, undamaged plants also interact chemically as a natural facet of their behaviour, and this may have consequences for insects that ...

Bioecology and Domiciliation of the Alkali Bee, Hoplonomia westwoodi (Gribodo, 1894) (Hymenoptera: Halictidae: Nomiinae) from India

open access: yesSociobiology, 2022
We describe here nesting biology of Hoplonomia westwoodi, a common ground nesting solitary bee in India. A typical nest consisted of a straight main tunnel with the cells arranged horizontally at the end. Number of cells per nest ranged from 2 to 4 (x̄ =

Fungal sex receptors recalibrated to detect host plants [PDF]

open access: yes, 2015
Secreted peroxidases are well-known components of damage-induced defense responses in plants. A recent study in Nature ( Turrà et al., 2015) has revealed that these enzymes can inadvertently serve as reporters of wounded sites and constitute an “Achilles

Effects of volatiles from Maruca vitrata larvae and caterpillar-infested flowers of their host plant Vigna unguiculata on the foraging behavior of the parasitoid Apanteles taragamae [PDF]

open access: yes, 2010
The parasitoid wasp Apanteles taragamae is a promising candidate for the biological control of the legume pod borer Maruca vitrata, which recently has been introduced into Benin. The effects of volatiles from cowpea and peabush flowers and Maruca vitrata

The molecular basis of host specialization in bean pathovars of Pseudomonas syringae [PDF]

open access: yes, 2012
Biotrophic phytopathogens are typically limited to their adapted host range. In recent decades, investigations have teased apart the general molecular basis of intraspecific variation for innate immunity of plants, typically involving receptor ...

Flight, feeding and reproductive behavior of Phyllophaga cuyabana (Moser) (Coleoptera: Melolonthidae) adults Comportamento de vôo, de alimentação e de reprodução de adultos de Phyllophaga cuyabana (Moser) (Coleoptera: Melolonthidae)

open access: yesPesquisa Agropecuária Brasileira, 2003
Phyllophaga cuyabana is a univoltine species and its development occurs completely underground. Its control by conventional methods, such as chemical and biological insecticides, is difficult, so it is important to understand its dispersion, reproduction,

Prey and Non-prey Arthropods Sharing a Host Plant: Effects on Induced Volatile Emission and Predator Attraction [PDF]

open access: yes, 2008
It is well established that plants infested with a single herbivore species can attract specific natural enemies through the emission of herbivore-induced volatiles.
