Root herbivory reduces growth and survival of the shoot feeding specialist Pieris rapae on Brassica nigra

Pieris rapae – a nectar feeding butterfly: Composition of the cuticle of the proboscis

The Genome of Pieris rapae Granulovirus.

Pieris rapae granulovirus (PrGV) can infect and kill larvae of Pieris rapae, a worldwide and important pest of mustard family crops. The PrGV genome consists of 108,592 bp, is AT rich (66.8%), and is most structurally and organizationally similar to the Choristoneura occidentalis granulovirus genome. Of the predicted 120 open reading frames (ORFs), 32 genes specifically occurred in GVs, includi...

The Interaction between Root Herbivory and Competitive Ability of Native and Invasive-Range Populations of Brassica nigra

The evolution of increased competitive ability (EICA) hypothesis predicts that escape from intense herbivore damage may enable invasive plants to evolve higher competitive ability in the invasive range. Below-ground root herbivory can have a strong impact on plant performance, and invasive plants often compete with multiple species simultaneously, but experimental approaches in which EICA predi...

Experimental analysis of the liquid-feeding mechanism of the butterfly Pieris rapae.

The butterfly Pieirs rapae drinks liquid using a long proboscis. A high pressure gradient is induced in the proboscis when cibarial pump muscles contract. However, liquid feeding through the long proboscis poses a disadvantage of high flow resistance. Hence, butterflies may possess special features to compensate for this disadvantage and succeed in foraging. The main objective of this study is ...
