SummaryPieris rapae and P. brassicae feed on the same host plants and have synchronized seasons. P. brassicae, whose larvae are twice the size of P. rapae, lays eggs in clusters of 40–100 eggs whereas P. rapae lays single eggs. In this paper we examine how egg clustering may be advantageous for P. brassicae. The larval development of each species was studied, and found not to differ significantly. P. brassicae larvae were observed to migrate from their host plant after defoliating it. A… 

Assessment of effects of Bt‐oilseed rape on large white butterfly (Pieris brassicae) in natural habitats

TLDR
A population model showed that larval survival is increased with amount of food and reduced with the frequency of transgenic specimens, number of host plants needed for completing larval development, and number of egg‐laying butterflies.

Egg Laying of Cabbage White Butterfly (Pieris brassicae) on Arabidopsis thaliana Affects Subsequent Performance of the Larvae

TLDR
It is demonstrated that oviposition does increase A. thaliana resistance to feeding by subsequently hatching larvae, but this cannot be attributed simply to changes in glucosinolate content.

Plant Quantity Affects Development and Survival of a Gregarious Insect Herbivore and Its Endoparasitoid Wasp

TLDR
The results, in comparison with previous studies, reveal that quantitative constraints are far more important that qualitative constraints on the performance of gregarious insect herbivores and their g Regarious parasitoids in nature.

Autecology of the endemic Crimson Rose butterfly Pachliopta hector (Lepidoptera : Rhopalocera : Papilionidae)

TLDR
It is established that Pachliopta hector Linn, endemic to Sri Lanka and south India, is on wings throughout the year with a higher density during August/September/October/November and also during AprilJune.

Costs and Benefits of Egg Clustering in Pieris brassicae

TLDR
The presence of caterpillars was found to have an inhibitory effect on plant growth and a model is developed to show how the degree of inhibition of plant growth due to larval feeding can affect the extent to which more food is available to a group of larvae feeding onTwo plants sequentially than to two groups, each of half the size, feeding on two plants simultaneously.

SEQUENTIAL RAPID ADAPTATION OF INDIGENOUS PARASITOID WASPS TO THE INVASIVE BUTTERFLY PIERIS BRASSICAE

TLDR
The invasion of an exotic host species may provide the opportunity to observe the dynamics of changing interspecific interactions among parasitoids belonging to different trophic levels, and changes in host preference may result from differential suitability of the two host types.

Autecology of the endemic Crimson Rose butterfly Pachliopta hector (Lepidoptera : Rhopalocera : Papilionidae)

The study including field observations on the distribution of eggs, larvae, purpae on the larval host Aristolochia indica and the laboratory study on the success rate of eggs, larvae and pupae

Study on the biology and consumption potential of Common Rose Pachliopta aristolochiae aristolochiae F (Lepidoptera: Papilionidae) on Aristolochia tagala

TLDR
Field observations and laboratory study established that Pachliopta aristolochiae aristolchiae endemic to Southeast Asia is on the wings throughout the year with a higher density during the wet season (May-October).

Tolerance of Brassica nigra to Pieris brassicae herbivory

TLDR
Results demonstrate that B. nigra tolerates folivory from Pieris brassicae through compensation, suggesting a connection between their belowground zone of influence and ability to regain biomass.

Consequences of ‘no-choice, fixed time’ reciprocal host plant switches on nutrition and gut serine protease gene expression in Pieris brassicae L. (Lepidoptera: Pieridae)

TLDR
These snapshots reflected contrasts in physiological and developmental plasticity of P. brassicae larvae to nutritional challenges from wide dietary switches in the short term and the prominent role of gut serine proteases in rapid dietary adaptations.

The adaptiveness of searching and host selection behaviour in Pieris rapae (L.)

TLDR
The adaptive significance of host preferences and searching behaviour in Vancouver and Canberra populations of the cabbage butterfly Pieris rapae is evaluated in a manner consistent with the observed behavioural differences.

How discriminating are cabbage butterflies

TLDR
C cabbage butterflies lay most eggs on the larger, older leaves of plants, though the oldest are sometimes avoided, and discrimination against less acceptable varieties is just as strong when plants of preferred varieties are not present, as when both varieties occur in the same patch.

Host plants, nectar source plants, and habitat selection of males and females of Anthocharis cardamines (Lepidoptera)

TLDR
The foraging strategies of males and females were similar, mainly serving to minimize time spent searching for nectar source plants to maximize time expenditure on search for mates and host plants, respectively, but females visited a larger number of different plant species for feeding than did males, presumably as a result of their more generalized habitat preferences.

Egg-laying Habits of Lepidoptera in Relation to Available Food

TLDR
The following field studies were undertaken to supply some information on the contribution of the adult's behaviour to the degree of survival in larval populations is unknown.

THE SEARCH FOR RESOURCES BY CABBAGE BUTTERFLIES (PIERIS RAPAE): ECOLOGICAL CONSEQUENCES AND ADAPTIVE SIGNIFICANCE OF MARKOVIAN MOVEMENTS IN A PATCHY ENVIRONMENT'

TLDR
A simulation of the flight behavior of ovipositing P. rapae results in the placement of more eggs on isolated hosts to demonstrate the effectiveness of egg spreading in averaging out observed variations in larval survivorship and to estimate the potential advantages accrued by egg spreading.

Egg Deposition Patterns in Butterflies: Why Do Some Species Cluster Their Eggs Rather Than Deposit Them Singly?

  • N. Stamp
  • Environmental Science, Biology
    The American Naturalist
  • 1980
TLDR
It is suggested that the occurrence of butterfly species which deposit eggs in clusters is more common than the literature indicates and that data on egg deposition patterns in natural populations of nymphalids in North America, in particular for Phyciodes, Chlosyne, Euphydryas, and Nymphalis species, would support this conclusion.

MOVEMENT PATTERNS AND EGG DISTRIBUTION IN CABBAGE BUTTERFLIES

TLDR
Butterfly density tends to vary inversely with host density, despite aggregative behaviour identical to that which, in predator-prey systems, leads to a direct correlation between the densities of searcher and resource.

Effects of Disparlure and Egg Mass Size on Parasitism by the Gypsy Moth Egg Parasite, Ooencyrtus kuwanai

TLDR
Seven plots in Monroe CO., Pa., with a general gypsy moth, Lymantria dispar (L.), infestation were treated with disparlure, and the application of disparlures had no effect on either size of egg mass or percent parasitism.

Group feeding as a strategy for exploiting food resources in the burnet moth Pryeria sinica

TLDR
Pryeria sinica (Zygaenidae) larvae feed on young and growing leaves of Euonymus japonicus in groups in groups to hypothesize that larval aggregation is an adaptation for the economical utilization of limited food resources.

Assessment of egg load by Pieris brassicae (Lepidoptera: Pieridae)

TLDR
It is found that several cues enable the butterfly to ‘assess’ the egg load present on a plant or leaf, and at the appropriate moment switch to the previously less acceptable species, and overloading is avoided.
