Though few data document the causes of qualitative and quantitative variation in cucurbitacins among Cucurbita species, the spatial and temporal patterns of cucurbitacin distribution within plants and between species are not likely to be fortuitous or satisfactorily explained by defense or non-defense hypotheses alone. Some interspecific differences in cucurbitacin concentration correlate with xeric and mesic characteristics of cucurbit habitats and support the hypothesis that the production of… 

Divergence of defensive cucurbitacins in independent Cucurbita pepo domestication events leads to differences in specialist herbivore preference.

Results in Cucurbita pepo support the testable hypothesis that breeding for plant resistance to insects involves targeting genes for regulation and transport of defensive metabolites, in addition to core biosynthesis genes.

Effects of age, sex, and dietary history on response to cucurbitacin in Acalymma vittatum

The chrysomelid Acalymma vittatum is stenophagous, subsisting almost entirely on plants in the Cucurbitaceae, which generally contain cucurbitacins. Cucurbitacins are extremely bitter tetracyclic

Fate of Male-derived Cucurbitacins in Spotted Cucumber Beetle Females

Using the spotted cucumber beetle, Diabrotica undecimpunctata howardi, as a model species, we begin an examination of the role of dietary cucurbitacins, the bitter tetracyclic triterpenes produced by

An ecological cost of plant defence: attractiveness of bitter cucumber plants to natural enemies of herbivores

Novel evidence is provided for an ecological trade-off between direct and indirect plant defence mediated by the effects of cucurbitacins on predator fecundity and potentially by the production of volatile compounds that may be repellent to predators.

Notes on Lagenaria and Cucurbita (Cucurbitaceae) -review and new contributions

An overview of the genus with special consideration of seed coat characteristics is presented and the Vinous Styrian Oil-pumpkin, with thin-coated seeds, is treated in respect of its cultivars, history, breeding and importance in Styria.

Squash Varieties Domesticated for Different Purposes Differ in Chemical and Physical Defense Against Leaf and Root Herbivores

Plant domestication often reduces plant defenses by selection on chemical and physical defense traits. Thus, it is expected that herbivorous insects perform better on crop varieties than on their

Resistance and tolerance to herbivory changes with inbreeding and ontogeny in a wild gourd (Cucurbitaceae).

The effects of inbreeding significantly reduced resistance to herbivory and, independently of beetle damage, reproductive output, and additive genetic variation for both resistance and tolerance that varies with ontogeny was found.

Mechanisms of Resistance to Insect Herbivores in Isolated Breeding Lineages of Cucurbita pepo

Divergences in constitutive and induced resistance measured by growth of generalist caterpillars and leaf traits are identified, indicating that deterrent cultivar-specific volatiles appear to provide general resistance to insect herbivores.

Bacterial communities of herbivores and pollinators that have co-evolved Cucurbita spp

High variability in the composition of bacterial communities in squash bees and beetles collected from different geographic locations and different time points throughout a growing season is found, which suggests these insects may be exposed to similar environmental microbial sources while foraging on the same genus of host plants, and that similar microbial taxa may aid in digestion of Cucurbita plant material.

Gourds and squashes (Cucurbita spp.) adapted to megafaunal extinction and ecological anachronism through domestication

It is hypothesized that Holocene ecological shifts and megafaunal extinctions severely impacted wild Cucurbita, whereas their domestic counterparts adapted to changing conditions via symbiosis with human cultivators, and anthropogenic landscapes provided favorable growth habitats and willing dispersal partners in the wake of ecological upheaval.



Cucurbitacins as kairomones for diabroticite beetles.

The results demonstrate a coevolutionary association between the Cucurbitaceae and the Luperini, during which the intensely bitter and toxic Cucs that arose to repel herbivores and protect the plants from attack became specific kairomone feeding stimulants for the beetles.

Cucurbitacins : Plant-derived defense compounds for diabroticites (Coleoptera: Chrysomelidae).

Four species of diabroticites with different host specificities are shown for the first time to sequester cucurbitacins, and the mantids failed to learn to avoid any of the beetle species despite adverse effects associated with ingestion, i.e., uncoordination, regurgitation, etc.

Relative Attractance of Spotted Cucumber Beetle to Fruits of Fifteen Species of Cucurbitaceae

The technique of exposing fruits to D. undecimpunctata howardi has potential as a bioassay to screen cucurbitacins in the fruits of other species and can be useful in population assessment and in luring the beetle to an insecticide or to an adhesive.

Western Corn Rootworm Adult and Spotted Cucumber Beetle Associations with Cucurbita and Cucurbitacins

The spotted cucumber beetle (SCB), D. undecimpunctata howardi Barber, exhibited similar aggregation and feeding responses to wild mesophytic Cucurbita species with high cucurbitacin foliage but showed a more consistent feeding preference for cultivated species than the WCR.

Squash Beetle Feeding Behavior: An Adaptation against Induced Cucurbit Defenses

This study tests the hypothesis that feeding behavior in the herbivorous coccinellid Epilachna borealis is an effective adaptation for avoiding facultative chemical defenses in its cucurbit host plants and shows that E. borealis trenching behavior blocks, at least temporarily, the translocation of cucur Bitacin defenses to feeding sites, thus preserving the palatability and quality of food resources for beetles.

Diabroticite Beetle Responses to Cucurbitacin Kairomones in Cucurbita Hybrids1

Two hybrid cucurbits were produced that combined the genetic production of cucurbitacins as found in the wild bitter gourds, Cucurbita andreana Naud and C. texana Gray, with the high fruit yields

Offensive-Defensive Interactions between Herbivores and Plants: Their Relevance in Herbivore Population Dynamics and Ecological Theory

It is suggested that interactions within and among species of herbivores are better understood in terms of interference and facilitation than in termsof competition.

Influence of Cucurbitacin Content in Cotyledons of Cucurbitaceae Cultivars upon Feeding Behavior of Diabroticina Beetles (Coleoptera: Chrysomelidae)

A new analytical procedure for cucurbitacins using high-pressure liquid chromatography is described, which is of value in selecting resistant varieties of Cucurbitaceae cultivars for integrated pest management programs.
