We chose five easily propagated garden plants previously shown to be attractive to mosquitoes, ants or other insects and tested them for attractiveness to Culex pipiens and Aedes aegypti. Long term imbibition was tested by survival on each plant species.

Larval Food-plants and Nectar Flowers
2008Butterfly caterpillars feed on the leaves or sometimes flower-parts of green plants and the adult insects visit flowers for nectar, and in a few instances pollen. Whilst most butterflies are not very particular about their sources of nectar, taking it where and when available, their selection of plant species on which to lay their eggs is specialized ...

Postsecretory Hydrolysis of Nectar Sucrose and Specialization in Ant/Plant Mutualism
Science, 2005Obligate Acacia ant plants house mutualistic ants as a defense mechanism and provide them with extrafloral nectar (EFN). Ant/plant mutualisms are widespread, but little is known about the biochemical basis of their species specificity.

The effects of insect visitors on nectar constituents in temperate plants
Oecologia, 1980The floral nectar of angiosperms is primarily a solution of simple sugars, but contains detectable amounts of other solutes, particularly amino acids. These have been regarded as diagnostic, for phylogenetic and taxonomic purposes, and their mean concentrations may be significant in relation to the pollination syndrome of a plant species.

Effects of nectar-robbing on plant reproduction and evolution
Frontiers of Biology in China, 2007The relationship between plant and pollinator is considered as the mutualism because plant benefits from the pollinator’s transport of male gametes and pollinator benefits from plant’s reward. Nectar robbers are frequently described as cheaters in the plant-pollinator mutualism, because it is assumed that they obtain a reward (nectar) without providing

Can selection to escape nectar thieving force plants to portion nectar in many flowers?
Acta Oecologica, 1999There are several hypotheses which try to explain why particular plants produce just the number of flowers that they do. These hypotheses include: compromises between the attraction of pollinators and avoiding self-pollination by geitonogamy; optimal nectar production as a result of diminishing gains of nectar production; opportunity for selective ...

Optimal nectar production in a hummingbird pollinated plant
Theoretical Population Biology, 1981Abstract It is hypothesized that the average rate of nectar production per flower for a population of plants is such than an individual plant which possesses this rate has maximum fitness (i.e., is optimal). This basic hypothesis is used to develop predictions concerning nectar production in scarlet gilia ( Ipomopsis aggregata ), a hummingbird ...

Plant–pollinator interaction model with separate pollen and nectar dynamics
Journal of Theoretical BiologyThe mutualism between plants and pollinators involves the exchange between plant resources and pollen dispersal services among con-specific plants. Since many pollinators are generalist foragers, the quality of pollination is compromised by inter-specific pollen transfer (IPT).

A model for nectar secretion in animal-pollinated plants
Evolutionary Ecology, 1993A game theoretic model was developed for nectar secretion in animal-pollinated plants in order to examine how the total amount of resources allocated to flowers affects the spread of nectarless plants. It was assumed that pollinators concentrate on patches whose nectar rewards are relatively large compared to other patches and if pollinators visit a ...
