Abstract:

Cocoa (Theobroma cacao L.) is an entomophilous plant which is need insects for pollination. Pollinator insects increase cocoa’s fruit set. The aim of this research were to study diversity of pollinator insects, visiting activity of fly, Forcipomyia (Diptera), and fruit set of cocoa. Observation of pollinator insects was conducted by scan sampling method. Visiting activity of Forcipomyia were observed based on duration visit per flower, number of flowers visited per minute, and duration of activity on flowers. Pollen load on body of Forcipomyia were measured. Pollination effectiveness of insect

Abstract:Nocturnally foraging insects may be supplementary pollinators to chiropterophilous plant species when bats are scarce. Given that insects are much smaller than bats, they may be more effective at transferring pollen for plant species with similar stamen and pistil lengths, such as the ‘Monthong’ durian cultivar. The present study clarifies the role of insects in pollinating the ‘Monthong’ cultivar by examining the floral biology, conducting pollination treatments on 19 trees and observing floral visitors in southern Thailand.

The objective of this study is to ascertain the pollinator contribution to cowpea production, as well as to determine the pollination type of the `BR3-Tracuateua' cultivar.

Perhaps the most conspicuous of associations between insects and plants is pollination.

It was shown through the use of bagging and caging experiments, controlled hand-pollination and emasculation of flowers, that the wind plays little role in cashew pollination and that cashew is self-fertile, although only pollen from the large stamen, either male or hermaphrodite-derived, can effect pollination.

Agriculture in Australia is highly dependent on insect pollination, in particular from the introduced western honeybee, Apis mellifera. Most agricultural pollination is provided as an unpaid service by feral A. mellifera and native insects. A smaller proportion of agricultural pollination is provided as a paid service by beekeepers. Insect pollination is threatened by misuse of insecticides and the loss of remnant vegetation, but most potently by the likelihood that the honeybee mite, Varroa destructor, will enter the country.

Abstract:

Studies on the pollination biology of Eriocaulaceae are scarce although particularly interesting because of its inclusion in the Poales, a predominantly wind-pollinated order. The pollination biology of Syngonanthus elegans (Bong.) Ruhland was studied during two annual flowering periods to test the hypothesis that insect pollination was its primary pollination system. A field study was carried out, including observations of the morphology and biology of the flowers, insect visits and pollinator behaviour. We also evaluated seed set, seed germination and seedling development for different polli

Insects are viewed from the harmful perspectives and aimed at killing them through several means including indiscriminate use of deadly chemicals. If good judgment made keeping views on sustainable crop production, natural balance and pollution free environment, they are important component of the ecosystem and their beneficial aspects are immense. One of them is that insects provide pollination service to plants. The study showed that over 50 species of insects visited flowers of 17 different species of selected crops during flowering periods.

Abstract:

English ivy (Hedera helix) is an important resource for wildlife in rural and urban ecosystems. It provides pollen and nectar for flower-visiting insects during autumn and fruits for frugivores during winter and spring. A requirement of insect pollination for fruit set in ivy implies that recent declines in pollinator populations can threaten food supply for frugivores. This study investigated the link between pollination services and the quantity and quality of fruit produced in ivy, and how that could in turn influence frugivore feeding choices, in a mixed woodland and an urban garden habita

Pollination in oil palm is generally carried out by insects. The beetle Elaeidobius kamerunicus is one of the effective pollinating insects for oil palm. This beetle breeds well on male flowers, this beetle can also reach female flowers located in the inner bunch, so this condition causes more perfect pollination. This study aims to determine the population of oil palm pollinating insects E. kamerunicus at several ages of oil palm plants which will be associated with environmental factors and ways of oil palm cultivation, both application of pesticides and fertilizers in Rasau Jaya District, K

Although specialist pollination systems are often thought to be the outcome of selection, wide evidence exists for generalization within plant-pollinator interactions. We studied the pollination system and reproductive success of Calluna vulgaris (L.) Hull over 3 years in an Upper Ardennes site in Belgium. A wide variety of insect visitors was recorded including Hymenoptera, Diptera, and Lepidoptera. Relative abundance of families and species of visitors varied markedly among years except for bees.

Abstract:

Tribulus terrestris is a herbaceous weed capable of growing throughout the year in many habitats. It is hermaphroditic, protogynous, and self-pollinating, although it is also insect-pollinated. The insects involved in pollination use their flowers as a potential forage source by displaying fidelity during the wet season when profuse flowering occurs. The functional traits relating to sexual reproduction such as autonomous selfing, insect-pollination, polychory, and C4 photosynthetic pathway are quite advantageous for the plant to grow as a successful weed in different habitats, prominently in

Abstract:

Abstract Insect pollination is essential to many unmanaged and agricultural systems and as such is a key element in food production. However, floral scents that pollinating insects rely on to locate host plants may be altered by atmospheric oxidants, such as ozone, potentially making these cues less attractive or unrecognizable to foraging insects and decreasing pollinator efficacy. We demonstrate that levels of tropospheric ozone commonly found in many rural areas are sufficient to disrupt the innate attraction of the tobacco hawkmoth Manduca sexta to the odor of one of its preferred flowers,

Based on four seasons of field studies, we show an unexpected correlation between pollination and the phases of the moon in one of our studied species, Ephedra foeminea . It is pollinated by dipterans and lepidopterans, most of them nocturnal, and its pollination coincides with the full moon of July. This may be adaptive in two ways. Many nocturnal in

Bumblebees were very efficient pollinators of Sl Lycopersicon species, averaging only 5 s to pollinate one flower and fly to the next.
