The role of the wild plants in relation to the conservation of the Indonesian insectpollinators was studied at several areas of Java. Three of direct observationmethods were applied: study of biodiversity and observation on the wild flowersand the insect pollinators as well, and the behaviour of the insects. The flowersof wild plants were relatively smaller and paler in colour, however they were moreattractive to insect pollinators than cultivated plants. Flowering time of the wildplants was mostly during wet seasons, contrary to that of the cultivated plantswhich was mostly during dry seasons. Our observation indicated that these wildplants are the food resources of insect pollinators during wet seasons. Observationdata support the importance of wild plants to supply food to insect pollinatorsduring wet seasons. Management of wild and cultivated plant environments isnecessary to conserve insect pollinators.

The Subject

The aim of the paper was to determinate the importance of pollinating insects for food security in Poland. To assess this, there was estimated crop production without pollinators. The information published by the Institute of Horticulture and the Central Statistical Office was used as well as the literature on the subject. The results of the study indicate that insect pollinators play a key role in fruit production, absence of pollinators may result in a crop yield reduction about 80%. In terms of physical availability of food, Polish food security will be preserved even in the absence of insect pollinators. However, at the level of economic availability, food security may not be preserved without such pollinators, in particular in terms of fruit and food security associated with the consumption of properly balanced rations.

Transpirational Water Loss

Floral humidity, an area of elevated humidity in the headspace of flowers, has been detected across angiosperms and may function as a pollinator cue for insect pollinators. It is believed floral humidity is produced predominantly through a combination of evaporation of both liquid nectar and transpirational water loss from the flower. However, the role of transpiration in floral humidity generation has not been tested and is largely inferred by continued humidity production when nectar is removed from flowers. Understanding the extent that transpiration contributes to floral humidity has important implications for understanding the function of floral humidity. We test whether transpiration contributes to the floral humidity generation of two species previously identified to produce elevated floral humidity, Calystegia silvatica and Eschscholzia californica. Floral humidity production of flowers that underwent an antitranspirant treatment - petrolatum gel which blocks transpiration from treated tissues - is compared to flowers that did not receive such treatments. Gel treatments reduced floral humidity production to approximately a third of that produced by untreated flowers in C. silvatica, and half of that in E. californica. This confirms, the previously untested, inferences that transpiration has a large contribution to floral humidity generation and that this contribution may vary between species.

Essential Input

Pollination is a critical link in the functioning of ecosystems, and it improves the yield of crops. Insect pollination is an essential input in the production of crops grown worldwide. Of the approximately 300 commercial crops about 84% are insect pollinated. Honeybees are responsible for 70-80% of insect pollination. This indicated how much honeybees are the most efficient insect pollinators of cultivated crops and wild flora in agricultural systems. The main reason is that honeybees are abundant and widespread everywhere. They have well developed mechanism of communication to exploit their environment. The value of additional yields obtained by pollination service rendered by honeybees is 15-20 times more than the value of all hive products put together. Studies conducted in Ethiopia have also proven the role of honeybee pollination in improving the yield and quality of some crops such as Malus sylvestris (apple), Allium cepa (red onion), Guizotia abyssinica (niger) and Vicia faba (faba bean). The yield increment was varied from 33.5-84% among the above crops due to honeybee pollination. However, unwise pesticide applications become the main problem for some crops in Ethiopia. This is due to, low level understanding of the value of pollination on the yield of agricultural crops. Therefore, attention should be given for the legal protection of honeybees and other insect pollinators; especially, protecting the honeybees from pesticide poisoning, developing pollinators’ conservation policy, the idea of crop pollination should be included in national crop production strategic plan and awareness creation should be given to the society about the value of crop pollination.

Bumblebees are one among the anthophilous form and play a significant role in the pollination of major agricultural crops like medicinal, aromatic, ornamental and various other horticultural plants. They are abundant and mostly confined to flowers present in the temperate, alpine and arctic climates of the northern continents. The bumblebees are considered as most important pollinators and are mainly responsible for the conservation of high altitude vegetation germplasm where other insect pollinators are very much limited. They are more successful pollinators and can visit large number of flowers per minute than other bees and are perfect for picking up and transferring appreciable amount of compatible pollen to flowers and thus perform buzz pollination. It is quite evident that the population of bumblebee is gradually declining throughout the globe for the last 7 decades due to agricultural intensification, habitat loss, deforestation, overgrazing, pesticide poisoning and climate change. The present paper addresses this issue on the basis of literature survey.
