Insects and flowers are a partnership. Each insect group has evolved different sets of mouthparts to exploit the Gh. I Hassan food that flowers provide. From the insects' point of view collecting nectar or pollen is rather like fitting Sher-e-Kashmir University of a key into a lock; the mouthparts of each species can only exploit flowers of a certain size and shape.

It Technology, Shalimar, Jammu is definitely not a case of 'one size fits all'. While some insects are generalists and can exploit a wide and Kashmir-India range of flowers, others are specialists and are quite particular in their needs. In flowering plants, pollen grains germinate to form pollen tubes that transport male gametes (sperm cells) to the egg cell in the Bilal A Padder embryo sac during sexual reproduction.

Proposed Integrated Control of Zoonotic Plasmodium Knowlesi in Southeast Asia Using Themes of One Health
Tropical Medicine and Infectious Disease Review Proposed Integrated Control of Zoonotic Plasmodium knowlesi in Southeast Asia Using Themes of One Health Jessica Scott College of Public Health and Medical and Veterinary Sciences, Australian Institute of Tropical Health and Medicine, James Cook University, Townsville 4811, Australia; [email protected] Received: 25 September 2020; Accepted: 18 November 2020; Published: 20 November 2020 Abstract: Zoonotic malaria, Plasmodium knowlesi, threatens the global progression of malaria elimination. Southeast Asian regions are fronting increased zoonotic malaria rates despite the control measures currently implemented—conventional measures to control human-malaria neglect P. knowlesi’s residual transmission between the natural macaque host and vector. Initiatives to control P. knowlesi should adopt themes of the One Health approach, which details that the management of an infectious disease agent should be scrutinized at the human-animal-ecosystem interface. This review describes factors that have conceivably permitted the emergence and increased transmission rates of P. knowlesi to humans, from the understanding of genetic exchange events between subpopulations of P. knowlesi to the downstream effects of environmental disruption and simian and vector behavioral adaptations. These factors are considered to advise an integrative control strategy that aligns with the One Health approach. It is proposed that surveillance systems address the geographical distribution and transmission clusters of P. knowlesi and enforce ecological regulations that limit forest conversion and promote ecosystem regeneration. Furthermore, combining individual protective measures, mosquito-based feeding trapping tools and biocontrol strategies in synergy with current control methods may reduce mosquito population density or transmission capacity.

The Dominant Anopheles Vectors of Human Malaria in the Asia-Pacific
Sinka et al. Parasites & Vectors 2011, 4:89 http://www.parasitesandvectors.com/content/4/1/89 RESEARCH Open Access The dominant Anopheles vectors of human malaria in the Asia-Pacific region: occurrence data, distribution maps and bionomic précis Marianne E Sinka1*, Michael J Bangs2, Sylvie Manguin3, Theeraphap Chareonviriyaphap4, Anand P Patil1, William H Temperley1, Peter W Gething1, Iqbal RF Elyazar5, Caroline W Kabaria6, Ralph E Harbach7 and Simon I Hay1,6* Abstract Background: The final article in a series of three publications examining the global distribution of 41 dominant vector species (DVS) of malaria is presented here. The first publication examined the DVS from the Americas, with the second covering those species present in Africa, Europe and the Middle East. Here we discuss the 19 DVS of the Asian-Pacific region. This region experiences a high diversity of vector species, many occurring sympatrically, which, combined with the occurrence of a high number of species complexes and suspected species complexes, and behavioural plasticity of many of these major vectors, adds a level of entomological complexity not comparable elsewhere globally. To try and untangle the intricacy of the vectors of this region and to increase the effectiveness of vector control interventions, an understanding of the contemporary distribution of each species, combined with a synthesis of the current knowledge of their behaviour and ecology is needed. Results: Expert opinion (EO) range maps, created with the most up-to-date expert knowledge of each DVS distribution, were combined with a contemporary database of occurrence data and a suite of open access, environmental and climatic variables. -

Building on recent improvements in computational power and tracking technology, we have developed a versatile climate-controlled wind tunnel system, in which to study the effect of climate parameters, including temperature, precipitation, and elevated greenhouse gas levels, on odor-mediated behaviors in insects. To establish a baseline for future studies, we here analyzed the host-seeking behavior of the major malaria vector mosquito, Anopheles gambiae sensu strico, to human odor and carbon dioxide (CO2), under tightly controlled climatic conditions, and isolated from potential background contamination by the presence of an experimenter.

Sexual Systems of Plants in a Brazilian Montane Forest

Thus, we sought to characterize the frequency of sexual systems from species recorded in seed rain occurring in a tropical rainforest (Atlantic Forest) in Caparaó National Park, Espírito Santo State, Brazil. We collected the seed rain for twelve months, classified and recorded the species for: sexual system; pollination and dispersion syndrome; and fruit type. Then we measured the correlation between these attributes through correspondence analysis. Regarding sexual systems, 71% were hermaphrodites, 13% dioecious, and 11% monoecious. Hermaphrodites are best associated with pollination, dispersion and fruit types, represented by 65% of data variance. This study may contribute to elaborating management and conservation programs taking into account the interaction of plants with the local fauna.

Oil palm is one of the most rapidly expanding crops in Southeast Asia, but the impact of this crop on mosquito distribution, behaviour and exposure potential has been poorly explored. Understanding these factors is essential for developing, optimising and evaluating novel control measures aimed at reducing disease-transmission. -
3. the Importance of Bees in Nature
3. THE IMPORTANCE OF BEES IN NATURE BEES AS PART OF ECOSYSTEMS Pollinators strongly influence ecological relationships, ecosystem conservation and stability, genetic variation in the plant community, floral diversity, specialization and evolution. Bees play an important, but little recognized role in most terrestrial ecosystems where there is green vegetation cover for at least 3 to 4 months each year. In tropical forests, savannah woodlands, mangrove, and in temperate deciduous forests, many species of plants and animals would not survive if bees were missing. This is because the production of seeds, nuts, berries and fruits are highly dependent on insect pollination, and among the pollinating insects, bees are the major pollinators. In rain forests, especially in high mountain forests where it is too cold for most bees, other pollinators like bats and birds play a greater role in plant pollination. In farmed areas, bees are needed for the pollination of many cultivated crops (see Chapter 7), and for maintaining biodiversity in ‘islands’ of non-cultivated areas. The main role of bees in the different ecosystems is their pollination work. Other animal species are connected with bees: either because they eat the brood or honey, pollen or wax, because they are parasitic to the bees, or simply because they live within the bees nest. WHAT IS POLLINATION? Pollination is transfer of pollen from the anther (the male part of the flower) to the stigma (the female part of the flower). Some plants can pollinate themselves: in this case, the pollen passes from the anther to the stigma inside the same flower, and this is called self-pollination. -
