Dragonfly, any of a group of roughly 3,000 species of aerial predatory insects most commonly found near freshwater throughout most of the world. Add a case study or class simulation to encourage discussion and apply lessons. o Competition acts in density dependent manner. Summarize presentation content by restating the important points from the lessons. The parasitoid's host is usually in the same taxonomic class (Insecta). What will the audience be able to do after this training is complete? Some ecosystem services, such as the regulation and stabilisation of climate, water flow, and the Dept. Insects flourish up to 10 °C but below 6 °C mortality of certain insects like coleopterons species goes up to > 99 °C after 9 months at 45% R.H. storage conditions. ADVERTISEMENTS: Here is a list of four major microbial interactions:- 1. 1. “Rationality is the quality or state of being rational – that is, being based on or agreeable to reason. They gather nectar from a population of 560 flowering plants. Now customize the name of a clipboard to store your clips. The CFs of these species range between 40 kHz and 200 kHz, but the distribution of call frequencies is not random: frequencies lying close together are avoided, suggesting that resource partitioning may occur with respect to prey size as a mechanism for reducing interspecific competition for insect food (Heller and Helversen, 1989). Add slides to each topic section as necessary, including slides with tables, graphs, and images. For instance, attractants are pheromones which bind the members of a colony of social insects. It is the interactions between two organisms for nutrients, space, food, water, nesting sites .

TOPIC:SEASONALITY IN INSECTS In general, insects commonly confront two types of major environmental stresses. Entomology. Rationality implies the conformity of one’s beliefs with one’s reasons to believe, and of one’s actions with one’s reasons for action. Diapause vs. Quiescence Dormancy is a generic term for any state of naturally occurring ecological or evolutionary adaptations of arrested development, and usually accompanied with metabolic suppression. Classification of parasitoid Based on stages of attack Based on number per host Based on feeding type Based on tropic level (or) Food web relationship Based on host range Based on parasitism Based on other categories 2 Wim Vanderbauwhede.

This study and other examples of interspecific competition between plant—feeding insects indicate that more field experiments are needed before any conclusions can be drawn about the significance of competition for insect herbivores. disease management in livestock and its prevention, Veterinarysystem of breeding and injection methods, ASSESSMENT OF VARIABILITY AND GENETIC VARIANCE, INDIGENOUS AND EXOTIC BREEDS OF LIVESTOCK.

Genetics of insect viruses 6. The chapter focuses on genetic relations among castes in lower termites. This is another option for an Overview slides using transitions. A population of 820 insects lives in a 1.2-acre area. Life table – Interspecific and intraspecific relationship. Prev.(Ag.) For certain insects, it is possible to eradicate populations within discrete areas by the release of sterile males that successfully compete with the wild population. II. services (e.g. A life table shows how and how many insects die as they mature from eggs to adults. Pests – definition, categories and causes for outbreak of pests. Host: Those animals attacked by parasitoids. Interspecific interactions are herbivory, predation, competition, coevolution and symbiosis. Example : competition between humming birds & insects for nectar . J.K. Cronk, M.S. See our Privacy Policy and User Agreement for details. Medicinal plants importance,scope and uses. Pages 1063-1072. Fennessy, in Encyclopedia of Inland Waters, 2009. Why? Competition for limited resources is a widespread ecological interaction in animals. Give a brief overview of the presentation.

Types of parasitoids and parasitism ppt 1. Clipping is a handy way to collect important slides you want to go back to later. Plant-Microbe Interactions 3. INSECT ECOLOGY In the case of insect parasitoids, species can compete for host resources both at the adult stage as well as at the larval stage. You can change your ad preferences anytime. ), in which a larger or stronger organism excludes a smaller or weaker one from living space or deprives it of food, Dragonfly species are characterized by long bodies with two narrow pairs of intricately veined, membranous wings that, … Microbe-Microbe Interactions. Clay-Humus-Microbe Interaction: Clay mineral (and humic substances) affects the activity, ecology and population of microor­ganisms in soil. Briefly describe each objective how the audience will benefit from this presentation. Share Every company is now a tech company; API's can help stay competitive SlideShare. This technique is only suitable if there is a single mating. B. competition ininsects SEASONALITY IN INSECTS DIAPAUSE(Quiescence) Species separated by geographic areas encounter a great variation in climate changes and thus leading to variation in their life cycles, like variable number of generations per year (univoltine, bivoltine, multivoltine and non diapausing strains). A parasite-infected host may promote performance of associated insect vectors; but possible parasite effects on nonvector insects have been largely unexplored. Plant-insect signaling interactions: signals that plants receive from herbivores and other plants •Wounding: feeding or mechanical damages •Herbivore-associated molecular patterns (HAMPs) –Chemicals: Fatty acid-amino acid conjugate (FAC), caeliferins, 2-hydroxyoctadecatrienoic acid, bruchins, Competition Competition is the struggle for use of shared limiting resources . Application 6.3. ENT-505 This template can be used as a starter file for presenting training materials in a group setting. Which population has greater density, the insects or the plants?
