Give a brief overview of the presentation. ADVERTISEMENTS: Here is a list of four major microbial interactions:- 1. The distribution and abundance of insect populations can fluctuate over time for a variety of reasons including variations in climatic conditions, resource availability and accessibility, abundance and diversity of natural enemies, and intra- or interspecific competition. Many insects use repellant odors to protect themselves, and perhaps the best-known group of such insects is the stink bugs. This is another option for an Overview slides using transitions. In winged insects the adult differs in several respects from the young, such insects are said to undergo metamorphosis in becoming adults. Types of parasitoids and parasitism ppt 1. Some ecosystem services, such as the regulation and stabilisation of climate, water flow, and the 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, If you continue browsing the site, you agree to the use of cookies on this website.

GM Crops for long term food and Nutritional Security”, No public clipboards found for this slide. Interspecific competition can play a role in sizing and shaping community structures. Describe the major focus of the presentation and why it is important. Genetic relatedness among members of colonies of lower termites is influenced by the presence of multiple sex chromosomes, the sex of the individuals, the sex-ratio of the colony as a whole, the existence of replacement reproductives, and by the general level of inbreeding in the population.

Life table – Interspecific and intraspecific relationship. PPE -322(Insect Pests of Vegetable, Ornamental and Spice Crops)=(2+1) ... o When the food is in short supply there is intraspecific or interspecific competition. Interspecific interactions are herbivory, predation, competition, coevolution and symbiosis. Population dynamics – role of biotic factors – competition – parasitoids and predatots. A. Parasitoid: A parasitic insect that lives in or on and eventually kills a larger host insect (or other arthropod). Dragonfly species are characterized by long bodies with two narrow pairs of intricately veined, membranous wings that, … pollination, soil fertility, insect control and erosion control) that, if lost, are expensive and sometimes impossible to replace. services (e.g. The neotrophical social wasp Mischocyttarus drewseni applies a secretion to the stem of its nest that repels foraging ants.

Looks like you’ve clipped this slide to already. 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. Competition Competition is the struggle for use of shared limiting resources . Diapause and quiescence form two different types of dormancies in insects.

A cohort life table tracks organisms through the stages of life, while a static life table shows the distribution of life stages among the population at a single point in time. Many psocopteran and coleopterons species were dead almost 99% at 50 °C within 2.5 h [7]. DIAPAUSE-AESTIVATION ,HIBERNATION Pests – definition, categories and causes for outbreak of pests.

Clipping is a handy way to collect important slides you want to go back to later. Production of allelochemicals varies with environment and associated environmental stresses. In the case of insect parasitoids, species can compete for host resources both at the adult stage as well as at the larval stage. Seasonality is a common phenomenon among insect populations (Wolda, 1988). By, L.N.Nisha I-PhD-ENTOMOLOGY Types of parasitoids and parasitism 1 2. 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). Briefly describe each objective how the audience will benefit from this presentation. A parasite-infected host may promote performance of associated insect vectors; but possible parasite effects on nonvector insects have been largely unexplored.

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). It is the interactions between two organisms for nutrients, space, food, water, nesting sites . There are two basic modes: competition (q.v. Examples on the use of Insect Viruses in the Field 6.4.

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. Add a case study or class simulation to encourage discussion and apply lessons. Overpopulation refers to a population which exceeds its sustainable size within a particular environment or habitat. FACTORs AFFECTINGInterspecific competition ininsects ajaySharma{dept.of entomology} 2. 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. In general, insects commonly confront two types of major environmental stresses. Make your text as brief as possible to maintain a larger font size. See our User Agreement and Privacy Policy.

Clay-Humus-Microbe Interaction: Clay mineral (and humic substances) affects the activity, ecology and population of microor­ganisms in soil. It can occur in any plant organ (Rice, 1974), but roots, seeds, and leaves are the most common sources.Source becomes important for exploitation of allelochemicals for weed control.
