“…But modeling studies on mycosis prevalence of Entomphthorales in the host populations are scarce, especially in semi-natural habitats or open fields, due to the effects of the biotic and environmental factors and their interactions are complicated in natural epizootic development (9,14,19).…”

“…Unfortunately, most fungal biopesticides are produced on the basis of hypocrealen fungi, among which the majority belongs to polyphagous species that is a broad spectrum of potential hosts. Entomophthoralen fungi amongst many species are more specialized (monophagous), therefore not of interest among potential producers of mycoinsecticides because of difficulties in their cultivation on artificial substrates and the multiplication of infective material on a mass scale (Pell et al, 2001). …”

Forest Ecosystems - More Than Just Trees

View full text Add to dashboard Cite

The common idea for many people is that forests are just a collection of trees. However, they are much more than that. They are a complex, functional system of interacting and often interdependent biological, physical, and chemical components, the biological part of which has evolved to perpetuate itself. This complexity produces combinations of climate, soils, trees and plant species unique to each site, resulting in hundreds of different forest types around the world. Logically, trees are an important component for the research in forest ecosystems, but the wide variety of other life forms and abiotic components in most forests means that other elements, such as wildlife or soil nutrients, should also be the focal point in ecological studies and management plans to be carried out in forest ecosystems. In this book, the readers can find the latest research related to forest ecosystems but with a different twist. The research described here is not just on trees and is focused on the other components, structures and functions that are usually overshadowed by the focus on trees, but are equally important to maintain the diversity, function and services provided by forests. The first section of this book explores the structure and biodiversity of forest ecosystems, whereas the second section reviews the research done on ecosystem structure and functioning. The third and last section explores the issues related to forest management as an ecosystem-level activity, all of them from the perspective of the �other� parts of a forest.

“…After the death of the insects, the fungus breaks open the integument and forms aerial mycelia and sporulation on the cadavers [55]. The fungi of entomopthorales group are obligate pathogens of insects and cause host death by tissue colonisation with little or no use of toxins [56].…”

Insects, like other organisms, are susceptible to a variety of diseases caused by bacteria, viruses, fungi and protozoans, and these pathogens are exploited for biological control of insect pests through introductory or inundative applications. Microbial pathogens of insects are intensively investigated to develop environmental friendly pest management strategies in agriculture and forestry. In this paper, the scope for utilization of insect pathogens in pest management in the world and India is reviewed. The most successfully utilized insect pathogen is the bacterium, Bacillus thuringiensis (Bt) which is used extensively for management of certain lepidopteran pests. In India, mostly imported products of Bt kurstaki have been used, which are expensive and there is an urgent need to develop aggressive indigenous Bt strains against various pests. Baculoviruses comprising nuclear polyhedrosis virus (NPV) and granulosis virus (GV) have been successfully used as insect pathogens because of their high virulence and specificity. NPV and GV formulations are used for lepidopteran pests like Helicoverpa armigera (HaNPV) and Spodoptera litura (SlNPV) in India, besides Anticarsia gemmatalis NPV in Brazil, Lymanttria disper NPV, Orgyia pseudotsugata NPV in USA and GV of Pieris rapae in China. Lack of easy mass multiplication methods for the commercial production of baculoviruses calls for R&D to develop production in insect tissue cultures. Entomopathogenic fungi like Beauveria bassiana, B. brongniartii, Metarhizium anisopliae, M. anisopliae var. acridium, Lecanicillium spp., Hirsutella thompsonii, Nomuraea rileyi and Isaria fumosorosea are gaining importance in the crop pest control in recent years due to the simpler, easier and cheaper mass production techniques. Environmental humidity and temperature play an important role in the infection and sporulation of these fungi and as such they are highly suitable during cool and humid cropping seasons. Successful uses include M. anisopliae var. acridium for locust control in Africa, Australia and China, M. anisopliae in sugarcane spittle bug management in Brazil and pine moth (Dendrolimus spp.) control in China using B. bassiana. Since talc -based formulations of these fungi have limited shelf life of 3-4 months, alternative formulations with longer shelf life (12-18 months) have to be developed besides suitable oil based formulations for dry land agriculture. There is a scope to utilize the biodiversity of Entomophthorale group of fungi like Entomophthora, Zoophthora, Neozygites etc., which have potential for management of aphids, thrips and lepidopteran pests.
