Abstract:

Increased production of insects on a large scale for food and feed will likely lead to many novel challenges, including problems with diseases. We provide an overview of important groups of insect pathogens, which can cause disease in insects produced for food and feed. Main characteristics of each pathogen group (viruses, bacteria, fungi, protists and nematodes) are described and illustrated, with a selection of examples from the most commonly produced insect species for food and feed. Honeybee and silkworm are mostly produced for other reasons than as human food, yet we can still use them as

Abstract:

Banana blood disease (Blood Disease Bacteria, BDB) caused by Ralstonia solanacearum Phylotype IV is the most important banana disease in Indonesia. So far, information on the spread of disease by insects is very limited. The research was aimed to determine the role of insect as a disseminator of R. solanacearum Phylotype IV and to determine the amount of BDB inoculum carried by each individual insect. The experiment was conducted in May - September 2008. Samples of insects (adult insects, the young insects, larvae, eggs), nectar, and pollen were taken from a colony of Trigona spp. collected fr

Abstract:

A continuous-time and deterministic model was used to characterize plant virus disease epidemics in relation to virus transmission mechanism and population dynamics of the insect vectors. The model can be written as a set of linked differential equations for healthy (virus-free), latently infected, infectious, and removed (postinfectious) plant categories, and virus-free, latent, and infective insects, with parameters based on the transmission classes, vector population dynamics, immigration/emigration rates, and virus-plant interactions. The rate of change in diseased plants is a function of

Diseases and insects, particularly those that are non-native and invasive, arguably pose the most destructive threat to North American forests. Currently, both exotic and native insects and diseases are producing extensive ecological damage and economic impacts. As part of an effort to identify United States tree species and forests most vulnerable to these epidemics, we compiled a list of the most serious insect and disease threats for 419 native tree species and assigned a severity rating for each of the 1378 combinations between mature tree hosts and 339 distinct insect and disease agents.

Abstract:

The fungal pathogen Fusarium circinatum (Nirenberg and O’ Donnell) is the causal agent of pine pitch canker (PPC) disease, which seriously affects conifer species in forests and nurseries worldwide. In Europe, PPC is only established in the Iberian Peninsula; however, it is presumed that its range could expand through the continent in the near future. Infection caused by this fungus requires open wounds on the tree, including physical damage caused by insects. Therefore, a relationship probably occurs between PPC and a wide variety of insects.

The successful control of insect-borne plant pathogens is often difficult to achieve due to the ecologically complex interactions among pathogens, vectors, and host plants. Disease management often relies on pesticides and other approaches that have limited long-term sustainability. To add a new tool to control vector-borne diseases, we attempted to block the transmission of a bacterial insect-transmitted pathogen, the bacterium Xylella fastidiosa, by disrupting bacteria–insect vector interactions. X. fastidiosa is known to attach to and colonize the cuticular surface of the mouthparts of vect

Abstract:

Entomopathogenic fungi are very heterogeneous group used for management of insect pest. From last 2 decade in the search for new avenues in biological control, the importance of entomopathogens has been highlighted as an environmental friendly pest control method came in existence which is sustainable solution towards integrated pest control program. Fungi, which induce disease symptoms in insects, include fungi from quick killers to absolute parasites that provide disease symptoms in the host. Insect order and families are reviewed which were affected severely by entomopathogenic fungi.

Abstract:

Insects can be effective vectors of plant diseases and this may result in billions of dollars in lost agricultural productivity. New, emerging or introduced diseases will continue to cause extensive damage in afflicted areas. Understanding how the vector acquires the pathogen and inoculates new hosts is critical in developing effective management strategies. Management may be an insecticide applied to kill the vector or a host plant resistance mechanism to make the host plant less suitable for the vector. In either case, the tactic must act before the insect performs the key behavior(s) result

Abstract:

One of the major, if not the major impediment to large scale increases of human insect consumption, is the strong rejection of insects as food by most of the world’s population. In an effort to understand this aversion, we surveyed online samples of adults living in the USA and India to participate in a study on ‘attitudes toward food’. A substantial proportion of both Americans (72%) and Indians (74%) were at least willing to consider eating some form of insect food. Men were more willing to try eating insects than were women, especially in the USA. Disgust seems to be the most common reactio

Abstract:

Several experimental procedures were used to evaluate the influence of solar radiation on insect infestations in Calimyma and Adriatic variety figs (Ficus carica L.). Direct sunlight eliminated infesting insects and prevented further infestation of ripe figs drying on the ground for at least 10 days. Placement in the shade resulted in 12% insect infestation in figs within 3 days. Figs that fell naturally into sunlit areas contained almost no insects, whereas 31% of figs that fell into dense shade were infested. While ripening figs were still attached to trees, the level of insect infestation w

Edible insects represent an understudied food resource that may promote human health. They characteristically contain ample protein, healthy fatty acids, minerals, and vitamins, and have been touted for their environmental benefits given their efficient resource use. While numerous in vitro, animal, and nutrient quantification studies have elucidated a framework of potential health impacts of entomophagy, few have measured direct health outcomes. This review investigates and summarises existing evidence on health impacts derived exclusively from human interventions. A systematic literature sea

Abstract:

Both human and insect societies depend on complex and highly coordinated infrastructure systems, such as communication networks, supply chains and transportation networks. Like human-designed infrastructure systems, those of social insects are regularly subject to disruptions such as natural disasters, blockages or breaks in the transportation network, fluctuations in supply and/or demand, outbreaks of disease and loss of individuals. Unlike human-designed systems, there is no deliberate planning or centralized control system; rather, individual insects make simple decisions based on local inf

Abstract:

Cardiac glycosides, cardenolides and bufadienolides, are elaborated by several plant or animal species to prevent grazing or predation. Entomologists have characterized several insect species that have evolved the ability to sequester these glycosides in their tissues to reduce their palatability and, thus, reduce predation. Cardiac glycosides are known to interact with the sodium- and potassium-activated adenosine triphosphatase, or sodium pump, through a specific receptor-binding site. Over the last couple of decades, and since entomologic studies, it has become clear that mammals synthesize
