Locust dynamics: Behavioral phase change and swarming

Locusts exhibit two interconvertible behavioral phases, solitarious and gregarious. While solitarious individuals are repelled from other locusts, gregarious insects are attracted to conspecifics and can form large aggregations such as marching hopper bands. Numerous biological experiments at the individual level have shown how crowding biases conversion towards the gregarious form. …

Larval exposure to a pyrethroid insecticide and competition for food modulate the melanisation and antibacterial responses of adult Anopheles gambiae

The insecticides we use for agriculture and for vector control often arrive in water bodies, where mosquito larvae may be exposed to them. Not only will they then likely affect the development of the larvae, but their effects may carry over to the adults, potentially affecting their capacity at transmitting …

In view of new insights being generated it is accentuated to reassess the system of sustainable plant disease management. One farmer-inspired indigenous …

Neem, the wonder tree, under attack: a new major pest

Azadirachta indica A. Juss. (Meliaceae), popularly known as neem, is a wellrecognized tree. Despite its insecticidal properties, neem in the Indian subcontinent is known to be infested by insect pests. In November 2009, mature neem trees in the village of Bhauli, Bakshi ka Talab, Lucknow, started defoliating and soon consumed …

Scientists confirm first report of egg parasitoid in Africa to fight fall armyworm

A group of scientists have confirmed the first report of an egg parasitoid Telenomus remus in Africa which could prove an important biological weapon in the fight against the devastating fall armyworm (Spodoptera frugiperda) that threatens the food security of more than 200 million people. Dr Marc Kenis, Head of …

A climate-adapted push-pull system effectively controls fall armyworm, Spodoptera frugiperda (J E Smith), in maize in East Africa

Fall armyworm,Spodoptera frugiperda(J E Smith), an economically important pest native to tropical and sub-tropical America has recently invaded Africa, causing substantial damage to maize and other crops. We eval-uated functionality of a companion cropping system,‘climate-adapted push-pull’, developed for control of cerealstemborers in drier agro-ecologies, as an added tool for the …

Maize benefits the predatory beetle, Propylea japonica (Thunberg), to provide potential to enhance biological control for aphids in cotton

Biological control provided by natural enemies play an important role in integrated pest management. Generalist insect predators provide an important biological service in the regulation of agricultural insect pests. Our goal is to understand the explicit process of oviposition preference, habitat selection and feeding behavior of predators in farmland ecosystem …

Worldwide decline of the entomofauna: A review of its drivers

Biodiversity of insects is threatened worldwide. Here, we present a comprehensive review of 73 historical reports of insect declines from across the globe, and systematically assess the underlying drivers. Our work reveals dramatic rates of decline that may lead to the extinction of 40% of the world's insect species over …

Traditional knowledge of people on plants used as insect repellents and insecticides in Raya-Azebo district, Tigray region of Ethiopia

The study aimed to document and assess local knowledge on the use of insecticidal and insect repellent plants to manage disease-transmitting, nuisance and crop pests in Raya-Azebo district of Tigray region of Ethiopia. Ethnobotanical data were collected through semi-structured interviews conducted with purposively selected informants. Simple preference ranking exercises were …

Indigenous methods of seed conservation and protection in Uttarakhand Himalaya

In Uttarakhand Himalaya traditional agriculture is the mere way to meet the subsistence needs of the local farming communities. In traditional system of agriculture, local seed material of traditional crop varieties plays an important role for crop production. In such a situation, the protection of seed material and its conservation …

Coexpression of potato type I and II proteinase inhibitors gives cotton plants protection against insect damage in the field

Potato type I and II serine protease inhibitors are produced by solanaceous plants as a defense mechanism against insects and microbes. Nicotiana alata proteinase inhibitor (NaPI) is a multidomain potato type II inhibitor (pin II) that is produced at high levels in the female reproductive tissues of the ornamental tobacco, …

Republished study: long-term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize

The health effects of a Roundup-tolerant NK603 genetically modified (GM) maize (from 11% in the diet), cultivated with or without Roundup application and Roundup alone (from 0.1 ppb of the full pesticide containing glyphosate and adjuvants) in drinking water, were evaluated for 2 years in rats. This study constitutes a …

Potential accumulative effect of the herbicide Glyphosate on Glyphosate-tolerant maize rhizobacterial communities over a three-year cultivation period

Glyphosate is a herbicide that is liable to be used in the extensive cultivation of glyphosate-tolerant cultivars. The potential accumulation of the relative effect of glyphosate on the rhizobacterial communities of glyphosate-tolerant maize has been monitored over a period of three years. Original Source

Tandem amplification of a chromosomal segment harboring 5-enolpyruvylshikimate-3-phosphate synthase locus confers glyphosate resistance in Kochia scoparia

Recent rapid evolution and spread of resistance to the most extensively used herbicide, glyphosate, is a major threat to global crop production. Genetic mechanisms by which weeds evolve resistance to herbicides largely determine the level of resistance and the rate of evolution of resistance. In a previous study, we determined …

The Pesticides Management Bill, 2017

A Bill to regulate the import, manufacture, export, storage, sale, transport, distribution, quality and use of pesticides with a view to— control pests; ensure availability of quality pesticides; allow its use only after assessing its efficacy and safety; minimize the contamination of agricultural commodities by pesticide residues; create awareness among …

Long-distance endosome trafficking drives fungal effector production during plant infection

To cause plant disease, pathogenic fungi can secrete effector proteins into plant cells to suppress plant immunity and facilitate fungal infection. Most fungal pathogens infect plants using very long strand-like cells, called hyphae, that secrete effectors from their tips into host tissue. How fungi undergo long-distance cell signalling to regulate …

Genetic elimination of field-cage populations of Mediterranean fruit flies

The Mediterranean fruit fly (medfly, Ceratitis capitata Wiedemann) is a pest of over 300 fruits, vegetables and nuts. The sterile insect technique (SIT) is a control measure used to reduce the reproductive potential of populations through the mass release of sterilized male insects that mate with wild females. However, SIT …
