BBSRC Feature: Using their genes against them: Fighting insect pests with genetic targeting (2013)

BBSRC Feature: Using their genes against them: Fighting insect pests with genetic targeting (2013) | Natural Pest Control | Scoop.it

When you look out on a golden-yellow field of oilseed rape you might not think you're seeing a battleground, but crops including oilseed rape, wheat, potato and tomato are engaged in a constant fight with pests and disease, trying to stay one step ahead.

As the world's human population looks set to increase to nine billion people by 2050, keeping plants healthy and productive is going to be essential to making sure there is enough food to go round.Aphids damage crops by feeding on them and transmitting plant diseases. "Crop pests are emerging earlier due to global warming and new variants are arriving from other countries, bringing new plant viruses", said Dr Saskia Hogenhout from the John Innes Centre (JIC) in Norwich, an institute strategically funded by the BBSRC.

 

Among these pests whitefly and green peach aphids cause hundreds of millions of pounds of damage and loss to crops through transmitting viruses and feeding. Both species are notorious for demonstrating the ability to rapidly develop resistance to conventional pesticides, and both attack a wide variety of crops, including cabbage, lettuce, beet, oilseed rape and potato. In UK cereal crops aphids alone can cause yield losses of over 40 per cent, and insect pests are responsible for an estimated 15 per cent of all crop losses globally. Dr Hogenhout said: "The aphids and whitefly themselves are problematic but they also transmit more than half of all plant viruses. They're called the mosquitoes of plants because like mosquitoes they feed on the vascular system and they transmit quite a number of viruses."

Knapco's curator insight, January 12, 2013 2:57 PM

Very promissing non-chemical method to combath aphid and whitefly species in the future! Whiteflies suffer from an identity crisis, as they are not flies at all, in appearance they resemble tiny, pure white 'moths' but are in fact, closely related to sap-sucking aphids. Aphids and whiteflies can both cause severe damage to wide range of crops by sucking sap from the plant, resulting in damages of the leaves, as well as leaf loss, wilting and stunting. Not only do they feed on plants, but they also produce honeydew, which spoils the plants' appearance, attracts ants and black sooty mould. Both can also transmit different species of plant viruses, which cause further damage to crops. Until the gene silencing methods are applied, biologocial control could be used as alternative to insecticide's use.

Natural Pest Control Options Creates Paradigm Shift

Natural Pest Control Options Creates Paradigm Shift | Natural Pest Control | Scoop.it
One of the first natural pest control products ever introduced into the market was Diatomaceous Earth. This is definitely one of the best pest control products if your goal is to only use non-toxic methods for dealing with your ...
Knapco's insight:

Forced Green states that diatomaceous earth can be used on a variety of pests. Slugs, ants, roaches, spiders, silverfish, fleas, beetles and bed bugs are just a few of the victims that this natural pest control method can wreak havoc on. Though diatomaceous earth is lethal to insects, it is completely harmless to humans and pets alike. The one disadvantage to this product is its nature of use, it needs to be applied virtually everywhere an insect can get into, this is about every crack and cranny around your home! Still, it has been proven to be very effective for ant control.

Organic Eprints - Monitoring Agriotes lineatus and A. obscurus in organic production using pheromone traps

Organic Eprints - Monitoring Agriotes lineatus and A. obscurus in organic production using pheromone traps | Natural Pest Control | Scoop.it

Wireworms, particularly Agriotes lineatus and A. obscurus are becoming a problem in organic crop production causing economically severe damage on potatoes and other arable crops. Since pesticide application for direct control is not allowed in organic farming, reliable methods for quantifying wireworm infestation levels and forecasting damage are urgently needed for any control strategy. In the present work, the assessment of the range of attractiveness of pheromone traps to male A. lineatus and A. obscurus beetles was investigated in 2006 and 2007. The results indicated that the trap recovery rate of released beetles was more dependent on release distance than on time. Recovery rates greater than 40% were only noted for short release distances (up to 10 m), while less than 10% of the beetles released at a distance of 60 m returned to the traps. Recovery rates of click beetles were also negatively affected by cold and wet weather conditions. Most of the beetles were recovered within the first 3 days.

Grafting Tomato to Manage Bacterial Wilt Caused by Ralstonia solanacearum in the Southeastern United States

Grafting Tomato to Manage Bacterial Wilt Caused by Ralstonia solanacearum in the Southeastern United States | Natural Pest Control | Scoop.it

Bacterial wilt, caused by Ralstonia solanacearum, can result in severe losses to tomato (Solanum lycopersicum) growers in the southeastern United States, and grafting with resistant rootstocks may be an effective strategy for managing this disease.

Leaf 'stamp' could detect crop diseases - SciDev.Net

Leaf 'stamp' could detect crop diseases - SciDev.Net | Natural Pest Control | Scoop.it

A technique that stamps biosensors directly onto the leaves of plants could be used as an early-warning system for crop diseases. Farmers will be able to isolate a diseased plant to prevent the spread of diseases.

 

Around 30 per cent of maize in Tanzania is contaminated with aflatoxin - a consequence of infection by fungi such as Aspergillus and Fusarium, which produce mycotoxins. Mycotoxins stunt children's growth, cause liver cancer and suppress the immune system. The UN Food and Agriculture Organization estimates that mycotoxins infect around a quarter of the world's crops every year, wasting one billion metric tons of food.

The Gates Foundation's Grand Challenges Explorations fund provides grants of US$100,000 for innovative 18-month projects for development of colorimetric tests -a self-inking stamp that delivers the chemicals that detect the toxins directly into plant leaf veins, possibly via fine needles incorporated into the stamp to ensure the reagents get inside. The stamp could be used 200 times and might cost US$10.

Tiny wasp may hold key to controlling kudzu bug - Online Athens

Tiny wasp may hold key to controlling kudzu bug - Online Athens | Natural Pest Control | Scoop.it

Tiny wasp may hold key to controlling kudzu bug Online Athens“Using classical biological control is an option in the tool kit,” said Ruberson, an entomologist in the UGA College of Agricultural and Environmental Sciences.

Ruberson’s parasitoid of choice is Paratelenomus saccharalis, a tiny wasp no larger than the period at the end of this sentence. The wasp lays its own egg in each kudzu bug egg, and the developing wasp larva destroys the kudzu bug egg as it develops.  

The kudzu bug was first spotted in Georgia in the fall of 2009. It feeds on kudzu, soybeans and other legumes and has become a nuisance to homeowners and a threat to international trade as an agricultural contaminant.

Five Arizona Pest Control Tips For Your Garden

Five Arizona Pest Control Tips For Your Garden | Natural Pest Control | Scoop.it

You can use some non-chemical sprays that often have the effect of giving the vegetation an unsavory taste to them, and this can in turn keep them away. If you put up sticky traps in your garden, you can achieve your objective. These traps have a specific color, so as to attract a certain kind of pest, and if you use them every five feet or so, you’ll have some pretty good results.

BUT:

To get rid of slugs add some bleach into a water spray bottle and spray the liquid all around the house, garden area, backyard, this will help keep the slugs under control. It is said that salt can get this done as well, so if you want to use that in your garden we certainly wouldn’t advise you not to.

NATURAL INSECT CONTROL IN THE GARDEN

NATURAL INSECT CONTROL IN THE GARDEN | Natural Pest Control | Scoop.it

The majority of insects you find in your garden are actually harmless and require no intervention. They are either nature’s helpers or food sources for nature’s helpers. For those insects that do pose a threat to some of your plants there are several non-invasive solutions you can utilize to prevent, monitor and control these pest insects.

This approach to pest management is called IPM or integrated pest management. Their premise is simple, begin with the least invasive and most environmentally sound treatments, gradually working your way up to the more invasive treatments (only if it becomes necessary).

Integrated Pest Management

Integrated Pest Management | Natural Pest Control | Scoop.it
FAO: Integrated Pest Management (IPM) is an ecosystem approach to crop production and protection that combines different management strategies and practices to grow healthy crops and minimize the use of pesticides.DeBugged: IPM is a term we use in the pest control industry to define a service standard that is both environmentally conscious and highly effective.Bajwa&Kogan (2002): Compendium of IPM Definitions; What is IPM and how is it defined in the Worldwide Literature? Integrated Plant Protection CenterAnon: "Interesting how countries do the same job but using different terminology for the same principles of IPM. In the UK, Europe & most of Asia they use ERDM: Eradicate, Restrict, Destroy, Monitor. But in the end it boils down to professional pest control carried out in an responsible manner."

Country's 'plant clinics' aid farmers without chemicals
Chinadaily USA
China has recently introduced "plant clinics", a new way to prevent and control plant diseases and insect pests on farmland.
Knapco's insight:

China has recently introduced "plant clinics", a new way to prevent and control plant diseases and insect pests on farmland.

Nine plant clinics to date have been jointly set up by CABI, a research group in the United Kingdom that focuses on agriculture and the environment, and agricultural authorities in Beijing and South China's Guangxi Zhuang autonomous region.

The plant clinics already are improving harvests for farmers while seeking to build public confidence in food safety by reducing the use of agrochemicals, insiders said.

Don't destroy research · Sense about Science | Natural Pest Control | Scoop.it

An appeal from scientists at the publicly funded research; calling for discussion not destruction of trials & research on GMO wheat and seeking support with the petition.

John Pickett, Scientific Leader of Chemical Ecology, Rothamsted Research: “On 27th May 2012 protesters are planning to destroy our Chemical Ecology group’s scientific research because it uses genetically modified wheat. Growing wheat has an environmental toll of extensive insecticide use to control aphid pests. The research, which is non-commercial, is investigating how to reduce that by getting the plants to repel aphids with a natural pheromone. We are appealing for protesters to call off the destruction and discuss the work.”

Agriculture and Forestry - Pest Exclusion: Why it Matters for Commercial Pest Control

Agriculture and Forestry - Pest Exclusion: Why it Matters for Commercial Pest Control | Natural Pest Control | Scoop.it

Pest exclusion is a preventative tactic that involves sealing up areas of your building where pests are likely to enter, basically denying them access.

Today, more businesses are choosing to apply the principles of integrated pest management; a more holistic and healthy form, instead of using toxic chemicals. This method works with the environment, biology and natural life cycle of pests to help curb populations. The following describes how commercial pest control services use pest exclusion techniques to prevent infestations from happening.
