State scientists create disease-resistant strawberry

Danbury News Times

The strawberry, named the Rubicon, is resistant to black root rot, caused by a microscopic worm, and the black vine weevil, a 19th-century import from Europe. Put the two together, and you can completely trash a strawberry's root system, Cowles said.
The root rot and the weevil have been an ongoing bane for strawberry farmers in New England and the United States. Farmers have to dig up diseased plants, and wait for pests to clear. They normally have to wait two or three years before they can plant strawberries in the same spot. Cowles got the mother plant from what he and colleagues refer to as the "death field," an experimental plot at the Valley Laboratory in Windsor.

Entomopathogenic Nematodes - Implementation into Crop Production Systems

Thirty years ago, the idea of using nematodes to control pest populations was vague promise held by the handful of researchers working with these obscure insect parasites. Today, they are no longer a laboratory curiosity but have begun to gain acceptance as environmentally benign alternatives to chemical insecticides.

A hundred different laboratories explore these nematodes and their bacterial symbionts in more than 60 countries from every inhabited continent. Worldwide examples of use of entomopathogenic nematodes in crop production systems show effectiveness against pests that were once thought impossible to control.

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.

Current Options for Managing Nematodes Pest of Crops in India

Plant parasitic nematodes can cause damage to almost all kinds of crops. Estimated annual yield losses in the world’s major crops due to plant parasitic nematodes is about 12.3%. In India, recent estimate showed nematode is responsible for about Rs.240 billion yield losses every year.

Judicious use of chemical nematicides could be applied for protection of many crops. Integration of various available practices is one of the current approaches for managing pest problems of crops. Current options for nematode management are cultural practices, physical methods, biointensive nematode suppression, botanicals and sensible use of chemical nematicides.

Considering importance of nematodes in the integrated pest management system, following low input plant protection technologies viz. summer ploughing, soil solarization, organic manuring, crop rotation, adjusting dates of sowing, growing resistant varieties, irrigation management, optimum fertilization, hot water treatment, clean cultivation, green manuring, inter/mixed cropping, judicious use of pesticides, integration of two or more above mentioned methods could be adopted for managing insect pest, diseases including nematodes in the crop production system.

In the review, economically important plant parasitic nematode problems of crops in India and their management options are briefly discussed by dr. Khan.

Robber flies are members of the fly family Asilidae. This is a large group of flies with some 7,000 species identified worldwide. All are predators on other insects.

Humans consider some species of insects hunted by robber flies to be pests. Therefore, robber flies are generally regarded to be beneficial. But not always. As it turns out, robber flies willingly make meals out of one of our favorite insects - the honey bee...

Fruit Fly National Program chief Arturo Saborío, told the website the equipment will sterilize Mediterranean fruit fly pupae Ceratitis capitata and Anastrepha spp., which will then be sent onto fruit farms. This will decrease fruit fly population and enable its control.

Intraguild predation among plant pests: western flower thrips larvae feed on whitefly crawlers

Omnivores obtain resources from more than one trophic level, and choose their food based on quantity and quality of these resources.

Researchers found that western flower thrips killed and fed especially on whitefly crawlers and that the incidence of feeding did not depend on host-plant species. The developmental rate and oviposition rate of western flower thrips was higher on a diet of cucumber leaves with whitefly crawlers than on cucumber leaves without whitefly crawlers, suggesting that thrips do not just kill whiteflies to reduce competition, but utilize whitefly crawlers as food.

Chestnut Extracts in Managing Soilborne Plant Pathogens

Hao JJ et al. (2012) studied antimicrobial activity of chestnut extracts for potential use in managing plant pathogens.

Chestnut extracts were studied for antimicrobial activity against selected microorganisms, including plant pathogens. Most test microorganisms were inhibited by the extracts at different effective concentrations for 50% growth inhibition (EC50). Pseudomonas fluorescens was the most sensitive, Phytophthora cambivora was one of the least inhibited, and Cryphonectria parasitica was not inhibited.

Extracts of the Japanese × European chestnut (Castanea crenata × C. sativa) ‘Colossal’ showed a greater inhibition than those of wild trees of the Chinese species (C. mollissima).

Pellicle and shell tissue reduced radish scab disease caused by Streptomyces scabies in the greenhouse.

Management of Pest and Beneficial Insects Cotton Cropping Systems in Australia

Management of Pest and Beneficial Insects Cotton Cropping Systems in Australia | Natural Pest Control | Scoop.it

IndianJournals.com - A review is published on Exploitation of semiochemicals for the management of pest and beneficial insects with special emphasis on cotton cropping systems in Australia.


The paper examines semiochemicals, substances or mixtures of substances produced by one species that influence the behaviour of receptor organisms, from the perspective of their potential in a sustainable pest management context. Particular reference is made to Helicoverpa spp. and their natural enemies on cotton and to those chemical components derived from the inner tissues and organ surfaces of plants. The post-alightment behavioural sequence of insect pests such as Helicoverpa spp. which lay eggs on plants which are not a food source, includes the sensing of small quantities of many types of chemical substances that may include free amino acids, organic acids, sugars, secondary metabolites, vitamins, minerals, growth regulators, etc. Detection of these substances on the leaf or organ surfaces of the plant provides specific information to the female insect on plant health, physiology and nutrition that guides the insect to either accept or reject the plant for oviposition. Three behaviour manipulation methods for pest management have been identified as (1) a behaviour of the pest, (2) a means by which the behaviour is manipulated appropriately, and (3) a method that utilizes the behavioural manipulation method for the protection of the resource from the pest.

Several Trichogramma wasps species are known to be parasiotids of buterfly family (Lepidoptera). Trichogramma species are the most widely-studied agents of biological control in the field of entomology. But it is less known, that they can be also registered as insecticides.


In PAN Pesticides Database Trichogramma pinto and T. evanescens could be found among chemicals: identification, toxicity, use, water pollution potential, ecological toxicity and regulatory information is given also for these beneficial organisms like for any other pesticide. 

Data on 6,500 pesticides, insecticides and herbicides including toxicity, water pollution, ecological toxicity, uses and regulatory status is provided in Pesticides Action Network database.
