Establishment of Laboratory Bioassay System for Phyllotreta striolata Larvae and Screening of Novel Bt Cry Proteins

Toxins
Phyllotreta striolata is a global pest of cruciferous vegetables, and controlling its soil-dwelling larvae is challenging. The lack of standardized larval bioassay methods hinders the screening of effective biocontrol agents.

Improvement of biological control by volatile plant compounds [PDF]

, 2005
Compared to conventional farming the pest management strategies in organic farming is based on better plant resistance and sustainable cultivation technique that does not destroy the natural enemies of pest insects. Methods that reduce feeding efforts of

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

Pest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Micro-biological degradation and transformation of dissolved organic matter following continuous cropping of tobacco

Frontiers in Microbiology
In recent years, the problems associated with continuous cropping (CC) that cause soil degradation have become increasingly serious. As a key soil quality property, dissolved organic matter (DOM) affects the circulation of carbon and nutrients and the ...

Non‐triazine photosystem II inhibitors provide effective control of metabolic atrazine‐resistant Amaranthus tuberculatus

Pest Management Science, EarlyView.
Metabolism‐based atrazine‐resistant Amaranthus tuberculatus populations ACR and MCR exhibit little or no cross‐resistance to amicarbazone and metribuzin, suggesting that non‐halogenated Group 5 herbicides can be utilized to re‐establish effective control.

Organic Centre Wales Technical Note 6: Biology and management of leatherjackets [PDF]

, 2005
Leatherjackets are the larvae of crane flies (Tipula spp.) which are better known as daddy longlegs. The largest populations are found in grassland and populations in infested fields can reach 0.6 million leatherjackets/ha.

Rhizobacteria regulate colonising Sitobion avenae aphid populations through induced host resistance and alter plant volatiles promoting early parasitoid recruitment on barley (Hordeum vulgare)

Pest Management Science, EarlyView.
Rhizobacterial inoculation of barley reduced Sitobion avenae populations by inducing plant resistance and modifying volatiles that attracted parasitoid wasps earlier, enhancing both bottom‐up and top‐down pest control. Abstract BACKGROUND Soil rhizobacteria can enhance crop resistance to insect herbivores and influence higher trophic interactions ...

Effect of Insecticides and Plutella xylostella (Lepidoptera: Plutellidae) Genotype on a Predator and Parasitoid and Implications for the Evolution of Insecticide Resistance [PDF]

, 2017
In the laboratory and in cages in the greenhouse, we evaluated the toxicity of two insecticides (lambda-cyhalothrin and spinosad) on the parasitoid, Diadegma insulare (Cresson), and the predator, Coleomegilla maculate (DeGeer), both natural enemies of ...

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, EarlyView.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

Wildflower strips to reduce lepidopteran pests in cabbage crops [PDF]

, 2006
Vegetable production systems are highly intensive and the periodic cultivations lead to un-favourable conditions for natural enemies. Using non-crops it is possible to create ecological infra-structure offering suitable food for natural enemies, and ...
