Abstract:
... The olive fly, Bactrocera oleae (Rossi), is the main pest in most olive-growing regions. During a 10-year study (2001–2011), olive fly population levels were evaluated in twenty olive groves in the region of Madrid, Spain, as part of the “European Program of Quality Improvement in Olive Oil and Table Olives”. The fly population data obtained by trapping with McPhail traps throughout the season and ...

Abstract:
... The proportion of diseased plant organs measured before chemical treatment is often used to make an assessment of the need for crop protection in agricultural plots, but such diagnostic tests are not perfect and sometimes lead to incorrect decisions. The area under the receiver operating characteristic (ROC) curve is a popular index of the overall performance of a test. It can be interpreted as th ...

Abstract:
... Gall Midge (Orseolia oryzae) is one of the serious insect pests of rice in Asia and South East Asia. In India, gall midge has been a particular problem because of the presence of five different biotypes in different geological regions. The annual yield losses due to gall midge have estimated to be in a range of 28-35%. The present study covers phenotyping of recombinant inbred lines (RILs) for gal ...

Abstract:
... Blackbirds, such as red-winged blackbirds (Agelaius phoeniceus), are notorious agricultural pests and damage crops at multiple stages of growth. Our aim was to test a novel deterrent, the use of sound designed to mask communication among birds (termed a “Sonic Net”), to deter blackbirds (Icteridae) from target areas of maturing sunflower crops. The Sonic Net masks communication of a target species ...

Trap cropping is one of these practices and involves luring insect pests away from the main crop to a more attractive host plant growing beside or around the crop. The trap crop can then be destroyed, and ...

Abstract:
... Conservation biological control (CBC) is a sustainable approach to pest management that can contribute to a reduction in pesticide use as part of an Integrated Pest Management (IPM) strategy. CBC is based on the premise that countering habitat loss and environmental disturbance associated with intensive crop production will conserve natural enemies, thus contributing to pest suppression. The abund ...

Abstract:
... Herbicide resistance is of increasing concern, especially as there is a lack of new modes of action. An assessment of resistance risk has been a key part of the pesticide authorisation process in most European countries since the early 2000's. However, little guidance is provided on how to quantify these risks. The risk matrix described here presents a quantitative approach to the evaluation of th ...

Abstract:
... Mycosphaerella graminicola is a fungal pathogen that causes Septoria leaf blotch in wheat, resulting in substantial crop losses in years conducive to infection. The disease is mainly controlled by the use of sterol 14α-demethylation inhibitor (DMI) fungicides, which target the CYP51 protein involved in sterol biosynthesis in the fungus. The field efficacy of these chemicals has however been declin ...

Abstract:
... The etiological agents of the yellow leaf syndrome (YLS) are the Sugarcane yellow leaf virus (ScYLV), and phytoplasmas of different groups. Due to a lack of knowledge on the occurrence of YLS and the importance of sugarcane to Brazil, the aims of this study were to assess the occurrence and distribution of the pathogens associated with YLS in sugarcane cultivation areas in three states of Northeas ...

Abstract:
... Whitefly-transmitted viruses are a growing threat to modern day agriculture. Their impact on South Africa's vegetable industry results in unprecedented economic losses. Tomatoes are important vegetable crops that are highly susceptible to whiteflies and an almost indispensable part of meal preparation in many South African homes. Against this background, tomato crops and nearby weed species in Sou ...

Abstract:
... Carob moth, Ectomyelois ceratoniae (Lepidoptera: Pyralidae) is the most important pest of pomegranate, Punica granatum (Punicaceae), in Iran. The most recommended procedure to control of this pest is collecting and destroying infested fruits in the orchards at the end of cropping season to eliminate overwintering sites. In order to determine the parasitoid species and the parasitism percentage dur ...

Thiamethoxam is a neonicotinoid insecticide that is used to manage the pepper weevil (Anthonomus eugenii Cano). A systemic bioassay method, using pepper seedlings, was developed to determine baseline toxicity data for both insecticides using a susce ...
