medicinal plant powders have traditionally been used as grain protectants against stored-product insect pests. in this study, insecticidal activity of carum copticum l. and cuminum cyminum l. powders was assessed on adults of sitophilus granarius l. and tribolium confusum jacquelin du val. experiments were carried out on wheat at 27 ± 1 ºcand 55 ± 5% r. h. the mortality increased with increasin...

Knowledge and information related to all aspects of crop-pest system are the foundations on which modern pest management decisions are based. The transfer of research and extension information to farmers plays the key role in the adoption of integrated Pest Management (IPM). FuzzyXPest is proposed to provide information to the farmers and researchers through the Internet using fuzzy expert syst...

Integrated pest management strategies were adopted to combat the coffee berry borer (CBB) after its arrival in Hawaii in 2010. A decision tree framework is used to model the CBB integrated pest management recommendations, for potential use by growers and to assist in developing and evaluating management strategies and policies. The model focuses on pesticide spraying (spray/no spray) as the mos...

Five herbivorous introduced mammals are sympatric in the central Southern Alps. All of these species have the potential to affect conservation values, yet the Department of Conservation at present monitors and mitigates the impacts of only one. We outline ecological arguments for multi-species management of sympatric herbivore pest impacts and use the two-species system of sympatric thar and ch...

In order to improve the level of adoption of integrated pest management (IPM), it is important to understand the benefits of integrating IPM practices. Integrated systems are less prone to failure and, when they incorporate natural enemies, they are also more resilient than systems that rely on a single method of pest suppression. The impact of changing IPM practices on the pest population dyna...

In the mid 1980’s, management of Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), in brassica vegetable crops was at crisis level with spray failures prevalent across the industry in Southern Queensland. Insecticide resistance to synthetic pyrethroids was identified in 1986, and resistance monitoring between 1988 and 1992 showed that problems also existed with carbamates, ...

Infestations of corn rootworms (Coleoptera: Chrysomelidae) create economic and environmental concerns in the Corn Belt region of the United States. To supplement the population control tactics of areawide pest management programs, we believe that a better understanding of the spatial relationships between biotic and abiotic or physical factors at the landscape scale is needed. Our research used...

A mail survey was conducted to assess current computer hardware use and perceived needs of potential users for software related to crop pest management in Nebraska. Surveys were sent to University of Nebraska-Lincoln agricultural extension agents, agribusiness personnel (including independent crop consultants), and crop producers identified by extension agents as computer users. There were no d...

Due to the important role of arbuscular mycorrhizal fungi (AMF) in ecosystem functioning, determination of the effect of management practices on the AMF diversity in agricultural soils is essential for the sustainability of these agro-ecosystems. The objective of this study was to compare the AMF diversity in Prunus persica roots under two types of fertilisation (inorganic, with or without manu...
