Energy, Agriculture, And Food: National, County, City Considerations, Gigi Berardi
Gigi Berardi
The objective of this paper is to evaluate the available information, assess the specific situation in Whatcom County, and make recommendations on reducing vulnerability to peak oil. The paper includes a discussion of energy use in agriculture, identification of particularly vulnerable areas, and suggestion of ways to reduce the vulnerability of the county‘s agriculture and, indeed, the entire food system to peak oil and volatile energy prices.

Behavioral Explanations Underlying The Lack Of Trap Effectiveness For Small-Scale Management Of Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Patrick C. Enstrom, Carissa A. Schoenick

Traps containing a combination floral and synthetic pheromone lure are used to monitor and manage Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae). One key factor limiting trap effectiveness for beetle control is the "trap spillover" phenomenon, in which the trap attracts beetles without capturing them, resulting in increased damage to surrounding host plants. We investigated the mechanisms underlying trap spillover by conducting two studies in a soybean field in east central Illinois. In the first study, we set up trap stations for 1 d and compared the sex, size, and egg load (for females) of beetles caught in the traps …

New Models Of Emergence Traps For Endophytic Egg Parasitoids Capture, Rodrigo Souza Santos Rss

For strain selection studies of natural enemies from the field, studies of behavior or even of taxonomy, capture of alive insects are of great importance. One alternative for obtaining adult parasitoids (Hymenoptera) is the use of emergency traps. Therefore, the objective of this work was to propose two models of emergency traps (traps like “box” and “bottle”), for obtaining alive endophytic egg parasitoids. The two models proposed were efficient in the capture of alive parasitoids, however a larger capture of specimens was observed in the “box” trap in relation to the e “bottle”, due to larger folioles storage inside the …
Diversity And Spatial Distribution Of Ground Arthropods In Agroecosystems, Rodrigo Souza Santos Rss
Diversity And Spatial Distribution Of Ground Arthropods In Agroecosystems, Rodrigo Souza Santos Rss

The knowledge of the diversity and distribution of ground arthropods contributes for the development of sustainable agricultural systems. This work was carried out at the Paulista State University, Jaboticabal campus, State of São Paulo, Brazil, during the period from February to April 2004. The objective was to analyse the community of Carabidae, Staphylinidae, Formicidae e Araneae through faunistic indexes, to determine the spatial distribution and interespecific interactions of predominant species in soybean (Glycine max (L.) Merr.), corn (Zea mays L.) and rubber tree (Hevea brasiliensis Muell. Arg.). The arthropods were sampled by pitfall traps distributed each 10 m in two …
Kenya — Starvation And Food Insecurity In The Land Of Plenty, Gigi Berardi
Kenya — Starvation And Food Insecurity In The Land Of Plenty, Gigi Berardi
Gigi Berardi
My last month in Kenya has been sobering. Ten million Kenyans were reportedly facing starvation. There were daily reports on affected districts, those most vulnerable, and the government’s mishandling of the disaster. Newspapers reported heavily on the incompetency of the National Cereals and Produce Board (NCPB), which is responsible, under the guidance of Trustees, in maintaining a Strategic Grain Reserve of about 6 million bags of maize cereal. How best to do this? An obvious way is through purchase of local grain supplies. Despite drought and resultant famine, poor infrastructure, high farm input costs, serious planting disruption after last year’s …
