Cannabis production is different from all other agriculture because it is illegal to federally register a pesticide for control of insects and disease. The Washington State Department of Agriculture has developed a list of products that are considered not illegal to use on cannabis in Washington. Many of these products have no practical pest management value. Many other of these products have limited efficacy, short residual or other attributes that limit their usefulness to cannabis growers. Due to the expectation of superior quality and the extremely high value of their crop, cannabis growers are under heavy pressure to control insects, mites and diseases. Due to the combination of these factors growers are using a wide array of pest management products and practices, some of which may be illegal and may pose a risk to pesticide applicators, cannabis workers and cannabis consumers. This situation is exacerbated by a federal probation on Washington State University and USDA conducting pest management research, development of alternatives to pesticides, pesticide applicator training or training on worker protection from pesticides. The lack of appropriate mechanisms for pesticide applicator and worker protection standards training, the lack of adequate crop protection tools and the absence of traditional research and extension outreach programs has created a “Wild West” mentality where any kind of pest management tactics can occur. The void of traditional pest management research, extension and appropriate tools has created serious and potentially dangerous conditions in cannabis production. This is not a new occurrence. Following a pesticide label has historically not been among the most important considerations in the illegal production of cannabis. What is difference is the cannabis is legally available for medical purposes for the large majority of the U.S population and is completely legal in several states. The widespread legalization of cannabis is bringing historical cannabis pest management practices into public view. Recent state investigations in Colorado, Oregon and Washington has indicated that illegal pesticide use is not uncommon in the cannabis industry. 6 UPDATE ON CURRENT ERADICATION PROGRAMS BY THE OREGON DEPARTMENT OF AGRICULTURE C.

  • (Hemiptera-Heteroptera: Notonectidae) of the ORIENTAL REGION
    Pacific Insects 10(2): 353-442 20 August 1968 THE ENITHARES (Hemiptera-Heteroptera: Notonectidae) OF THE ORIENTAL REGION By I. Lansbury HOPE DEPARTMENT OF ENTOMOLOGY, UNIVERSITY MUSEUM, OXFORD Abstract: This paper redescribes most of the species recorded from the Oriental Region. Keys to both sexes are given. Fifteen species and 1 subspecies are described for the first time. Five species are placed in synonymy and three previously described species have proved unrecognisable. This paper embodies the results of a study of the Oriental species of the genus Enithares. The main purpose being to collate the scattered descriptions and information concerning this genus. The geographical scope is limited to those species occurring east of the 60° of longitude. African, Mascarene and American species are excluded. No phylogenetic speculation is implied in any part of this paper. Wherever possible types have been examined in order to fix the species. In a few cases where types are no longer extant or available for study, I have utilized 'compared' specimens or the concept of the last reviewer. Full details are given under the relevant species. Acknowledgments: Many people have assisted in the preparation of this paper. In particular, I am deeply indebted to Dr G. Byers of the University of Kansas for making available to me a copy of G.T. Brooks unpublished thesis on Enithares. To Miss S. Na­ kata and Dr P. D. Ashlock of the Bishop Museum, Honolulu for the very large collection of un-named material sent to me. A glance at the location of many of the types of new species will show how valuable their contribution has been.

Abstract This article presents a detailed overview about one of the most important yet neglected fields of science, the Taxonomy, its relevance and the various impediments faced by it in recent times. Since the period 2011-2020 has been declared the Biodiversity decade, the Convention of Biodiversity has laid major emphasis on the inventory and conservation of biodiversity. However, it is a fact that the ignorance about our faunal and floral wealth can be detrimental for our own survival. With the decline in taxonomy and the disappearance of taxonomists worldwide, we are slowly heading towards a state of uncertainty and chaos as most of our studies require an accurate identification of test organism which is not a job that anyone or everyone can do.

Univ. de Costa Rica, 11501-2060, San José, Costa Rica Neotropical Entomology 37(4):436-448 (2008) Hemipteran Diversity (Cicadellidae and Clastopteridae) in Three Coffee Production Zones Affected by Xylella fastidiosa (Wells et al.) in Costa Rica ABSTRACT - A survey was conducted during 2002, 2003 and 2004 to determine the leafhopper species composition, abundance, richness, diversity, evenness, occurrence and fl ight activity among three coffee production zones of Costa Rica. Yellow sticky traps were used to qualify and quantify the number of aerial leafhoppers during the sampling period. A total of 82,500 individuals, belonging to 139 species within nine leafhopper subfamilies, were trapped. San Isidro de León Cortés site presented the highest diversity from the three surveyed sites. Twenty fi ve species were frequently trapped at least in one of the studied zones, and only Coelidiana sp.1, Osbornellus sp.1, Scaphytopius sp.1 and Empoasca sp. were trapped throughout the sampling period. The fl ight activity of the taxa that contain the main vectors of Xylella fastidiosa Wells et al. showed differences among the sampling zones. KEY WORDS: Auchenorrhyncha, leafhopper, fl ight activity RESUMEN - Se realizó un estudio durante los años 2002, 2003 y 2004, con el fi n de determinar la composición, la abundancia, riqueza, diversidad, equidad, ocurrencia y fl uctuación temporal de las especies de saltahojas en tres zonas productoras de café de Costa Rica.
