Aphididae (Hemiptera) on ornamental plants in Córdoba (Argentina) Rev. Soc. Entomol. Argent.
Szpeiner,Alfonsina.
In 30 surveys across Cordoba city and surroundings (Argentina) I recorded, from November 2001 to May 2002, a total of 109 ornamental plants infested with aphid colonies. Surveys were conducted in the local botanical garden as well as homestead gardens and nurseries. Seventeen species of aphids were identified, 4 of which are new species in the area, from 47 ornamental plants. In a total of 59 plant/aphid associations, 38 new associations were found. I present the first record of aphids colonizing Cactaceae in Argentina. Most aphid colonies were medium and a high proportion (more than 40%) showed alate individuals. The most frequent aphid species, Aphis gossypii Glover and Aphis craccivora Koch were especially associated with the most frequent damages:...

Balancing Grower Protection Against Agency Concerns: An Economic Analysis of Contract Termination Damages AgEcon
Lee, Myoungki; Wu, Steven Y.; Fan, Maoyong.
This study examines legislation that would grant growers termination damages if their contracts are terminated. Our model suggests that, with no contracting frictions, damages would not reduce ex ante efficiency as processors can contract around damages through contract restructuring. Growers would earn less under continuation but would be protected if terminated, although overall expected profits would be unaffected. However, when contracting friction exist, then efficiency losses can occur as processors would be constrained in restructuring contractual incentives to deal with moral hazard. Growers' expected profits would increase while processors' profit would decrease.

Comparação dos sistemas de cultivo nativo e adensado de erva mate, Ilex paraguariensis St. Hil., quanto à ocorrência e flutuação populacional de insetos Rev. Bras. entomol.
Borges,Larissa R.; Lázzari,Sonia Maria Noemberg; Lázzari,Flávio Antonio.
This research was carried out in order to compare the occurrence of insects in two maté cultivation systems, native and high tree density. It was performed from August/2000 to September/2001, in a private property in São Mateus do Sul county, in Paraná State, Brazil. Visual inspections of trees and light traps were used to evaluate insect populations in both areas. For Hedypathes betulinus (Klug) (Coleoptera, Cerambycidae), only six adults were observed in the dense area. Based on presence of sawdust at the basis of the trunk, it was obtained that the number of attacked trees did not surpass 11% in either area. For Gyropsylla spegazziniana (Lizer y Trelles) (Hemiptera, Psyllidae), the number of galls per tree was counted and it was observed that the...

First record of Eucalyptus spp. bark-stripping by brown-capuchin monkeys (Sapajus nigritus, Primates: Cebidae). Repositório Alice
LIEBSCH, D.; MIKICH, S. B..
Conflitos envolvendo animais selvagens e plantios comerciais têm sido comumente registrados em todo o mundo, incluindo o descascamento de árvores nativas ou exóticas por primatas. No sul do Brasil, o macacoprego (Sapajus nigritus) é responsável por provocar danos em plantios comerciais de Pinus spp e Araucaria angustifolia. Nesse artigo, apresentamos de forma inédita na literatura o descascamento de Eucalyptus spp. por macacos-prego. Considerando o crescimento das áreas com plantios de eucaliptos no Brasil e países vizinhos, a informação apresentada aqui é de grande importância para a economia florestal. Ele também ressalta a necessidade de estudos científicos que visem minimizar os danos causados à produção sem comprometer a conservação da vida selvagem,...

Injuries caused by frankliniella spp. (thysanoptera: thripidae) on seedless grapes Ciência e Agrotecnologia
Moreira,Andréa Nunes; Oliveira,José Vargas de; Oliveira,José Eudes de Morais; Souza,Geisa Mayana Miranda de; Breda,Mariana Oliveira.
Thrips of the genus Frankliniella cause significant reduction on grape production. Little is known about its decision making approach in integrated pest management and information on thrips injuries to the vine is scarce, hindering the control of this pest. This study aimed to determine the species of thrips and injuries that cause damage to berries in seedless grapes clusters. The trial was conducted in an area cultivated with Vitis vinifera L., variety Thompson Seedless, using a randomized block design with five treatments and four replications. The treatments consisted of artificial infestation (zero, two, four and eight thrips per inflorescence), and treatment determined by the monitoring system of the grower. Each replication consisted of three plants...

Thrips species (Insecta: Thysanoptera) associated to Fabaceae of agricultural importance in Cerrado and Amazon-Caatinga ecotone from Brazilian Mid-North Biota Neotropica
Lima,Élison Fabrício Bezerra; Monteiro,Renata Chiarini; Zucchi,Roberto Antonio.
Little is known about the Thysanoptera fauna from Brazilian Mid-North. In spite of being a region with at least three biomes and some ecotones, the studies on this insect order in the region are related to associations to a few cultivated plant species. On Fabaceae, plant family with the second largest number of records of thrips species associated in Brazil and huge economic importance for Mid-North, there are thrips records only on cowpea (Vigna unguiculata (L.) Walp.). Due to the lack of knowledge on the Thysanoptera fauna in such a diverse area and the importance of crops of this family in the region, this research aimed to survey the thrips species associated to Fabaceae of agricultural importance in areas of Cerrado and Amazon-Caatinga ecotone in...

Torts and the Protection of "Legally Recognized" Interests AgEcon
Hoffmann, Sandra A.; Hanemann, W. Michael.
The law of torts plays an important role in completing the legal property rights system by defining the extent to which property is protected from harm. It does this by defining the kinds of interests that will be recognized and protected from harm by the courts, the duty of care owed these recognized interests by others, and the manner in which they will be protected through monetary compensation, restitution, or injunction. Together, these three elements of torts define a right in the "bundle of rights" that constitute property. In this paper, we develop a systematic approach to formalizing the nature of the property rights protected by tort law. We use this approach to reexamine the literature on compensation for nonpecuniary damages. This reexamination...

Valuing Catastrophic Citrus Losses AgEcon
Adams, Damian C.; Kilmer, Richard L.; Moss, Charles B.; Schmitz, Andrew.
Courts are often required to estimate changes in welfare to agricultural operations from catastrophic events. For example, courts must assign damages in lawsuits, such as with pesticide drift cases, or determine "just compensation" when the government takes private land for public use, as with the removal of dairy farms from environmentally sensitive land or destruction of canker-contaminated citrus trees. In economics, the traditional method of quantifying producer losses is estimating changes in producer welfare, but courts rarely use this method. Instead, they turn to substitute valuation methods that may not fully capture welfare changes, such as changes in land value, tree replacement value, and total revenue. This study examines various measures for...

Valuing Catastrophic Losses for Perennial Agricultural Crops AgEcon
Adams, Damian C.; Kilmer, Richard L.; Moss, Charles B.; Schmitz, Andrew.
Courts are often required to estimate changes in welfare to agricultural operations from catastrophic events. For example, courts must assign damages in lawsuits, such as with pesticide drift cases, or determine 'just compensation' when the government takes private land for public use, as with the removal of dairy farms from environmentally sensitive land or destruction of canker-contaminated citrus trees. In economics, the traditional method of estimating changes in producer welfare is the computation of lost producer surplus, but courts rarely use this method. Instead, they turn to substitute valuation methods that may not fully capture welfare change, such as changes in land value, tree replacement value, and total revenue. This study examines various...
