Leafminers (Diptera: Agromyzidae) are pests of various crops, mainly in greenhouses, and have Diglyphus spp. as important leafminer larval parasitoids. Until recently, only Diglyphus insularis (Gahan) had been reported in Brazil. In here we report the first records of Diglyphus begini (Ashmead), D. intermedius (Girault) and D. isaea (Walker) in Brazil. These parasitoids were found parasitizing ...

Botrytis cinerea is an important pathogen that causes diseases in ornamental crops. In presentresearch several greenhouses of roses located in central region of Iran were surveyed toidentify the Botrytis cinerea. A total of 80 isolates were collected from rose greenhouses incentral region of Iran. Morphological identification was based on characters such asconidiophore and conidial length. Acco...

– A hierarchical fuzzy model is proposed in this paper. The concept of relevance has enabled the measurement of the relative importance of rule sets and the Separation of Linguistic Information Methodology (SLIM) provided a means to organize its information in different structures. Based on this methodology a new SLIM-PCS algorithm is proposed for the Parallel Collaborative Structure (PCS). As ...

This paper presents the structuring ideas behind the development of a multi-agent system. This system, BeLife, is a simulation tool with teaching objectives: (a) it intends to educate the core concepts behind the management of greenhouses and (b) it aims at fostering the understanding of experimentation in this particular context. The paper also describes a framework designed to support the cre...

Continuously Heated Greenhouses: A production or retail greenhouse with a constantly maintained temperature of 50 degrees F or more during winter months. Such greenhouse must also have a maintenance attendant on duty at all times or an adequate temperature alarm system to provide warning in the event of a heating system failure. In addition, the greenhouse roof material must have a thermal resi...
