Neoseiulus californicus was first reported in 1954 in California where it was collected from lemon trees (de Moraes et al. 2004). The predatory mite is distributed all over the world, both in arid and humid areas of sub-tropical and temperate zones. It was collected in Texas (USA), Mexico, Brazil, Guatemala, Peru, Argentina, Chile, Cuba, Colombia, Japan, Taiwan (introduced), Portugal, Italy, Fr...

A protocol for in vitro cloning of mature plants of Citrus limon using nodal shoot segments has been developed. Three to four shoots were induced per axillary meristems on MS medium amended with 9 μM BAP. Repeated transfer of the initial explants for up to six passages on MS medium [having 50% of the original concentrations of NH4NO3 and KNO3, and supplement of 250 mg L (NH4)2SO4] with 0.22 μM ...

Throughout the history of citrus production in Florida one of the diseases with a major impact has been the Asian form of citrus greening (HLB), which was first detected in 2005. As a response to this introduction, new survey and detection methods had to be developed utilizing field observations directed not only to corroborate symptoms already reported in the literature, but to describe any va...

This paper studies the impact of competition on the degree of inefficiency in lemons markets. More precisely, we characterize the second-best mechanism (i.e., the optimal mechanism with private information) in a stylized lemons market with finite numbers of buyers and sellers. We then study the relationship between the degree of efficiency of the second-best mechanism and market competitiveness...

Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), the fall armyworm is the most economically important maize pest in the western hemisphere. This research focused on the genetic variability of the maize host strain because there is a lack of information in this area of S. frugiperda research. Amplified fragment length polymorphism (AFLP) was used to assess the genetic variability of ...
