PEAR RUST MITE CONTROL ON PEARS, 2004

The cereal rust mite, Abacarus hystrix, cannot be used for biological control of quackgrass

Quackgrass, Elymus repens (L.) Gould, is a perennial grass spreading by vigorous underground rhizomes. Because of its capacity for rapid spread and persistence, it is considered as a common weed in many settings worldwide. The cereal rust mite, Abacarus hystrix (Nalepa), is a polyphagous, phytophagous mite attacking quackgrass and many other grasses including wheat. Its feeding causes leaf disc...

Hall et al.: Citrus Rust Mite & the Negative Binomial 1 CITRUS RUST MITE (ACARI: ERIOPHYIDAE) COUNTS ON FRUIT AND THE NEGATIVE BINOMIAL DISTRIBUTION

Count data for the number of citrus rust mites per cm 2 on fruit across a 4-ha (10acre) area of orange trees followed the negative binomial probability distribution 79% of the time based on chi-square tests. A correlation of r = 0.993 was found between observed counts and counts projected based on the distribution. A common k of 0.149 was computed but generally appeared more suitable for mean d...

On Control Flow Hijacks of unsafe Rust

Rust is a newly designed systems programming language that aims at safety. However, as a systems language, Rust must be able to manipulate rawmemory and interact with native C codes freely. In this project, we demonstrate how the use of unsafe keyword can potentially undermine the security guarantees of Rust. Specifically, we provideworking demonstrations to show that in some circumstances, vul...

How Many Pears Would a Pear Packer Pack if a Pear Packer Could Pack Pears at Quasi-exogenously Varying Piece Rates? An Empirical Investigation of Inter-temporal Labor Supply1 PRELIMINARY AND INCOMPLETE. DO NOT CITE OR CIRCULATE WITHOUT AUTHORS’ PERMISSION

We examine the labor supply of fruit packers using a unique, panel dataset collected from a large California-based pear packing plant. The data consist of both worker-day level payroll data, along with data from a field collection effort that generated worker-minute level performance data. Workers face both expected and unexpected shocks to their wages, and we use this to evaluate different mod...
