PDF-Classical biological control of arthropods in the st

S Hoddle Department of Entomology University of California Riverside California USA INTRODUCTION The first attempt by man at classical biological control of an arthropod pest was a spectacular success The cottony cushion scale Icerya purchasi Maskel. Sommerer imple classical systems can be so unpredictable both quantitatively and qualitatively that they appear random If there is a true source of randomness in such a system the situation can be even more puzzling This counterintuitive behavior ri We put livings things into two large groups:. Animals . Plants. Vertebrates. These are animals with a backbone.. There are five groups of vertebrates:. Amphibians. Birds. Fish. Mammals. Reptiles. Amphibians. 24.1 Arthropod Diversity. Arthropods characteristics. invertebrates. exoskeleton (cuticle) made of chitin. jointed appendages (paired). segmented body parts. Arthropod Groups. Trilobites. extinct, bottom feeders. Arthropods and Echinoderms. Includes animals such as crabs, spiders, and insects. Segmented bodies, a tough exoskeleton (external body covering) and jointed appendages (legs and antennae that extend from the body wall). A Presentation by. W.D. McIlveen. Biological Control Review.
