The completion of this project would have been impossible without help from so many different quarters and the few lines of gratitude and acknowledgements written out in this section would do no justice to the actual amount of support and encouragement that I have received and that has contributed to making this study a successful endeavor. I am indebted to Prof. Meier for motivating me to embark on my PhD (at a very confusing point for me) and giving me a chance to explore a field that was quite novel to me. I express my sincere gratitude to him for all the guidance, timely advice, pep talks, and support through all the stages of this project and for always being patient while dealing with my ignorance. He has also been very understanding during all my non- academic distractions in the last two years.

  • INSECTS of MICRONESIA Diptera: Coelopidae (Phycodromidaey
    INSECTS OF MICRONESIA Diptera: Coelopidae (PhycodromidaeY By D. ELMO HARDY UNIVERSITY OF HAWAII AGRICULTURAL EXPERIMENT STATION This is the first report of the occurrence of the family Coelopidae in the Pacific region other than the subarctic, subantarctic, and New Zealand areas. The United States Office of Naval Research, the Pacific Science Board (National Research Council), the National Science Foundation, and Bishop Museum have made this survey and the publication of the results possible. Field research was aided by a contract between the Office of Naval Research, Department of the Navy, and the National Academy of Sciences, NR 160-175. The drawings were prepared by Marian S. Adachi, University of Hawaii. The coelopids are moderate-sized, conspicuously hairy flies which breed in kelp, and perhaps in other seaweed, washed up on the shore. The adults can be collected in large numbers by sweeping seaweed along the beaches. The group is almost restricted in distribution to cold and temperate regions of the world. Aldrich (1929, U. S. Nat. Mus., Proc. 76: 1) writing of North Amer­ ican species of Coe1opa s. 1. says "... all of the spp. appear to breed in the kelps and are found only on seashores where seaweeds of this group are washed up." The discovery of a species in the western Caroline Islands greatly extends the known range of the family. The members of this family, as defined by Hendel [1928, Tierwelt Deutsch­ lands 11 (2) : 89], are characterized by having the prelabrum produced; the genae swollen (bulging); the body depressed, the postvertical bristles well developed and convergent; the tibiae with preapical dorsal bristles, the median pair crossed; the subcostal vein complete, and the costa not broken.

  • History of Taxonomy
    History of Taxonomy The history of taxonomy dates back to the origin of human language. Western scientific taxonomy started in Greek some hundred years BC and are here divided into prelinnaean and postlinnaean. The most important works are cited and the progress of taxonomy (with the focus on botanical taxonomy) are described up to the era of the Swedish botanist Carl Linnaeus, who founded modern taxonomy. The development after Linnaeus is characterized by a taxonomy that increasingly have come to reflect the paradigm of evolution. The used characters have extended from morphological to molecular. Nomenclatural rules have developed strongly during the 19th and 20th century, and during the last decade traditional nomenclature has been challenged by advocates of the Phylocode. Mariette Manktelow Dept of Systematic Biology Evolutionary Biology Centre Uppsala University Norbyv. 18D SE-752 36 Uppsala E-mail: [email protected] 1. Pre-Linnaean taxonomy 1.1. Earliest taxonomy Taxonomy is as old as the language skill of mankind. It has always been essential to know the names of edible as well as poisonous plants in order to communicate acquired experiences to other members of the family and the tribe. Since my profession is that of a systematic botanist, I will focus my lecture on botanical taxonomy. A taxonomist should be aware of that apart from scientific taxonomy there is and has always been folk taxonomy, which is of great importance in, for example, ethnobiological studies. When we speak about ancient taxonomy we usually mean the history in the Western world, starting with Romans and Greek. However, the earliest traces are not from the West, but from the East.

The larvae were grown on two different species of seaweed, Laminaria digitata and Fucus serratus. The aim was to gain knowledge on the influence of feeding media on the growth and composition of the larvae. F. serratus was more nutrient-dense than L. digitata, being richer in both protein and lipids, and thus led to ~70% higher larvae growth. The larvae grown on F. serratus also had higher lipid and protein content than the larvae grown on L. digitata; F. serratus-grown larvae had ~8-9% protein and ~18% lipid (total fatty acids) (both values of dry matter), while the larvae grown on L.

  • Observations on Antennal Morphology in Diptera, with Particular Reference to the Articular Surfaces Between Segments 2 and 3 in the Cyclorrhapha
    © The Author, 2011. Journal compilation © Australian Museum, Sydney, 2011 Records of the Australian Museum (2011) Vol. 63: 113–166. ISSN 0067-1975 doi:10.3853/j.0067-1975.63.2011.1585 Observations on Antennal Morphology in Diptera, with Particular Reference to the Articular Surfaces between Segments 2 and 3 in the Cyclorrhapha DaviD K. Mcalpine Australian Museum, 6 College Street, Sydney NSW 2010, Australia abstract. The main features of antennal segments 2 and 3 seen in the higher Diptera are described, including many that are not or inadequately covered in available publications. The following terms are introduced or clarified: for segment 2 or the pedicel—annular ridge, caestus, chin, collar, conus, distal articular surface, encircling furrow, foramen of articulation, foraminal cusp, foraminal ring, pedicellar button, pedicellar cup, rim; for segment 3 or the postpedicel—basal foramen, basal hollow, basal stem, postpedicellar pouch, sacculus, scabrous tongue, sub-basal caecum; for the stylus or arista—stylar goblet. Particular attention is given to the occurrence and position of the pedicellar button. The button is the cuticular component of a chordotonal organ, which perhaps has the role of a baroreceptor. It is present in the majority of families of Diptera, and possibly was present in the ancestral dipteran. Some generalizations about antennal structure are made, and a diagram showing the main trends in antennal evolution in the Eremoneura is provided. The general form of the antenna shows a transition from approximate radial symmetry (e.g., in Empis, Microphor, and Opetia) through to superficial bilateral symmetry (in many taxa of Eumuscomorpha), though there is usually much asymmetry in detail.

  • Assessment of Insect Invaders of Decaying Banana and Plantain (Musa Spp .) Pseudo Stems in Umuagwo, Ohaji – Egbema Local Government Area, Imo State, Nigeria
    84 Agro-Science Journal of Tropical Agriculture, Food, Environment and Extension Volume 9 Number 2 May 2010 pp. 84 - 89 ISSN 1119-7455 ASSESSMENT OF INSECT INVADERS OF DECAYING BANANA AND PLANTAIN (MUSA SPP .) PSEUDO STEMS IN UMUAGWO, OHAJI – EGBEMA LOCAL GOVERNMENT AREA, IMO STATE, NIGERIA. Nwosu, L .C. and Lawal, I. A. Department of Science Laboratory Technology, the Federal Polytechnic Ede, Osun State, P.M.B. 231, Ede Osun State, Nigeria . ABSTRACT Insect invaders of decaying banana and plantain pseudo stems in Umuagwo, Ohaji-Egbema, Imo State were investigated in randomly selected crop plots near living homes (<500 m) and far from living homes ( ≥500m). Investigation was done by the use of trapping systems, dissections of cut decaying pseudo stems and culturing of immature stages of insects to adulthood. A total of 10 insect orders of economic and medical/veterinary importance were sampled. Members of the orders Coleoptera 903 (39.50%) and Diptera 692 (30.27%) were more prevalent. The remaining 30.23% were members of orders Hymenoptera 252 (11.02%), Dictyoptera 115 (5.03%), Orthoptera 85 (3.72%), Isoptera 69 (3.02%), Dermaptera 59 (2.58%), Hemiptera 43 (1.88%), Collembola 41(1.79%) and Siphunculata 27 (1.18%). The result of this study also showed that the number of insects found in banana and plantain pseudo stems in plots near homes 1085 (47.46%) did not significantly differ from those found in plots far from living homes 1,201 (52.54%) [P (Z>1.78) = 0.0375]. This suggests that site of crop plot has no obvious impact on the abundance of insect invaders of banana and plantain pseudo stems.

Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock.

  • Adaptations of Insects Teacher’S Booklet
    Adaptations of Insects Teacher’s Booklet Texas Cooperative Extension Part of the Texas A&M University System Molly Keck Extension Program Specialist 3355 Cherry Ridge, Suite 212 San Antonio, TX 78230 Email: [email protected] Preface Insects have amazing adaptations that make each type unique and diverse. Insects are adapted for life in every environment imaginable. With the exception of deep in volcanoes, insects can be found everywhere. Insect adaptations include mouthparts, the ability to fly, leg types, and body shapes. Imagine if all insects looked exactly the same, ate exactly the same food, and lived in exactly the same habitats. It would be impossible because insects would compete too much and would not be able to survive. In this booklet are a variety of exercises designed to help educate your students about adaptations by using insects as examples. 1 Table of Contents Preface 1 Lesson 1 – Insect Adaptations 3 Activity 1 – Maze 7 Lesson 2 – Insect Mouthpart Adaptations 8 Activity 2 – Insect Masks 11 Lesson 3 – Insect Adaptations to Habitats 18 Activity 3-1 – Matching Legs to Habitats 22 Activity 3-2 – Build an Insect 24 Lesson 4 – Who is Adapted to Their Environment 29 Activity 4-1 – Adaptation Matching Game 33 Activity 4-2 – Adaptation Word Search 35 Wrap Up Group Activity 36 Wrap Up Crossword Activity 37 Glossary 39 Lesson 1 - Insect Adaptations Overview: Students will read the following passage in the classroom and then answer relevant questions pertaining to the passage.
