Suborder Sternorrhyncha (Mealy Bugs, Scale Insects, Jumping Plant Lice, White-Flies, Aphid) Suborder Auchenorrhyncha (Cicadas, Leaf & Plant-Hoppers) Suborder Sternorrhyncha (Mealy bugs, Scale insects, Jumping plant lice, White-flies, Aphid) Suborder Auchenorrhyncha (Cicadas, Leaf & Plant-hoppers) These suborders include large and diverse groups of insects, different in shape. They are mostly small-sized, plant-feeding species, act as vectors of the plant diseases. Diagnostic characters: 1. Antennae very short (bristle-like, Auchenorrhyncha), in some insects long and filiform (Thread-like, Sternorrhyncha). 2. Wings usually slopping over sides of body at rest, some forms wingless, fore wings uniform in texture sometimes hardened than hind wings. 3. Base of sucking beak arising from back of head (Auchenorrhyncha), or when present, arising between front coxae (Sternorrhyncha). 4. Tarsi 1-3 segmented (3 segments in Auchenorrhyncha) (1-2 segments in Sternorrhyncha). 5. Metamorphosis usually gradual, sometimes complete in males, more rarely so in females.

  • The Planthopper Genus Trypetimorpha: Systematics and Phylogenetic Relationships (Hemiptera: Fulgoromorpha: Tropiduchidae)
    JOURNAL OF NATURAL HISTORY, 1993, 27, 609-629 The planthopper genus Trypetimorpha: systematics and phylogenetic relationships (Hemiptera: Fulgoromorpha: Tropiduchidae) J. HUANG and T. BOURGOINt* Pomological Institute of Shijiazhuang, Agricultural and Forestry Academy of Sciences of Hebei, 5-7 Street, 050061, Shijiazhuang, China t Mus#um National d'Histoire Naturelle, Laboratoire d'Entomologie, 45 rue Buffon, F-75005, Paris, France (Accepted 28 January 1993) The genus Trypetimorpha is revised with the eight currently recognized species described or re-described. Four new species are described and seven new synonymies are proposed. Within Trypetimorphini sensu Fennah (1982), evidences for the monophyly of each genus are selected, but Caffrommatissus is transferred to the Cixiopsini. Monophyly of Trypetimorphini, restricted to Trypetimorpha and Ommatissus, is discussed. A key is given for the following Trypetimorpha species: (1) T. fenestrata Costa ( = T. pilosa Horvfith, syn. n.); (2) T. biermani Dammerman (= T. biermani Muir, syn. n.; = T. china (Wu), syn. n.; = T. formosana Ishihara, syn. n.); (3) T. japonica Ishihara ( = T. koreana Kwon and Lee, syn. n.); (4) T. canopus Linnavuori; (5) T. occidentalis, sp. n. (= T. fenestrata Costa, sensu Horvfith); (6) T. aschei, sp. n., from New Guinea; (7) T. wilsoni, sp. n., from Australia; (8) T. sizhengi, sp. n., from China and Viet Nam. Study of the type specimens of T. fenestrata Costa shows that they are different from T. fenestrata sensu Horvfith as usually accepted, which one is redescribed here as T. occidentalis.

E, Riverside, CA 92501, USA dCollege of Life Sciences, Peking Univerisity, Beijing, China Received 5 May 2005; received in revised form 29 November 2005; accepted 29 November 2005 Abstract Glassy-winged sharpshooter, Homalodisca coagulata (Say), is an efficient vector of Xylella fastidiosa (Xf), the causal bacterium of Pierce’s disease, and leaf scorch in almond and oleander. Acquisition and inoculation of Xf occur sometime during the process of stylet penetration into the plant. That process is most rigorously studied via electrical penetration graph (EPG) monitoring of insect feeding. This study provides part of the crucial biological meanings that define the waveforms of each new insect species recorded by EPG. By synchronizing AC EPG waveforms with high-magnification video of H. coagulata stylet penetration in artifical diet, we correlated stylet activities with three previously described EPG pathway waveforms, A1, B1 and B2, as well as one ingestion waveform, C. Waveform A1 occured at the beginning of stylet penetration. This waveform was correlated with salivary sheath trunk formation, repetitive stylet movements involving retraction of both maxillary stylets and one mandibular stylet, extension of the stylet fascicle, and the fluttering-like movements of the maxillary stylet tips.

As principais características dos ‘Homoptera’ e dos Formicidae que favorecem as interações trofobióticas, tais como a excreção de honeydew por insetos sugadores, atendimento por formigas e necessidades fisiológicas dos dois grupos de insetos, são discutidas. Aspectos da sua evolução convergente são apresenta- dos. O sistema mais arcaico não é exatamente trofobiótico, as forrageadoras coletam o honeydew despejado ao acaso na folhagem por indivíduos ou grupos de ‘Homoptera’ não associados. As relações trofobióticas mais comuns são facultativas, no entanto, esta forma de mutualismo é extremamente diversificada e é responsável por numerosas adaptações fisiológicas, morfológicas ou comportamentais entre os ‘Homoptera’, em particular Sternorrhyncha. As trofobioses mais diferenciadas são verdadeiras simbioses onde as adaptações mais extremas são observadas do lado dos ‘Homoptera’. Ao mesmo tempo, as formigas mostram adaptações comportamentais que resultam de um longo período de coevolução. Considerando-se os inse- tos sugadores como principais pragas dos cultivos em nível mundial, as implicações das rela- ções trofobióticas são discutidas no contexto das comunidades de insetos em geral, focalizan- do os problemas que geram em Manejo Integrado de Pragas (MIP), em particular.

This feature has been exploited to reduce the expression of endogenous RNA for determining functions of various genes and for killing insect pests by targeting genes that are vital for insect survival. When dsRNA matching perfectly to the target RNA is administered, the RNAi machinery dices the dsRNA into ~21 bp fragments (known as siRNAs) and one strand of siRNA is employed by the RNAi machinery to target and degrade the target RNA. In this study we used a cocktail of dsRNAs targeting grape mealybug’s aquaporin and sucrase genes to kill the insect. Aquaporins and sucrases are important genes enabling these insects to maintain water relations indispensable for survival and digest complex sugars in the diet of plant sap-feeding insects, including mealybugs.

During the early 20th century agricultural depression in France, the wetland was more or less abandoned and started to become woodland.

Sharpshooter is a term commonly used to describe a group of leafhoppers in the family Cicadellidae. There have Like all true bugs, sharpshooters have piercing-sucking been several explanations for the use of this term. Riley mouthparts, which they use to tap into and feed upon and Howard (1893) first used “sharpshooter” to describe xylem or phloem (sap) tissue of plants. Most leafhoppers the feeding damage of the glassy-winged sharpshooter, have cryptic coloration (camouflage) and are often brown, Homalodisca vitripennis (Germar), on cotton.

They also reported “rapid and forcible ejection the tibia. The adults have two pairs of wings and are strong of minute drops of fluid” as another explanation for the use flyers. The nymphs of sharpshooters are wingless but are of this term. The term sharpshooter is also attributed to the capable of powerful leaps to search for food and to avoid hiding behavior of these insects when alarmed. Disturbed predators.
