Morphology and Adaptation of Immature Stages of Hemipteran Insects
© 2019 JETIR January 2019, Volume 6, Issue 1 www.jetir.org (ISSN-2349-5162) Morphology and Adaptation of Immature Stages of Hemipteran Insects Devina Seram and Yendrembam K Devi Assistant Professor, School of Agriculture, Lovely Professional University, Phagwara, Punjab Introduction Insect Adaptations An adaptation is an environmental change so an insect can better fit in and have a better chance of living. Insects are modified in many ways according to their environment. Insects can have adapted legs, mouthparts, body shapes, etc. which makes them easier to survive in the environment that they live in and these adaptations also help them get away from predators and other natural enemies. Here are some adaptations in the immature stages of important families of Hemiptera. Hemiptera are hemimetabolous exopterygotes with only egg and nymphal immature stages and are divided into two sub-orders, homoptera and heteroptera. The immature stages of homopteran families include Delphacidae, Fulgoridae, Cercopidae, Cicadidae, Membracidae, Cicadellidae, Psyllidae, Aleyrodidae, Aphididae, Phylloxeridae, Coccidae, Pseudococcidae, Diaspididae and heteropteran families Notonectidae, Corixidae, Belastomatidae, Nepidae, Hydrometridae, Gerridae, Veliidae, Cimicidae, Reduviidae, Pentatomidae, Lygaeidae, Coreidae, Tingitidae, Miridae will be discussed. Homopteran families 1. Delphacidae – Eg. plant hoppers They comprise the largest family of plant hoppers and are characterized by the presence of large, flattened spurs at the apex of their hind tibiae. Eggs are deposited inside plant tissues, elliptical in shape, colourless to whitish. Nymphs are similar in appearance to adults except for size, colour, under- developed wing pads and genitalia. 2. Fulgoridae – Eg. lantern bugs They can be recognized with their antennae inserted on the sides & beneath the eyes. -

These two psyllids are the only known vectors of the etiologic agent of citrus greening disease (Huanglongbing), and are the only eco- nomically important psyllid species on citrus in the world. Six other species of Diaphorina are reported on citrus, but these are non-vector species of relatively little importance (Halbert and Manjunath 2004). -

The neococcoids form a mono- phyletic group supported by both morphological and genetic data. In contrast, the monophyly of the archaeococcoids is uncertain and the higher level ranks within it have been controversial, particularly since the late Professor Jan Koteja introduced his multi-family classification for scale insects in 1974. Recent phylogenetic studies using molecular and morphological data support the recognition of up to 15 extant families of archaeococcoids, including 11 families for the former Margarodidae sensu lato, vindicating Koteja’s views. Archaeococcoids are represented better in the fossil record than neococcoids, and have an adequate record through the Tertiary and Cretaceous but almost no putative coccoid fos- sils are known from earlier. -

The impacts of pathogen-induced plant traits on vector preference are well studied in pathosystems but not in phytoplasma pathosystems. Therefore, the study of phytoplasma pathosystems may provide important insight into controlling economically important phytoplasma related diseases. In this study, we aimed to understand the impacts of a phytoplasma disease in palms on the feeding preference of its potential vector. We investigated the effects of a palm-infecting phytoplasma, lethal bronzing (LB), on the abundance of herbivorous insects. These results showed that the potential vector, Haplaxius crudus, is more abundant on LB-infected than on healthy palms. -

MF3001 Mealybug
i Mealybug Management in Greenhouses and Interiorscapes Mealybugs are major insect pests of greenhouse and interiorscape environments (including conservatories) where they feed on a wide range of plants and are difficult to manage (suppress) with insecticides. Host plant range depends on the particular mealybug species but includes herbaceous annuals or perennials, foliage plants, orchids, vegetables, and herbs. Specific plants include aglaonema, begonia, chrysanthemum, coleus (Solenostemon scutel- larioides), croton (Codiaeum variegatum), dracaena, false aralia (Dizygotheca elegantissima), ficus, grape ivy (Cissus rhombifolia), marigold, poinsettia (Euphorbia pulcherrima), pothos (Epipremnum aureum), and transvaal daisy (Gerbera jamesonii). A number of mealybug species may be found in green- Figure 3.
