  • Symbiotic Relationships

    the plant before the hornworm attacks. This is an indirect induced defensive and not constitutive because it is only when the saliva of the hornworm and even the rhythm of its munching is detected and processed in plant’s system, does it create these two chemicals (labeled Z and E in the article) in equal proportions which is exactly the signal for the predator, Geocoris spp. of the Hemiptera order, common name being big-eyed bug. One of these chemicals benefits the caterpillar by helping to protect it from infections because insects (such as myself) do not have immune systems like humans do but only immune responses. It takes this risk for this reward. Additionally, within a day the tobacco plant has its true induced direct chemical defense ready. Overall, the tobacco hornworm is not entirely specialized, as its name suggested but is also a generalist and maintains its role as a pest. With this many dangers, the tobacco hornworm is losing this battle. There is one last battle I shall show you, and it’s mine. If I haven’t mentioned it before, I hate parasitoids! As a green stink bug of the Hemiptera order, I have to watch out for an egg parasitoid (Tissoleus besalis).…

  • Diversity In Arthropod Communities

    Twenty-five samples of insect communities from each area were collected and comparisons were made amongst the diversity levels of the differing populations. Although, the species and subspecies of the arthropods found in both environments were quite similar, some insects were present in greater quantities in one environment as a result of the varying factors favoring the survival of the insect populations. The arthropods were divided into the following ten morphospecies; Spiders, Coleoptera,…

  • Dubas Bug Ommatissus Lybicus Case Study

    (Howard, 2001). O. lybicus is limited to P. dactylifera (monophagous insect) and found in almost all date palm plantations grown in Oman (Al-Khatri, 2011; Kinawy, 2012; Mokhtar and Al Nabhani, 2010). El-Haidari and El-Tijani, (1977) were first recorded the insect in Oman in 1962. It is also found in date palm plantations in many other countries including Pakistan (Shah et al., 2013), Iraq (Al-Jboory, 2007), Iran (Arbabtafti et al., 2014; Payandeh and Dehghan, 2013), Yemen (Ba-Angood, 2015),…

  • Importance Of Insects

    Insect biodiversity is very large and they are responsible for more than half of the population of eukaryote on the planet. It is approximately 900,000 species of insects have been described and recorded. Insects belong to phylum Arthropoda and class Insecta. Five orders of insects with high species richness include Hymenoptera, Diptera, Coleoptera, Lepidoptera and Hemiptera. Insects basic morphology are three pairs of legs, a segmented body divided into three (head, thorax and abdomen) or two,…

  • Importance Of Control Of The Cacao Tree

    pods are normally red or green in color. Green pods first turn yellow and then orange-yellow but red pods merely darken in color when they ripen. The surface of the pod may be smooth or crimped. The pod ripens 5 or 6 months after its fertilization. Cacao plant is a crop that highly suffers from severe attack by insects and yet at the same time depends on insects for the production of a crop. Harmful insects comprise many species but the prominent specie faced by the Kablon farm plantation are…

  • Case Study Of Theobroma Cacao

    It is because of the infestation form pest and disease and mostly the insect pest is brown cocoa mirid, Sahlbergella singularis. The percentage of yield loss will increase by next growing season. The initial of cocoa growing will loss 30% effected by infection of brown cocoa mirid and continuously increase up to 70% for the next growing seasons(2). So, in order to overcome this problem the several way should more highlight and identify the biggest factors that contribute the problem. Therefore,…

  • Porifer Animalia

    with a head, thorax, and abdomen, all completely covered by an exoskeleton made out of chitin; which is strong- yet flexible, provides protection, muscle attachment points that move appendages, and must be shed and secreted again, to permit growth (Myers, 2001e). Lastly, arthropods are classified as eucoelomates, with the coelom formed by schizocoely, which overall reduces the volume, and restricts portions of the reproductive and excretory system; thus, leaving most of the body cavity to be a…
