    Biocontrol of a perennial legume, Sesbania punicea, using a florivorous weevil, Trichapion lativentre: weed population dynamics with a scarcity of seeds (1991)

    Notes: Summary The establishment in South Africa of a florivorous, apionid weevil, Trichapion lativentre, on Sesbania punicea, a leguminous weed of South American origin, has reduced seed production of the plants by 〉98%. Surveys of the age structure and density of plants in infestations of S. punicea throughout South Africa have shown that the rate of recruitment of seedlings has drastically declined within a few years in many areas, due to the weevils. However, there has unexpectedly not been a corresponding decline in the density of mature plants in extant infestations of S. punicea. In spite of this, T. lativentre has curtailed the rate of spread of the weed into uninvaded habitats and has impeded reinvasion into areas cleared of infestations by mechanical means or by another complimentary biocontrol agent.

    Encapsulation of implanted foreign bodies by hemocytes in Locusta migratoria and Melolontha melolontha (1975)
    Springer
    Cell & tissue research 160 (1975), S. 283-289 
    Details
    ISSN: 1432-0878
    Keywords: Insect ; Hemocytes ; Capsules
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Sterile fragments of cellophane, cat-gut, cotton, or beef muscle implanted into the body cavity of Locusta migratoria and Melolontha melolontha are immediately surrounded by granular hemocytes which form a multi-layered capsule around each foreign body. The cytoplasm of the granular hemocytes of the outer zone of the capsule in both species shows an accumulation of fibrous material (microtubules and microfilaments). None of the implanted material appeared to be degraded.

    Role of the “thrombocytoids” in capsule formation in the dipteran Calliphora erythrocephala (1975)
    Springer
    Cell & tissue research 162 (1975), S. 343-348 
    Details
    ISSN: 1432-0878
    Keywords: Insects ; Hemocytes ; Capsules
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Of the three hemocyte types present in the blood of Calliphora, only one participates in capsule formation around implanted cellophane. This hemocyte, the thrombocytoid, shows in the blood a tendency to dissociate into numerous small cytoplasmic fragments, comparable to the mammalian megakaryocyte. This tendency is dramatically increased during the process of encapsulation. Most of the intact thrombocytoids and the numerous fragments participating in capsule formation do not show any particular modifications in their cytoplasm during this process, which corresponds to a mere sequestration of the implant. Dense material, resulting from necrotic cell debris and hemolymph lipoproteins, is often observed between the cellophane and encapsulating thrombocytoids, which apparently participate in the resorption of this material.
