Pests of Trees and Shrubs Treehoppers Several species Order Hemiptera, Family Membracidae; treehoppers Native pests Host plants: Treehoppers are found on many tree species and are most commonly on young trees and perennial weeds. Oviposition damage caused by treehopper adult females. (241) Description: Treehoppers are small insects, usually less Photo: John Davidson than one-half inch long. They are called “treehoppers” because upon being approached they jump or hop away with a loud snap. They have a pronotum that is enlarged and developed into horns, knobs and other strange shapes. Males and females of the same species, however, can sometimes have very different pronotal shapes or colors. Life history: Adult females deposit eggs singly or in masses, either inserted directly into living tissue or on the surface of the plant. Females of some species cover their eggs with a frothy substance that hardens when dry. The eggs of most species remain in the plant through the winter and hatch in spring. Some adult females guard their eggs and remain with their young throughout their Treehopper adult. (242) development. Nymphs molt five times prior to reaching Photo: John Davidson the adult stage. Treehoppers usually have one or more generations per year. Overwintering: Eggs on host plants. Damage symptoms: Primary injury is caused by the females cutting into the bark to lay their eggs. Nymphs and adults also feed on plant tissue and suck cell fluids with their sharp, needle-like mouth parts. Monitoring: Monitor by hand sweeping young trees and shrubs with a net. Monitor for adults from early July to the end of October, or until the first frost. Chemical control: Dormant oil sprays can be used to kill overwintering eggs.

Ant–Treehopper Associations Deter Pollinators and Reduce Reproduction in a Tropical Shrub
Indirect effects of mutualism: ant– treehopper associations deter pollinators and reduce reproduction in a tropical shrub Javier Ibarra-Isassi & Paulo S. Oliveira Oecologia ISSN 0029-8549 Volume 186 Number 3 Oecologia (2018) 186:691-701 DOI 10.1007/s00442-017-4045-7 1 23 Oecologia (2018) 186:691–701 https://doi.org/10.1007/s00442-017-4045-7 PLANT-MICROBE-ANIMAL INTERACTIONS - ORIGINAL RESEARCH Indirect efects of mutualism: ant–treehopper associations deter pollinators and reduce reproduction in a tropical shrub Javier Ibarra‑Isassi1,2 · Paulo S. Oliveira1 Received: 22 September 2017 / Accepted: 10 December 2017 / Published online: 15 December 2017 © Springer-Verlag GmbH Germany, part of Springer Nature 2017 Abstract Animal-pollinated plants can be susceptible to changes in pollinator availability. Honeydew-producing treehoppers fre- quently occur on inforescences, potentially enhancing ant-mediated negative efects on pollination services. However, the efect of ant-attended, honeydew-producing insects on plant reproduction remains uncertain. We recorded the abundance of treehoppers and ants on Byrsonima intermedia (Malpighiaceae), and monitored foral visitors in a Brazilian cerrado savanna. We manipulated the presence of ants and ant–treehopper associations on inforescences to assess their efect on pollination and fruit formation. We used dried ants pinned to inforescences to evaluate the efect of ant presence and ant identity on potential pollinators. Results show that the presence of treehoppers increases ant abundance on fowers and disrupts pollination by oil-collecting bees, decreasing the frequency and duration of foral visits and reducing fruit and seed set. Treehopper herbivory has no direct efect on fruit or seed production, which are independent of treehopper density.

EXHIBIT I Management Procedures for Archaeological and Historical Sites and Properties on State-Owned or Controlled Lands Management Procedures for Archaeological and Historical Sites and Properties on State-Owned or Controlled Properties (revised February 2007) These procedures apply to state agencies, local governments, and non-profits that manage state- owned properties. A. General Discussion Historic resources are both archaeological sites and historic structures. Per Chapter 267, Florida Statutes, ‘Historic property’ or ‘historic resource’ means any prehistoric district, site, building, object, or other real or personal property of historical, architectural, or archaeological value, and folklife resources. These properties or resources may include, but are not limited to, monuments, memorials, Indian habitations, ceremonial sites, abandoned settlements, sunken or abandoned ships, engineering works, treasure trove, artifacts, or other objects with intrinsic historical or archaeological value, or any part thereof, relating to the history, government, and culture of the state.” B. Agency Responsibilities Per State Policy relative to historic properties, state agencies of the executive branch must allow the Division of Historical Resources (Division) the opportunity to comment on any undertakings, whether these undertakings directly involve the state agency, i.e., land management responsibilities, or the state agency has indirect jurisdiction, i.e. permitting authority, grants, etc. No state funds should be expended on the undertaking until the Division has the opportunity to review and comment on the project, permit, grant, etc. State agencies shall preserve the historic resources which are owned or controlled by the agency. Regarding proposed demolition or substantial alterations of historic properties, consultation with the Division must occur, and alternatives to demolition must be considered.

Social Behaviour and Life History of Membracine Treehoppers
Journal of Natural History, 2006; 40(32–34): 1887–1907 Social behaviour and life history of membracine treehoppers CHUNG-PING LIN Department of Entomology, Cornell University, Ithaca, NY, USA and Department of Life Science, Center for Tropical Ecology and Biodiversity, Tunghai University, Taichung, Taiwan (Accepted 28 September 2006) Abstract Social behaviour in the form of parental care is widespread among insects but the evolutionary histories of these traits are poorly known due to the lack of detailed life history data and reliable phylogenies. Treehoppers (Hemiptera: Membracidae) provide some of the best studied examples of parental care in insects in which maternal care involving egg guarding occurs frequently. The Membracinae exhibit the entire range of social behaviour found in the treehoppers, ranging from asocial solitary individuals, nymphal or adult aggregations, to highly developed maternal care with parent–offspring communication. Within the subfamily, subsocial behaviour occurs in at least four of the five tribes. The Aconophorini and Hoplophorionini are uniformly subsocial, but the Membracini is a mixture of subsocial and gregarious species. The Hypsoprorini contains both solitary and gregarious species. Accessory secretions are used by many treehoppers to cover egg masses inserted into plant tissue while oviposition on plant surfaces is restricted to a few species. Presumed aposematic colouration of nymphs and teneral adults appears to be restricted to gregarious and subsocial taxa. Ant mutualism is widespread among membracine treehoppers and may play an important role in the evolutionary development of subsocial behaviour. The life history information provides a basis for comparative analyses of maternal care evolution and its correlation with ant mutualism in membracine treehoppers.

Description of Damage (larvae and adults): Nymphs and adults alike feed by sucking the juices of the stems of the host plants, resulting in honeydew that allows fungus sooty mold to grow and turn the plant blackish in color. Severe infestations can result in reduced plant health with the death of twigs and branches. Also, slits are cut into the bark by the female’s saw-like ovipositor in order to lay eggs.
