Abstract
Plantation forestry is a significant component of forestry, particularly as a means to ensure sufficient availability of raw materials to support the wood-based industries in Sabah. Timber and timber-based products are important in contributing towards the socio-economic development besides generating revenue for the state. The monoculture forest plantations, however, are easily exposed to damages by insect pests. They are serious threat to the success of plantation forestry if not being monitored and managed properly. This publication on “An Introduction to the Insect Pests of Forest Plantations in Sabah” serves as a guide and reference to forest plantation stakeholders. The information compiled was based on research conducted by the Forest Research Centre of the Sabah Forestry Department in the past. The 160-page book features more than 65 insect pest species (including pest descriptions, symptoms and damages, and control measures), covering some 20 forest tree species. It was written in Malay to benefit the field staff in forest plantations.

Forest plantations are increasingly important as an alternative source for
timber and the trees, like other timber species, are not spared from insect pest
attack. Regular surveillance to collect pest information can help in the early
detection of potential problems and planning of effective approaches to
control the pests besides complying with the phytosanitary measures related
to timber trade. This host-pest list contains 332 insect pests recorded on 19
species of native and exotic fast-growing trees in Malaysia. Researchers,
plant biosecurity officers, plantation managers and those involved in the
timber trade may find this up-to-date list useful.
More than 19 insect species were recorded causing damage to Binuang. All are defoliators except one stem-borer. Many are new records. Information pertaining to the description, life cycle and other ecological data of the new records are provided. The occurrence of attack, economic importance, potential threat and management of Binuang insect pests are discussed.
Over 15 species of insects associated with Laran are discussed here. Many are new records. Information pertaining to the description, life cycle and other ecological data of the new records are provided. Some of the recent incidences of insect pest attack are also highlighted.
This book provides an illustrated introductory account of insects within the Heritage Amenity Forest Reserve in Sandakan, Sabah. It features mainly the commonly encountered insects while walking leisurely in the reserve. The publication is not intended to be technically comprehensive, documenting all insect groups, as this would be a daunting task involving various sampling methods, effort and time. Unlike plants, observing insects needs more effort, patience and interest because of their small size and mobility. Some are ingenuously camouflaged with the surroundings while others are cryptic in appearance.
A total of 9 species of insects associated with Red Laran are discussed here. Seven of them are defoliators while one is a stem borer and another a sap-sucking bug. Except for bagworms (Lepidoptera, Psychidae), the rest are new records. Information pertaining to the description, life cycle and other ecological data of the insects is provided. Control measures are also highlighted.
Insects defoliating Bornean endemic dipterocarp seedlings at the Sepilok nursery were investigated. A total of 12 insect species were documented as new records. Two defoliators were adult beetles while 10 were larvae of moths and butterflies. The most frequently encountered insect species was Clethrogyna turbata Butler (Lepidoptera: Lymantriidae), which occurred on four dipterocarp species. Due to its high abundance, the larva caused severe defoliation to Shorea symingtonii, S. waltonii and S. kudatensis seedlings. Defoliation caused by other insects was minor. Some notes on the new records are provided in this paper. The importance and management of insects associated with the dipterocarp seedlings are also discussed.
Tropical Forest Insect Pests promotes a better theoretical understanding of pest population dynamics, and causes of forest insect outbreaks in the tropics. Covering pests of both natural forests and plantations, it examines the diversity of tropical forest insects; their ecological functions; the concept of pests; and the incidence of pests in natural forests, plantations, and stored timber. General issues on which foresters and forest entomologists hold strong traditional views, such as the severity of pest incidence in plantations vs. natural forests, in plantations of exotics vs. indigenous tree species, and in monocultures vs. mixed plantations are discussed. The final section looks in detail at specific insect pests of the common plantation tree species across the tropics, with recommendations for their control. This is a comprehensive resource suitable for graduate students and researchers in forestry and tropical forest entomology, and for forest plantation managers in the tropics.
A search for characters to make the generic classification of Platypodidae more nearly objective resulted in the discovery of new anatomical features that appear to reflect patterns in phylogeny for this family. The Platypodidae are members of the Curculionoidea and are very closely allied to Scolytidae. Three subfamilies of Platypodidae are recognized: (1) Coptonotinae, containing Coptonotini (Coptonotus Chapuis, Protohylastes Wood, Scolytotarsus Schedl), Mecopelmini (Mecopelmus Blackman, Protoplatypus Wood), and Schedlarini (Schedlarius Wood [= Chapuisia Dugès]); (2) Tesserocerinae, containing Diapodini (Diapus Chapuis, Genyocerus Motschulsky [=Diacavus Schedl]), and Tesserocerini (Platytarsulus Schedl, Notoplatypus Lea, Tesserocranulus Schedl, Tesserocerus Saunders [= Damicerus Spinola, Tesseroplatypus Schedl, Tesserocephalus Schedl]), Spathidicerus Chapuis, Periommatus Chapuis [=Asetus Nunberg, Setanus Nunberg], Chaetastus Nunberg [=Symmerus Chapuis], Cenocephalus Chapuis, and Mitosoma Chapuis [=Platypicerus Nunberg, Coecephalonus Schedl]); and (3) Platypodinae, containing Platypodini (Platypus Herbst [=Cylindra Illiger, Stenoplatypus Strohmeyer, Platypinus Schedl, Austroplatypus Browne], Treptoplatypus Schedl, Crossotarsus Chapuis, Trachyostus Schedl, Neotrachyostus Browne, Platyscapulus Schedl [=Platyscapus Schedl, Costaroplatus Nunberg], Baiocis Browne, Cylindropalpus Strohmeyer, Triozastus Schedl, Mesoplatypus Strohmeyer, Doliopygus Schedl [=Scutopygus Nunberg, Pygodolius Nunberg, Mixopygus Nunberg, Mesopygus Nunberg], and 11 genera named as new to science derived from the genus Platypus of Schedl 1972. The following are new genera and their type-species: Peroplatypus (for Platypus truncatipennis Schedl), Dinoplatypus (for Platypus cupulatus Chapuis), Myoplatypus (for Bostrichus or Platypus flavicornis Fabricius), Oxoplatypus (for Scolytus or Platypus quadridentatus Olivier), Platyphysus (for Platypus obtusus Chapuis), Megaplatypus (for Platypus dentatus Dalman), Euplatypus (for Bostrichus or Platypus parallelus Fabricius), Epiplatypus (for Platypus desceptor Wood), and Teloplatypus (for Platypus concinnus Blandford). The archaic "Sektionen" used by Schedl in his 1972 classification of this family are eliminated. A key for the identification of genera, a discussion of characters, and remarks on phylogeny are included.
