6. Cerambycids as Plant Disease Vectors with Special Reference to Pine Wilt ......................... 209
Süleyman Akbulut, Katsumi Togashi, and Marc J. Linit

Preface
There are more than 36,000 described species in the family Cerambycidae worldwide. Although only a
small proportion of these species are pests in agriculture, forestry, or horticulture, their economic impact
is enormous, costing billions of dollars in production losses, damage to landscapes, and management
expenditures. A number of cerambycid species are important pests of various field, vine, and tree crops
as well as forest and urban trees in their native regions. However, with the substantial increase of inter-
national trade in recent decades, many cerambycid species have become established outside their natural
range of distribution, with the potential for causing enormous damage in these novel habitats. So far,
no comprehensive work dealing with all aspects of cerambycid biology and management from a global
viewpoint has been published.
This volume attempts to address that void by covering the entire spectrum from cerambycid classifi-
cation, biology, ecology, plant disease transmission to biological, cultural, and chemical control tactics,
to the world’s major agricultural and tree pests, invasive pests, and biosecurity measures. It is intended
to provide an entrance to the scientific literature on Cerambycidae for scientists in research institutions,
primary industries, and universities, and an essential reference for quarantine officers in governmental
departments charged with detection, exclusion, and control of cerambycids throughout the world. It is
hoped that this book will serve as a valuable reference work for many years to come.
This book is divided into 13 chapters, each of which covers a particular topic consisting of our cur-
rent knowledge and the gaps to be filled. Hundreds of examples, graphs, and photos are presented. The
book begins with an introductory chapter dealing with morphology of adults and immature stages, the
current classification system, the identification of adults and immatures to subfamily, and biology, global
diversity, and distribution of subfamilies. Chapter 2 discusses the types of habitats commonly occupied
by cerambycids; oviposition, fecundity, and egg development; voltinism, overwintering, quiescence, and
diapause; adult dispersal and longevity; and population dynamics in relation to environmental condi-
tions. Chapter 3 focuses on adult and larval feeding habits and wood digestion; flight, pollination, and
plant disease transmission in relation to adult feeding; larval host plant range and conditions, parts
and tissue utilized, and voltinism in relation to development and nutrition. Chapter 4 discusses adult
phenology and diet in association with host and mate location, mating and oviposition behavior, lar-
val development, and reproductive strategies. Historically, it was thought that cerambycids did not use
semiochemicals to mediate reproductive behaviors, but research over the past 15 years suggests that this
was erroneous, and that semiochemical use is very common if not ubiquitous within the family. Thus,
Chapter 5 summarizes recent research on cerambycid pheromones and their chemistry, the role of plant
volatiles as pheromone synergists, mechanisms for maintaining reproductive isolation, and applications
of pheromones and kairomones in pest management and detection of invasive pest species. Chapter 6
describes the biology and control of cerambycids as vectors of pathogens (nematodes) of the pine wilt
disease and plant–beetle–nematode interactions. Chapter 7 presents a thorough review of laboratory
rearing and handling of both cerambycid adults and immature stages with artificial and natural diets.
These are followed by three chapters on pest control tactics. Chapter 8 describes natural enemies in
relation to cerambycid life history, taxonomic range of natural enemies, impact of natural enemies on
cerambycid population dynamics, biological control approaches, and case studies. Using a number of
examples, Chapter 9 covers cultural control measures, including mechanical and sanitary techniques,
irrigation, plant density management, adjusting planting and harvest times, physical barriers, traps,
crop rotation and intercropping, plant resistance, and pest management in relation to climate change.
Chapter 10 discusses chemical control of cerambycid pests and provides a number of examples, cover-
ing the main classes of chemical insecticides and their field applications, including field sprays, bark
treatment, trunk injection and insertion, and soil and root treatment. Chapter 11 presents 43 selected
cerambycid species that illustrate the wide range of life history strategies found among cerambycids

infesting forest and urban trees throughout the world; information is provided on the identification of
adults, native and introduced geographic range, larval hosts, life history, economic impact, and control
options. In Chapter 12, 90 cerambycid species of economic importance in field crops, tree crops, and
vine crops from around the world are discussed along with their adult diagnoses, native and introduced
geographic range, damage, biology, and management measures. Chapter 13 deals with invasive ceram-
bycid pests and biosecurity measures, providing detailed information on interceptions and pathways
of invasive pests, inspection and detection methods, pest risk assessments, eradication programs, and
establishment and outbreaks of nonnative species.
Because of the nature of multiauthored contributions, it has not been possible to keep strict uniformity
in all chapters. The editor has tried, however, to adopt a uniform nomenclature for all cerambycid species
throughout the book. This has not been easy because the taxonomy of the Cerambycidae is still in flux,
and the recent synonymizations of several species are reflected in a few chapters. Although chapters are
logically linked, each represents an independent topic. Therefore, to keep the integrity of each chapter,
there is some overlap in subject matter in a few chapters.
The editor is indebted to many people for their advice during the preparation of this book, in particular
to Dr. J. Sulzycki, Dr. M. C. Thomas, Dr. T. A. Miller, J. J. Jurgensen, Jennifer Blaise, and to all of the
book’s contributors. This volume could not have been completed without the generosity of numerous
photographers, reviewers, and copyright holders, whose help is gratefully acknowledged in individual
chapters. I thank all of my family for their love and support, which have kept me going.

2 Cerambycidae of the World
1.1 Introduction
Cerambycidae Latreille, 1802, commonly known as longicorns, longhorns, longicorn beetles, longhorned
beetles, longhorned borers, round-headed borers, timber beetles, or sawyer beetles, are among the most
diverse and economically important families of Coleoptera. Taxonomic interest in the family has been
fairly consistent for the past century, but the description of new taxa has accelerated in recent decades.
The number of described cerambycid species in the world is about 36,300 in more than 5,300 genera
(Tavakilian 2015). The adult body length ranges from less than 2 mm in Cyrtinus pygmaeus (Haldeman)
(Linsley 1961) to greater than 170 mm in Titanus giganteus (L.) (Williams 2001). Cerambycids are widely
distributed around the world—from sea level to 4,200 m above—wherever their host plants are found.
Distribution and generic diversity of the world’s cerambycid subfamilies and tribes are shown in Table 1.1.
The longicorn adults are free-living beetles that may or may not need to feed. They can live for a few days
to a few months depending on whether they feed (Hanks 1999; Wang 2008). Cerambycids usually reproduce
sexually but, in very rare cases—such as in some species of Kurarus Gressitt (Cerambycinae) (Goh 1977)
and Cortodera Mulsant (Lepturinae) (Švácha and Lawrence 2014), they can reproduce parthenogenetically.
Švácha and Lawrence (2014) suggested that at least in Cortodera, parthenogenesis probably is of recent
origin because the female has a distinct spermatheca with a spermathecal gland. Mate location depends on
the occurrence and status of larval hosts, adult food sources, and/or pheromones. Hanks (1999) predicted
that the absence of feeding in the adult stage of many species is associated with the production of long-range
pheromones, but the current knowledge shows that the use of volatile pheromones is widespread in ceramby-
cids (see Chapter 5). The females lay their eggs on or near their hosts. The larvae of most cerambycid species
feed on woody plants, but some select herbaceous hosts. The vast majority of species at the larval stage are
living and feeding inside the plants although small minorities are free-living in soil and feed on plant roots.
Many cerambycid larvae are dead plant feeders and play a major role in recycling dead plants; others
attack living plants of different health states, ranging from stressed to healthy plants. To date, there are
about 200 cerambycid species worldwide that have some economic impact on agriculture, forestry, and
horticulture, causing billions of dollars of damage in production losses, environmental disasters, and
management costs. They may damage plants by direct feeding and/or transmission of plant diseases.

4 Cerambycidae of the World
With the increase of international trade in recent years, many cerambycid species have been intercepted;
some have become established outside their natural distribution range, causing serious problems globally
(Haack et al. 2010; see Chapter 13).
Linsley (1961, 1962a) and Wang (2008) summarize the general morphology and biology of the
Cerambycidae. More recently, Švácha and Lawrence (2014) have made a very detailed treatment of the
morphology and a general account of the ecology of the Cerambycidae. Ślipiński and Escalona (2013) gave
a good introduction to the morphology and ecology of Australian cerambycids. In this chapter, we summa-
rize the current knowledge about this family, including the definition and morphology, and a brief introduc-
tion to the taxonomy, distribution, and general biology at the subfamily level. We aim to provide readers
with a fundamental knowledge of cerambycids as well as a guide for those who may wish to consult specific
chapters in this book where detailed treatments of Cerambycid biology and pest management are discussed.
1.2.2.1 Adult
1.2.2.1.1 Diagnosis
General external morphology of cerambycid adults is illustrated in Figures 1.1 and 1.2. Antennae usually
filiform, elongate, and 11-segmented, rarely serrate and >12-segmented, usually inserted on pronounced
tubercles; eyes usually emarginate; prothorax without pleural sutures; tibia with two distinct tibial spurs;
tarsi usually pseudotetramerous with fourth tarsomere usually minute and concealed by third tarsomere;
elytra usually covering abdomen; hind wings with a spur on radio-medial crossvein; abdomen usually
with five visible sternites, fifth sternite entire.
1.2.2.1.2 Description
1.2.2.1.2.1 Head The head is prognathous and more or less horizontal in the Parandrinae (Figures 1.3
and 1.4). It is produced anteriorly to form a short to moderately long muzzle in some Lepturinae
(Figures 1.5 and 1.6), Dorcasominae, and Cerambycinae, inclined anteriorly in the Spondylidinae, and is
vertical or retracted, with the genal line directed posteriorly, in the Lamiinae (Figure 1.7). The eyes are
entire in the Parandrinae (Figure 1.3), most Lepturinae, and some Prioninae; feebly emarginate in the
Spondylidinae (Figure 1.8) and most Prioninae (Figure 1.9); emarginate to entire in the Dorcasominae;
and usually are deeply emarginate and reniform in the Cerambycinae (Figure 1.10) and Lamiinae
(Figure 1.7); although occasionally they are divided—as in Tetraopes Schönherr—or lacking the upper
lobe—as in Tillomorpha Blanchard. The facets of the eyes are large and coarse in the Parandrinae, most
Prioninae, and some Asemini and Cerambycinae; usually, they are finer in the Lepturinae, Lamiinae,
and more specialized Cerambycinae.
The antennae usually have 11 antennomeres (Figures 1.1 and 1.2) that are inserted near the base
of the mandibles in the Parandrinae (Figure 1.3), Prioninae (Figure 1.9), and in some Spondylidinae;

are near the eyes in the Asemini and Lepturinae (Figure 1.6); and are usually more or less embraced
by the eyes in the Cerambycinae (Figure 1.10) and Lamiinae (Figure 1.7). In some diurnal Lamiinae
(e.g., Octotapnia Galileo & Martins and Pseudotapnia Chemsak & Linsley) and Prioninae, the
antennae may have fewer antennomeres. In some Lamiinae (e.g., Paratenthras Monné), the first
three antennomeres are long, whereas the remaining flagella are reduced and sometimes moniliform.
The number of antennomeres may be 12 in a number of unrelated groups and more than 12 in a few
Cerambycinae and Prioninae (up to 30 in some species of Prionus Müller). The antennal structure is
similar between sexes in the Parandrinae, Spondylidinae, and Lepturinae, and strikingly dissimilar
in many Prioninae and in most Cerambycinae and Lamiinae. In the Parandrinae and Spondylidinae,
differentiation of antennomeres is not well marked; the scape is short, the second antennomere is
not greatly reduced in size, half as long as, or subequal to the third antennomere, and the segments
that follow are subequal in length. In the remaining subfamilies, the scape is usually more elongate,
the second segment is greatly reduced, and the following antennomeres are unequal in length—
with the third usually greatly elongated and those that follow diminishing to the ultimate antenno-
mere. The antennal segments are glabrous in the Parandrinae, Prioninae, and Spondylidinae, and are
pubescent in other subfamilies.
The labrum is fused with the epistoma in the Parandrinae and Prioninae but free in other subfami-
lies. The mandibles are acute in all of the Cerambycidae; large and often toothed in the Parandrinae
(Figure 1.4) and Prioninae (Figure 1.11); long, slender, and untoothed in the Spondylidinae; shorter
in most other groups; and are provided with a dense fringe of hairs in the inner margin of the
Dorcasominae and Lepturinae. The maxillae are typically bilobed; the inner lobe is obsolete in
the Parandrinae (Figure 1.12) and Prioninae (Figure 1.13). The ultimate segment of the palpi (both

Prioninae, and Spondylidinae. The mentum is distinctly transverse in the Parandrinae (Figure 1.20),
Prioninae, and Spondylidinae, and trapezoidal in the Lepturinae, Cerambycinae (Figure 1.18), and
Lamiinae (Figure 1.14). The ligula is corneous in the Parandrinae and Spondylidinae, and membra-
