The responsibility of the Commanding Officer is to ensure _____
the Senior Enlisted Medical Department Representative (MDR) and hospital corpsmen responsible for pest control are certified in shipboard pest control.
The Senior MDR ensures _____
an ongoing shipboard pest control
program is maintained.
Vessels with no assigned MDR
shall obtain technical consultation
and assistance from their _____
cognizant preventive medicine
personnel or the NDVECC or NEPMU.
Navy Medical Entomologists
assigned to Navy Disease Vector
Ecology and Control Centers (NDVECCs) and Navy Environmental and Preventive
Medicine Units (NEPMUs) is responsible for
overseeing the shipboard pest control program
The German cockroach, Blatella germanica
Most commonly encountered pest aboard Navvy ships. a small, flattened, light brown insect which can be easily identified from other cockroaches (Fig. 2-2) by the presence of two dark longitudinal stripes behind the head (“Lieutenant’s bars”).
True or false. If two or more cockroaches per trap are caught in a 24-hour period, pesticide treatment may be necessary.
True
True or false. A high-level of sanitation is the first step to effective cockroach control.
True
The four key factors that support cockroach infestations are?
Food, water, warmth, harborage
True or false. The shipboard pest control specialist should conduct a cockroach survey every two weeks in food service areas, and weekly until cockroaches are no longer present.
True
Dermestid Beetles
Hairs on the outside of the larvae can cause intestinal trauma, eye irritation, dermatitis and allergic reactions. Recognized by the
characteristic patterns of various
colors on their wing covers.
The Khapra Beetle,
Trogoderma granarium
Has become a quarantinable insect of
medical importance worldwide. The adults and larvae are generally
brown in color and covered with
yellowish hairs. In contrast to other
dermestid species, it feeds on grains and cereal products, instead of animal products. An infestation of one or more living or dead larvae of Trogoderma or other dermestid
species shall be justification for
condemnation of the lot
Flour Beetles
The red flour beetle, Tribolium
castaneum, and the confused flour
beetle, Tribolium confusum
Both species are common pests of
crackers, cereals, flour, and other
grain products. When present in large numbers, both species cause flour to turn gray in color and impair its baking qualities. Adult flour beetles also secrete benzoquinones.
Because of this, a tolerance level of only 3 or more insects per pound for
Tribolium infestations is lower than
the limit of 7 or more insects per
pound requirement for most other
insects
Saw-toothed Grain Beetle
The most common SPP aboard
ship. It can infest a wide range of
commodities including grain
products, dried fruits, candy, sugar,
dried meats, and tobacco products.
The adult is slender, flat, and brown.
It is easily recognized by the six sawtoothed- like projections on each side of the thorax.
Rice Weevil
Considered to be one of the most
destructive of the stored products
pests, feeding on a variety of raw
grains and grain products. A
characteristic long “beak” or ”snout”
that extends down under the head.
Indian Meal Moth
Plodia interpunctella
a worldwide distribution and is the
number one pest of dried fruits in
storage. The fully-grown larvae are
large compared to other common
SPPs (about one-half inch long).
The most commonly seen “white
worms” found in packaged dried
fruits are nearly always the larvae of
this moth. They also produce silk
webbing, which further lowers the
quality of the infested commodity.
The adults of this moth have a
grayish band across the upper 1/3 of their reddish-bronze wings.
Cigarette Beetle
The adult is light-brown in color and
appears rounded. The head is bent
downward, giving the insect a
strongly humped appearance. The
last segments of the antennae are
serrate or triangular, and the
hardened front wings are smooth in
appearance.
The drugstore beetle
Very active and will eat almost anything. The adult is reddishbrown
in color. In contrast to the cigarette beetle, the last 3 segments of the antennae are elongated and
sausage-like in shape. The front
wings have parallel lines along their
length. Its life history and habits
resemble the cigarette beetle.
Book-lice Liposcelis
divinatorius
common and often extremely abundant in stored grain products. Minute insects about the size of a pinhead. Preferred foods are molds and fungi
Reporting Infestations of SPPs
DD Form 1222
Preserving at least two
specimens in _____(or isopropyl alcohol, if ethyl alcohol is unavailable)
70 percent ethyl alcohol
adult moths should be
submitted ___, or carefully placed into
folded postage envelopes.
dry in vials without alcohol
MIL-STD-904B (Appendix G) lists
the following thresholds for
determining fitness for human
consumption of commodities infested
with SPPs.
· One or more dermestid larva(e),
adult(s), or cast skin(s) per lot.
· Three or more Tribolium larvae or
adults (i.e., flour beetles) per
pound of product.
· Seven or more of any other
insects (larvae or adults) per
pound of product.
Fumigation aboard
ship is conducted only under
special circumstances and
requires the approval of a _______
Navy Medical Entomologist.
The Norway rat, Rattus norvegicus
“common rat,” “brown
rat,” water rat,” or “sewer rat”
It is associated with diseases such as
tularemia, spotted fever and bubonic
plague. It is a comparatively large
aggressive rat, brown-gray above,
gray on the underside, and weighs
approximately 7 to 17 ounces.
Roof Rat
The “roof rat,” “ship rat,” or “black
rat,” Rattus rattus
the roof rat is far more common on ships than the Norway rat. It weighs 4-13 ounces, with its tail length (6-10”) greater than half its total body length (13-18”).
The house mouse, Mus musculus
a small rodent, adults
weighing only about ¾ ounce, with a total length of 5-8”. It is gray-brown above and below. It is commonly associated with humans and may cause serious damage to electrical wiring or food stores, especially sweets and grains.
Routes frequently traveled by
rodents are called ______
"runways."
True or false. Because the odor from dead rats in confined spaces of a ship is unacceptable, rodent trapping is the
prescribed method for rodent control
True. Use of poison baits must be approved by the cognizant Medical Entomologist at a NDVECC or NEPMU.
Decontaminate the surface of
infested packages with a
household bleach ___ tablespoons
household bleach per gallon of
water) or other sanitizer
3 Tablespoons
True or false. Place unset baited
traps in the trapping location for a
few days before actually setting
the spring and trigger.
True. This gives the rodent a false sense of security as it becomes used to the location of the trap and
available food.
Bed bugs, Cimex species
bloodsucking insects which feed on
sleeping hosts. Bed bugs are oval-shaped and flat
(when not engorged with blood).
Adults are approximately 7 mm long. They appear brownish in color, are wingless, and have piercing-sucking mouthparts
Human Lice
Three types of sucking lice are
important parasites of humans: the
body louse, the head louse, and the
crab louse.
The Body Louse, Pediculus
humanus humanus
responsible for transmitting louseborne
typhus, trench fever, and relapsing fever.
The Head Louse, Pediculus
humanus capitus,
The most important diagnostic
characteristic is the presence of
eggs, or nits, in the hair
The Pubic Louse (Crab Louse),
Pthirus pubis
small grayish-white insect with a
broad abdomen and large second
and third pairs of legs, giving it a
crab-like appearance.
Filth Flies
The common house fly and other
species such as flesh flies and blow
flies
Biology
One of the most striking aspects of
these insects is their ability to
multiply rapidly under ideal
conditions.
Fruit Flies
Fruit flies are attracted to yeast
produced by fruits and vegetables as
they ripen and decay. At least one
species is also attracted to human
and animal feces and may serve as
a vector of disease. If ingested,
some may cause stomach upset and diarrhea
