75
circulatory system
dorsal vessel
76
dorsal vessel characteristics
- open at both ends
- composed of muscle cells that contract in a wave from tail to head
- this creates a vacuum that pulls in body fluid and makes a current
77
body fluid
hemolymph
78
hemolymph is composed of
cellular and non-cellular portions
cellular = hemocytes (12-15 different types)
non-cellular = water, amino acids, proteins, etc...
79
functions of hemolymph
- carry nutrients to tissues and organs
- carry hormones (molting)
- hydrolic fluid for insects with long appendages
- heat transfer
80
functions of hemocyte
- wound healing: fills cracks in cuticle
- phagocytosis: surround pathogen and kill with enzymes
- encapsulation: surround stores and stay there to prevent sporilation
81
#2 site for detoxification
hemolymph
82
\_\_\_\_\_ always kills the host
\_\_\_\_\_\_ don't
parasitoids always kill
parasites do not
83
3 main sites for detoxification
1- fat body
2- circulatory system
3- mid-gut
84
the chemical breakdown of food to components that can be absorbed into the body
digestion
85
functions of the foregut
prepare food for digestion
cuticular teeth at back of gut break down food
86
membrane at the opening of the mid-gut that expands with food
peritrophic membrane
87
peritrophic membrane functions
1- prevents damage to midgut cells
2- ADSORBS environmental chemicals
88
hind gut functions mainly for
water intake/reabsorption

96
basic unit of the nervous system
neuron
97
most neurons are...

synapse
101
complementary enzyme that gets rid of excess chemicals in synapse
acetycholinesterase
102

acetocholine
103
most insecticides work on the insect's...
nervous system
104
insecticides that work on the nervous system do so in 4 ways...
1- blocks ability of dendrite to pick up a stimulus
2- pre-synaptic
3- post-synaptic
4- inhibit broduction of complementary enzyme for neurotransmitter
105
hormone system that is closely related to the nervous system
endocrine system
106
2 major areas of hormone production
(new insecticides act on these glands)
1- corpora allata
2- corpora cardica
107
pre-synaptic pesticides...
inhibit neurotransmitter release
108
post-synaptic insecticides...
