Study Notes
True or False Statements
- A green toxic symbol indicates a chemical substance with a higher LD50 value, implying it requires a larger dose to be lethal to 50% of a test population.
- Cross-pollination in crops and the involvement of insects represents mutualism, where both parties benefit; this statement is false.
- Juvenile hormone, essential for regulating development and reproduction in insects, is naturally produced within their bodies.
- Diflubenzuron is incorrectly associated with being a chitin synthesis inhibitor; it actually functions as a growth regulator affecting chitin.
- Gossyplure, a synthetic sex pheromone, is wrongly attributed to Helicoverpa armigera; it is actually associated with different pest species.
- Tricogramma, a genus of parasitic wasps, targets insect eggs rather than larvae, debunking its classification as a larval parasitoid.
- Antixenosis refers to plant traits that deter insects from feeding, indicating a defensive mechanism rather than attraction.
- Insects generally exhibit a negative phototactic response, moving away from artificial light rather than towards it.
- Praying mantids primarily prey on adult insects, not specifically on larval stages of lepidopterans.
- Both naids (larvae of dragonflies) and adult dragonflies are well-known predators in their ecosystems, contributing to pest control.
Matching Exercises
- Oil of citronella is linked to juvenoids, compounds that mimic juvenile hormone effects.
- Allomone serves a role in chemical signaling between species, often used for defense or predatory success; Rachel Corsen is unrelated but may represent a figure in entomological studies.
- Juvabione is a compound with insecticidal properties, often categorized alongside microbial insecticides for controlling pest populations.
