Answer: Safe for use in integrated pest management without harming beneficial insects, birds, and mammals.
- A Highly effective against essentially all agricultural pest species simultaneously and equally
- B Safe for use in integrated pest management without harming beneficial insects, birds, and mammals
- C Able to persist for considerably longer periods within the surrounding environment overall
- D Capable of being manufactured more cheaply than synthetic chemical pesticides generally
Correct answer: B. Safe for use in integrated pest management without harming beneficial insects, birds, and mammals
Explanation: The narrow host specificity of baculoviruses means they affect only the target pest species, leaving beneficial insects (pollinators, natural predators), birds, mammals, and humans unharmed, making them ideal for integrated pest management.
Sewage passes through physical removal (primary), then aerobic biological treatment where microbes form flocs that consume organic matter (secondary); the settled activated sludge is then digested anaerobically to produce biogas - a deliberate switch from aerobic to anaerobic conditions between stages.
