Solar　insecticidal　lamps　(SIL)　can　effectively　control　pests　and　reduce　the　use　of　pesticides.　Combining　SIL　and　Internet　of　Things　(IoT)　has　formed　a　new　type　of　agricultural　IoT,　known　as　SIL-IoT,　which　can　improve　the　effectiveness　of　migratory　phototropic　pest　control.　However,　since　the　SIL　is　connected　to　the　Internet,　it　is　vulnerable　to　various　security　issues.　These　issues　can　lead　to　serious　consequences,　such　as　tampering　with　the　parameters　of　SIL,　illegally　starting　and　stopping　SIL,　etc.　In　this　paper,　we　describe　the　overall　security　requirements　of　SIL-IoT　and　present　an　extensive　survey　of　security　and　privacy　solutions　for　SIL-IoT.　We　investigate　the　background　and　logical　architecture　of　SIL-IoT,　discuss　SIL-IoT　security　scenarios,　and　analyze　potential　attacks.　Starting　from　the　security　requirements　of　SIL-IoT　we　divide　them　into　six　categories,　namely　privacy,　authentication,　confidentiality,　access　control,　availability,　and　integrity.　Next,　we　describe　the　SIL-IoT　privacy　and　security　solutions,　as　well　as　the　blockchain-based　solutions.　Based　on　the　current　survey,　we　finally　discuss　the　challenges　and　future　research　directions　of　SIL-IoT.
