Hyadaphis foeniculi
Fennel Aphid
Hyadaphis foeniculi is a cosmopolitan aphid species and major pest of fennel (Foeniculum vulgare), native to Mediterranean regions and introduced to Brazil and other areas. Laboratory studies demonstrate strict thermal requirements: nymph development occurs only between 15-30°C, with 3°C and 33°C lethal. The species exhibits four nymphal instars with temperature-dependent development rates, completing the nymphal stage in 5 days at 30°C to 19 days at 15°C. Winged adults reproduce parthenogenetically, forming colonies inside fennel flowers during hot periods. The aphid vectors at least 12 plant viruses and produces honeydew that facilitates sooty mold growth, compounding crop damage.

Polistes dominula
European Paper Wasp
Polistes dominula is a highly successful invasive social wasp native to Eurasia that has established populations across North America, South America, New Zealand, South Africa, and other regions. First detected in North America near Boston in 1978, it has become one of the most abundant wasps on the continent. The species builds small, exposed paper nests in protected locations and preys primarily on live insects, particularly caterpillars. Unlike yellowjackets, it does not scavenge for meat or sugar. Its rapid spread has been attributed to ecological flexibility, superior competitive ability, and tolerance of human-altered environments.
