Carnivorous plant to 30 °C to thrive. Carnivorous plants require appropriate nutrient-poor soil. Most appreciate a 3:1 mixture of "Sphagnum" peat to sharp horticultural sand (coir is an acceptable, and more ecofriendly substitute for peat). "Nepenthes" will grow in orchid compost or in pure "Sphagnum" moss. Carnivorous plants are themselves susceptible to infestation by parasites such as aphids or mealybugs. Although small infestations can be removed by hand, larger infestations necessitate use of an insecticide. Isopropyl alcohol (rubbing alcohol) is effective as a topical insecticide, particularly on scale insects. Diazinon is an excellent systemic insecticide that is tolerated by most carnivorous plants.
What Work Is What Work Is What Work Is is a collection of poetry by Philip Levine. The collection has many themes that are representative of Levine's writing including physical labor, class identity, family relationships and personal loss. Its primary focus on work and the working class led to it being studied with emphasis on Marxist literary criticism. The focus on work is expressed in thematically different ways throughout the collection. Furthermore, much of the collection was shaped by concerns for blue collar workers as well as nationwide political events. "What Work Is" was first published in 1991 by Alfred A. Knopf, Inc.
