White oil is an insecticide spray used for controlling a wide range of insect pests in the garden. The spray works by blocking the breathing pores of insects, causing suffocation and death. It is effective in the control of aphids, scale, mealybug, mites, citrus leafminer and other smooth skinned caterpillars. [1] "
Series from a study by Eisner and colleagues investigating defensive spray in bombardier beetles. The paper is specially treated to have a color reaction with the spray, which is normally clear. There are many strategies terrestrial arthropods employ in terms of chemical defense.
One can also spray the plants with water, or rinse the plants with a mild detergent/water solution (although caterpillars should be relocated before suds are applied). Scented detergents are acceptable; those containing OxiClean should be avoided. The aphids will turn black within a day, and eventually fall off.

Many crystal-producing Bt strains, though, do not have insecticidal properties. [5] The subspecies israelensis is commonly used for control of mosquitoes [6] and of fungus gnats. [7] As a toxic mechanism, cry proteins bind to specific receptors on the membranes of mid-gut cells of the targeted pests, resulting in their rupture.
Cupcakes baked with baking soda as a raising agent. Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3 −).
This week's theme 'Party week' treats saw the much-loved caterpillar cake take centre stage in the technical challenge. The cake took many forms on Tuesday's episode (14 November), with Matty's ...
Immediately after feeding the caterpillars return to the tent and aggregate in sunlight to facilitate the digestive process. Thus, eastern tent caterpillars are central place foragers. In contrast, the forest tent caterpillar is a nomadic forager that establishes a series of temporary resting sites during the course of its larval development.
