Gravista(tm) Insecticide is a 3-in-1 product that combines a synergist, insect growth regulator, and adulticide into a single product. It gives knockdown power and prevents future generations from emerging. It is also available as Diacon(r) IGR PLUS.
Diacon(r) IGR PLUS and Gravista are two of the insect growth regulators (IGRs) currently available. Both were tested to determine whether they had residual efficacy. The study compared the effects of each pesticide on progeny production and physical grain damage.
Diacon IGR+ is a formulation of methoprene, deltamethrin, and piperonyl butoxide. It is used at a concentration of either 0.12 or 3.75 grams of AI per liter. It has been used to control populations of insect pests in grain fields and on concrete surfaces.
Gravista(tm) InsecTicide is an excellent choice for stored products, because it provides 3-in-1 control of stored product insect pests. This powerful product is effective against a broad range of insects, including sawtoothetles, red flour beetles, rice weevils, lesser grain borers, and more. Its unique formula features a synergist that provides an additional layer of protection. Moreover, it has no need for tank-mixing, which saves time and money for pest control. It can be applied directly on grain streams or as an empty-bin treatment.
Another key benefit of Gravista is its fewer active ingredients compared to other insecticides. By reducing the active ingredient in the insecticide, it will offer better protection against insects that have become resistant to other insecticides. It can also protect stored products for up to two years, and is considered safe for humans.
Juvenoid IGRs are synthetic compounds that mimic insect hormones. These compounds are effective in blocking the metamorphosis of insect larvae to adult insects. The mechanism by which they act is unclear, but they are believed to affect the growth and development of insects through signaling through a receptor in the insect’s cell called the JH receptor. Juvenoid IGRs were first discovered in the 1970s, and their biological activity was not understood until recently.
IGRs affect several important processes in the insect life cycle. For example, many insects undergo a dramatic metamorphosis. As a caterpillar, it spins a cocoon and develops into a pupa. IGRs can interfere with these processes and cause an insect’s eggs to never hatch.
In 1956, scientists found a compound that prevented Anopheles mosquitoes from undergoing metamorphosis and multiplication. While its possible use was unknown, researchers began to explore the potential of the substance after observing low hatch rates in linden bug cultures. They also found that the chemical disrupted the development of supernumerary instars and larval-pupal intermediates.
