Uses Chlorobenzene is used as a solvent and an intermediate in dyestuffs. o-Dichlorobenzene is used as a solvent, fumigant, insecticide, and chemical intermediate. Paradichlorobenzene is used as an insecticide, chemical intermediate, disinfectant, and moth-preventive agent. 

Tetrahydrofurfuryl alcohol is a solvent and coupling agent for a phosphate-type insecticide used to control the gypsy moth. Esters of tetrahydrofurfuryl alcohol are used in preparations employed as insect repeUents. Tetrahydrofurfuryl alcohol is also used as a solvent—carrier for an EPA-approved paper sHmicide formulation. In this appHcation, the exceptional solvent action of tetrahydrofurfuryl alcohol prevents separation of the...

Lepidoptera is the second largest insect group and includes nearly 150,000 described species, which have evolved over 100 million years since the Mesozoic era. For the birth of a new species, it must be isolated from other species by some factor to prevent inter-species crossing. The sex pheromone, which is secreted by the adult (usually by a female moth and sometimes by a male moth or butterfly) for the benefit of a specific partner, plays an important role in reproductive isolation. Therefore, it is no wonder that the chemical structures of the species-specific pheromones exhibit considerable differences. 

An aerosol formulation of the insect growth regulator hydroprene (Gen-trol) was labeled several years ago for use in the United States. There are no research reports with hydroprene aerosol, except for Bell and Edwards (1998), which describe a study conducted in Great Britain. In this study, aerosol applications of hydroprene (Protrol) prevented the development of eggs of the red flour beetle, T. castaneum, the confused flour beetle, T. confusum, and the almond moth, C. cautella, that had been placed in exposed dishes with food media.

Apple problems Aphids like to colonize tender shoot tips if they go unnoticed, it may become neoessary to prune out badly infested and distorted growth near right). A proteotive band far right) used to prevent wingless female winter moths from olimbing trees to lay their eggs, may also help with aphid problems—by keeping ants, which farm aphids, out of the tree. 

Relatively high concentrations of boron componnds are used to control fruitflies, cockroaches, gypsy moth larvae, houseflies, and woodboring insects (Sprague 1972 USEPA 1975 Table 29.6). Boric acid is an effective stomach poison for several insect species, including German cockroaches (Blattella germanica), that are unable to detect the presence of boric acid (USEPA 1975). Insect infestation of wood and other substrates can be prevented by pretreatment with boric acid or borax at... 

JUNVENILE HORMONES. One of several hormones, that retard the development of insects in the larval stage. So called because they prevent the insect from maturing by maintaining its juvenile characteristics. Obtained naturally from silk moths various syntheses indicate possible use as insecticides, especially for fire ants. Composition of one type is C18H30O3. 

Aldrin and dieldrin have never been produced industrially in China but were produced on a pilot scale for termite control. Endrin has never been produced in China. Both aldrin and dieldrin are agricultural pesticides, which can prevent the damage caused by soil insects, such as termites, locusts, moths in wood, etc. However, the Ministry of Agriculture has never approved the registration and use of aldrin and dieldrin as agricultural pesticides. The application of dieldrin was concentrated in... 

Present methods for the detection and population survey of spruce budworm rely on the sampling of egg masses on tree foliage. Pheromone traps could probably detect moths at lower densities than the present method and this information could be used to prevent or decrease the development of an epidemic infestation of spruce budworm. However, a great deal of work is still required to correlate trap capture with moth population densities and with damage to trees. 

C. M. Williams ( 1) prepared the first active extract from the cecropia moth and showed that this extract prevented adult development when applied to insect pupae. Treated pupae molted into morphogenetic monsters and died. Treatment of other stages produced no ill effects. From these studies it became clear that during the transformation of the immature insect into the adult (during the pupal stage) the juvenile hormones must be absent. This short developmental period is completely deranged when supplied with JH. 

PREVENTIVE. Severe codling moth infestation can often be seen in the vicinity of pallet box storage areas or warehouse compost heaps, if codling-moth-infested fruit have been left in the boxes or dumped together. In this case the fruits should be removed. 

In this method a cloud of the sexual attractant of the female codling moth is released in the orchard. In this cloud it is impossible for the males to find the female moths and mate with them. Production of progeny is thus prevented.
