After 1983, the Standing Committee of State Council decided to stop the application of DDT in agriculture. Thereafter, DDT was mainly used as a raw material to produce Dicofol, with a small portion consumed as raw material to produce paints, as additives to produce mosquito-repellent incense, and to prevent malaria. The Chinese Center for Disease Control and Prevention (CDC) has decided that DDT can be used in closed systems and indoor sites in small amounts to control disease vectors, but its outdoor use is forbidden to prevent pollution. Malaria control in China has been effective, and DDT has not been used by local CDCs since 2001. The sale and consumption of DDT in 2001 and 2002 are shown in Table 3.4. It is seen that 83.9% of DDT produced was used to produce Dicofol 8.5% of that was exported for malaria prevention, 2.5% was used to produce mosquito-repellent incense, and 3.9% was used to produce paints. The investigation of consumption in 10 provinces and cities of China indicates that DDT is no longer used for agriculture or termite control, and a small portion of DDT is still used to prevent malaria. For example, 380 MT of DDT was used to control malaria between 1997 and 2000 in Yunnan province. 

Nevertheless, cellulose fatty esters with low DS values show other qualities, such as a high hydrophobicity. The development of water-repellent cellulosic materials (i.e., cotton, wood), has led to interesting applications in the textile and wood industries. For instance, the direct esterification of timber with fatty acids (and their derivatives) has resulted in extraordinary outdoor durability and resistance to biological attack (e.g. rotting, termites). Industrial exploitation of this technology has recently been conducted in France [WoodProtect by Lapeyre (Magne et al., 2003)]. In this case, the water-repellence conferred to wood and the lack of recognition from predator enzymes account for these properties. 

Conventional control of termites is heavily reliant upon prophylactic application of liquid insecticides to form a soil barrier around and beneath a structure to termite entry. These barriers, designed to repel or kill termites, degrade over time and must be reapplied every 5-10 years. A barrier termiticide application requires significant quantities of active ingredient, 5-10 kg, carried in 300 to 600 liters of water. Conventional products used as soil termiticides include organophosphates such as chlorpyrifos and isofenphos. 

Lippia javanica (Burm. f.) Sprang The essential oil of semi-dried leaves of L. javanica (1.6%) contained on average myrcenone 32%, ciy-ocimenone 32%, traui -ocimenone 16% as its major constituents. C/5-ocimenone changed into a more polar reddish-brown compound unless the oil was stored under freezing temperature conditions (79,80). In Kenya, an iirfusion of the leaves of L. javanica are used for treatment of stuffed nose, fever, malaria, tapeworm and for indigestion (36). The leaves are used to repel termites and other insects (48). 

New 2,6-dialkylated piperidines (207-210) have been isolated as cis/trans mixtures from the ant venom of Monomorium delagoense [487], Their structures were determined using MS, catalytic hydrogenation to the hydrocarbons, and methoxymercuration-demercuration followed by MS analysis. The structures of 207-209 were confirmed by synthesis of the cis/trans mixtures from the corresponding dialkyl pyridines. The major venom component, cis/trans 207, displayed potent insecticial activity against Reticulitermes worker termites (LD50 = 150 pg/g termite). In addition, 207 was a potent repellent for the ants Pheidole and Iridomyrmex [487],...

Analysing the chemical stimuli involved in a predator-prey interaction, Longhurst et al observed that specialized ants preying on termites emit non-repellent aliphatic alcohols as major components of the secretion from their mandibular glands whereas nonspecialized ants release aldehydes and ketones 550). 

A final example of an urban pest formulation with unusual needs is a slow-acting termiticide. The AI is consumed by termites from a bait station and taken back to the termite colony. The sharing of food within the termite colony is utilized to spread the AI throughout the colony. This results in elimination of the entire termite colony. In this case, the AI and formulation components must be well dispersed throughout the bait, with no repellency exhibited by the termites. 

Insects are more specific regarding their desires. Termites ingest wood or paper products as food sources. Baits for termites are usually treated wood chips, sawdust, or paper. Again, solutions, ECs, or SCs are usually the form of the AI used in preparing the baits. The AI is sprayed onto or mixed with the bait material, and then formed into a shape in a press or mold. Repellent adhesives and binders must be avoided, and these materials are prescreened for repellency prior to use in the bait.

Wood is susceptible to many forms of degradation, especially when it is exposed to fungi and insect species as termites, powder post beetles, and carpenter ants which are wood-destroying organisms. This was the original idea behind the development of wood preservatives by destroying wood-insects, and various chemicals have been used for wood treatment. The chemicals used extensively for wood protection and as insect repellents for wood preservatives include pentachlorophenol, arsenic... 

Larvae of certain insects, which feed on Pinaceae, ingest and sequester the lipophilic constituents, e.g., the abietic acid, of these plants and use them to repel predators (E 5.1). Carnosolic acid causes the characteristic bitter taste of Labia-tae. Geranylgeraniol, its acetate, and cembrene A are constituents of the pheromones of bees, ants, and termites, respectively. The andromedotoxins, e.g., acetylandromedol, are toxic compounds widespread in Ericaceae. They increase the constancy in pollination (E 5.5.1).
