Applications made in late June 1998 provided the best mole cricket control compared to the other two field studies. The LC50 and LC90 values of thiamethoxam against adult southern mole crickets were 1,816 and 9,978 ppm, respectively, using a greenhouse bioassay technique. Another greenhouse study indicated that thiamethoxam at application rates ranging from 154 to 616 g (ai)/ha did not provide acceptable control against medium sized nymphs (third to six instars) of tawny and southern mole crickets. An additional study with fipronil, bifenthrin, and deltamethrin compared mortality of the two species of mole crickets in greenhouse bioassays. In these assays, all insecticides resulted in different levels of mole cricket mortality between the two species.

The two species are univoltine in most of their range. They also have similar life cycles and morphology. However, southern mole cricket is primarily carnivorous, whereas tawny mole cricket is herbivorous (Taylor 1979, Ulagaraj 1975, Matheny 1981). The African mole cricket, Gryllotalpa africana Palisot de Beauvois, is a world-wide pest (Sithole 1986). It damages plants including wheat, maize, rice, sorghum, millet, barley, oats, potatoes, cassava, groundnuts, strawberries, turnips, tobacco, and vegetables in Africa, Asia, and Europe. It also causes severe damage to turfgrass on golf courses in South Africa and Asia (Brandenburg, unpubl. data). Tsedeke (1979) reported that surface tunneling behavior, which is partly determined by feeding preference, is different between the two species in the U.S. We therefore speculate that tunnel architectures of three species are also different judging from the differences in their feeding behavior and damage. This study used fiberglass resins to compare tunnel architecture of three species of mole crickets in two locations Tawny and southern mole cricket tunnel castings were made on the driving range of Oyster Bay Golf Course, Brunswick County, NC, during 1998 to 2000. The turfgrass on the driving range was hybrid bermudagrass, Cynodon dactylon (L.) Pers. in sandy loam soil. African mole cricket tunnel castings were made in typical heavy clay soil at Silver Lakes Golf and Country Club, Pretoria, South Africa. The turfgrass on the fairway was Kikuyu grass, Pennisetum clandestinum Hochst. ex Chiov. We located mole cricket tunnel entrances by hand, and cleaned foreign matter, debris, and soil from the area around the entrance. We then used a soapy water flush (Short & Koehler 1979) as an irritant to flush the mole cricket from the tunnel for species identification. The soapy water flushing also helped to find other entrances to the tunnel and make the soil around the entrance firm. Areas without turf were avoided because the tunnels are often blocked by loose soil during the flushing. We have previously reported that fiberglass resin is the best material for mole cricket tunnel casting (Brandenburg et al. 2001). Bondo? fiberglass resin and hardener (Dynatron/Bondo Corp., Atlanta, GA), was used in the U.S. study and a similar product used in South Africa. This and other similar products are widely available at local hardware and automobile repair stores. Approximately 2/3 of the recommended amount of hardener was added to the fiberglass resin (about 1 ml hardener/100 ml resin). The fiberglass resin hardens quickly after adding hardener, therefore, the whole procedure must be done quickly. The fiberglass resin container was covered and shaken after adding hardener. The contents were then poured immediately into the tunnel entrance in a steady stream. The excavation of the castings started 1-2 h after pouring. The fiberglass resin in one can (1 1) usually filled two to three mole cricket tunnels. We used a large screwdriver to clear away the grass roots surrounding the tunnel entrance and to determine the direction of the casting before starting to dig the cast. Finding other entrance(s) of the tunnel helps to judge direction the tunnel casting. There are at least two entrances for tawny and African mole cricket tunnels. The soil on tunnel casts was washed away with water following excavation. We made over 100 castings and excavations during 3 years. Tunnels of tawny mole crickets were almost always (90%) in the shape of 'Y' with two entrances for each tunnel (Fig. IA, B, C). Variations were occasionally observed in the tunnel architecture. There might be two parallel 'Y's linking together to form a tunnel, or, two entrances observed at each end of a tunnel. The length of most tawny mole cricket tunnels ranged from 50 to 70 cm. Tunnels of African mole crickets also typically showed "Y" shape (Fig. 1G, H, I). The length of African mole cricket tunnels ranged from 10 cm to 23 cm. This was much shorter than that observed in tawny mole crickets. The tunnels of southern mole crickets were more likely in a reversed 'Y" shape with only one surface entrance (Fig. 1D, E, F). The tunnels often branched within 10 cm deep of the soil surface. The tunnels were usually much shorter than those of tawny mole cricket. The difference in tunnel architecture probably relates to the behavioral difference of the three species. Southern mole crickets are carnivorous. They seek prey throughout the soil. Our observations and research by Tsedeke (1979) suggested that southern mole crickets were much more active in tunneling than tawny and African mole crickets. This may be why southern mole cricket tunnels were almost always branched down into the soil rather than near the soil surface.

Two irrigation regimen tests using two rates of bifenthrin and lambda-cyhalothrin produced inconclusive results. Mole cricket damage ratings after the applications of bifenthrin (60 g [AI]/ha) and lambda-cyhalothrin (76 g [AI]/ha) were not significantly different among the four irrigation regimens (non-irrigation, irrigation before treatment, irrigation after treatment, and irrigation before and after treatment). Mole cricket damage rating after the application of bifenthrin (120 g [AI]/ha) under irrigation before and after irrigation was significantly better than those under other irrigation regimens at 14 and 21 d after treatment (DAT). Different irrigation quantity and irrigation timing (after insecticide treatment) did not significantly affect the performance of imidacloprid (434 g [AI]/ha) in the 1998 tests. However, the results from the 1999 test indicated that mole cricket damage ratings from the imidacloprid-treated plots were significantly different between 2 and 0.5 cm irrigation water after treatment at 21 and 28 DAT. Application of bifenthrin at a rate of 120 g (AI)/ha with 0.5 cm of irrigation water after treatment resulted in significantly lower mole cricket damage ratings than those of 1.0 and 2.0 cm of irrigation water after treatment at 30 DAT only in the 1998 test. Bifenthrin with irrigation at 1 h after insecticide treatment provided better mole cricket control than that of irrigation at 5 min after treatment at 30 DAT only in the 1998 test. Mole cricket damage ratings after application of bifenthrin were not significantly different between either irrigation quantity treatment or irrigation timing treatment in the 1999 tests. Possible effects of application timing, environmental conditions, irrigation practice, and insecticide physical properties on the results are discussed.}, number={3}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={Xia, YL and Brandenburg, RL}, year={2000}, month={Jun}, pages={852–857} }

Synthetic sucrose esters provided moderate to good insecticidal activity against tobacco aphids in laboratory evaluations. Octanoyl sucrose esters were most toxic, and decanoyl sucrose esters were least toxic to aphids. Only the octanoyl sucrose esters at a 2 mg/ml rate were as toxic to aphids as the natural sugar esters from Nicotiana gossei Domin. They were also the most effective synthetic sucrose esters against aphids when a CO2 hand-held sprayer was used. All of the synthetic sucrose esters demonstrated significantly higher aphid mortality at a rate of 2 mg/ml than at 1 mg/ml. Heptanoyl and octanoyl sucrose esters provided significantly higher aphid control under wet conditions than under dry conditions in the laboratory. Results from field tests were inconsistent. Field evaluations conducted in 1995 showed that the four synthetic sucrose esters were moderately toxic at a rate of 4 mg/ml using a CO2 hand-held sprayer and low to moderately toxic using a high clearance sprayer. The addition of a surfactant (Volpo G-31, Silwet L-77 or Volpo G-31 plus Silwet L-77) significantly improved the efficacy of octanoyl sucrose esters when a CO2 hand-held sprayer was used.
