A greenhouse test and two field tests were conducted to determine if a dye method of marking the fat body using Red Calco Dye could be used to identify adult tobacco budworms, Heliothis virescens (F.), and the bollworms, H. zea (Boddie), that had developed as larvae primarily on Geranium dissectum L. In a greenhouse trial, 73% of 22 adult tobacco budworms contained internal red dye after larvae fed on geranium plants treated with 10 ml of a dye mixture per plant (1% dye + 9% crude cottonseed oil + 90% water). No dye was detected in adults from larvae reared on untreated plants. One field was first infested with neonate tobacco budworms, and then treated with the dye mixture. Marked adults were caught in blacklight traps over a 13-day period. A second field of wild geranium, being ca. 11% of the total geranium in the immediate area, was treated with the dye mixture without artificial infestation. From the first to last marked adult caught in pheromone traps, 6.8% of the bollworms and 8.3% of the tobacco budworms contained internal red dye.

AbstractEfficiencies of light and pheromone traps were estimated from captures of moths emerging from pupae in the center of circular arrays of traps up to 200 m in radius. Light traps captured 1 insect for every 3.6 that passed through a linear meter at the trap, an efficiency factor of 0.28. This factor was constant for different insect densities. The pheromone traps were 3.5 times as efficient as light traps based on the captures of males only. The low efficiencies imply that the traps have a small zone of influence and several may be needed in a limited area to produce catches within reasonable confidence limits when populations are sparse and detection of increasing numbers has the greatest value.

The monitoring of the most dangerous noctuid pests (Lepidoptera: Noctuidae) can be performed by species specific pheromone traps. Recently the development of traps catching female moths became the main objective of the studies. We studied the synergistic effect of vine and beer as natural additive on the effectiveness of baits containing isoamyl alcohol and acetic acid in Forró and Debrecen-Ondód. The addition of vine and beer had positive effect on catches and it was significant in case of two dangerous pest species Agrotis segetum and Lacanobia oleracea. The synergistic effect was also significant with regard to the number of detected species especially in case of lower abundances and rare species.

Planting Season

Beet armyworm (Spodoptera exigua Hübner) (Lepidoptera: Noctuidae) is known to be a polyphagous insect that infests many crops such as welsh onion, maize, tobacco, cotton, and others. In Indonesia, this species is a major pest of shallot. The study was aimed to monitor the population of beet armyworm in the shallot plantation in Bantul Regency, Yogyakarta. The monitoring was conducted using pheromone traps containing Z-9-tetra decanol 10 µg/rubber unit and Z-9-tetradecadienyl 90 µg/rubber unit. The pheromone was placed in the fields to trap males during on- and off-shallot plant season. The sites for placing the pheromone traps were selected in the farms where shallot was planted once and twice per year. The selected sites were with shallot and non-shallot in their surrounding areas. The result showed that males emerged both on- and off-shallot planting seasons in most of the areas. The average number of trapped males during the shallot season was < 5 males/trap/week. The number increased and reached the peak (7.33 males/trap/week) in June until July which was the off-shallot season. The population reduced to < 2 males/trap/week at the end of second shallot planting season until end of the year where the fields were mostly planted with rice. These findings indicate that the beet armyworm presents all year around with or without shallot in the fields. It suggests that management of this insect should be done not only during the shallot season but also the remaining seasons to obtain more effectiveness.

Since invasion of Helicoverpa armigera (Hübner) in South America, identification of Helicoverpa species became essential for Integrated Pest Management (IPM). Thus, we worked out on a pictorial key to identify tree important Helicoverpa species that occur in the Southern Cone of America, using new morphological characters from the prothoracic legs. Adult male and female of Helicoverpa zea (Boddie), H. armigera, and Helicoverpa gelotopoeon (Dyar) were used for identification. Prothoracic legs from moths were removed and images were taken (magnification of 25X) with scales and specialized scales. In addition, images (magnification of 50X) of prothoracic legs were used to measure the foretibia and epiphysis. The results showed that measurable characters were more reliable and accurate on male moths than female moths. For this reason, we will show only detailed results of male moths. Foretibia of H. zea were longer than H. gelotopoeon, but shorter than H. armigera. This size is visible with or without scales and specialized scales on males. Here, we show a first detailed description of protibial epiphysis. H. armigera has the longest epiphysis with fore margin pointed and with bristles terminating before the end of epiphysis. This illustrated pictorial key shown some first detailed descriptions of prothoracic legs. These characters are useful on integrated pest management programs of many crops to identify male representatives of Helicoverpa, which are captured on pheromone traps.

Army Worm

Comparisons of traps for capturing fall army worm, Spodoptera frugiperda, baited with virgin females or synthetic pheromone were conducted at Dade County and Quincy, FL, Brownsville, TX, and Tifton, GA. Significantly higher numbers of fall armyworm males were captured in traps, irrespective of design, that were baited with a four - component lure, Terochem, than in identical traps baited with virgin females or a standard bait containing a 10 : 1 ratio of (Z) - 9 - dodecenol - 1 - ol acetate and (Z) - 9 - tetradecen - 1 - ol acetate. Wire - cone Hartstack traps baited with Terochem captured significantly more males than a plastic funnel - type Unitrap in two of three locations at Tifton, GA, during 1984 - 85, and at Quincy, FL, 1984. At Brownsville, TX, and Dade County, FL, the Unitrap baited with Terochem lures captured ca. as many or more fall armyworm males, respectively, than the Hartstack design. Standard green, yellow, and white Unitraps captured 2× more fall armyworm males than solid green Unitraps, suggesting that the color may influence rates of capture.

Heliothis virescens backcross moths are most effectively released in wide-area release programs from pupae placed in the field prior to moth emergence. A significantly greater moth emergence was obtained in the field from unharvested pupae in rearing trays than was obtained from harvested pupae. Mating, oviposition, and egg viability of emerged female moths were not adversely affected by handling procedures. Moths released from emergence containers were recovered in the most distant trap, 5.5 km, from the release point. However, the greatest number of released moths was captured in pheromone traps within 1.7 km of the release point.
