“…At these latter temperatures mortality also tended to occur during or within 48 h of molting as was observed at 10 and 37.8ЊC. High mortality at low and high temperature was reported previously for L. hesperus (Champlain and Butler 1967) and L. elisus (Bommireddy et al 2004) nymphs molting to adults, and for hatching eggs of L. lineolaris (Ridgway and Gyrisco 1960). Potentially, Lygus nymphs are more susceptible to desiccation during ecdysis and at temperature extremes.…”

Lygus hesperus Knight (Hemiptera: Miridae) is a key pest of fruit and vegetable crops, forages, and cotton (Gossypium spp.) in the western United States. Accurate models describing relationships between temperature and L. hesperus development are critical to the study of seasonal L. hesperus population dynamics. Development of L. hesperus nymphs was assessed at nine constant temperatures from 10 to 37.8 degrees C. The relationships between temperature and development for each L. hesperus instar, and for the entire nymphal stage, were best described by six-parameter biophysical models indicating both low- and high-temperature inhibition of development. Development rates asymptotically approached zero with decreasing temperature in the lower thermal range, and decreased with increasing temperatures above 32.2 degrees C. Nymphs did not survive from egg hatch to adulthood at either 10 or 37.8 degrees C, and nymph mortality was > 90% at both 12.8 and 35.0 degrees C. The fifth instar exhibited the longest stadium, whereas the shortest stadia were associated with the second and third instars. Development rates of males and females did not differ, and the ratio of males to females was not different from 1:1 at any temperature. Our temperature-dependent development rate models for L. hesperus nymphs will facilitate control of insect physiological age in controlled laboratory experiments, and should be useful in planning and interpreting field studies on L. hesperus population dynamics.

“…Nymphal developmental times of 2.55, 3.61, 3.36, 3.61, and 4.00 d (instars ÞrstÐÞfth, respectively) on green beans were similar to those reported by Butler and Wardecker (1971) for L. hesperus (2.8, 2.6, 3.0, 3.6 and 5.2 at 25ЊC; 2.4, 2.0, 2.2, 2.8 and 3.9 (instars Þrst-Þfth, respectively) at 30ЊC. Similar results were reported for L. lineolaris (Ridgway and Gyrisco 1960) and L. elisus (Bommireddy et al 2004). Although there were some slight differences between different development stages, the total nymphal development of L. lineolaris was Ϸ17 d at 27ЊC (Fleischer andGaylor 1988, Snodgrass andMcWilliams 1992), very similar to what we found in L. hesperus.…”

“…The total nymphal developmental time in green bean was 17.1 d at 27ЊC. These results were similar to a predicted developmental time obtained using a simple linear model constructed using data from the literature [17.2 d at 25ЊC for L. hesperus (Butler and Wardecker 1971), 13.6 d at 28ЊC for L. lineolaris (Khattat and Stewart 1977), 19.7 d at 25ЊC for L. lineolaris (Ridgway and Gyrisco 1960), and 20.7 d at 25ЊC and 14.3 d at 30ЊC for L. elisus (Bommireddy et al 2004)]. This analysis produced the equation: y ϭ Ϫ1.579x ϩ 47.907, with a moderately respectable R 2 of 0.71 and a marginally signiÞcant test for slope (P ϭ 0.07).…”

Laboratory studies were conducted to obtain basic biological information of Lygus hesperus Knight (Hemiptera: Miridae) on alfalfa (Medicago sativa L.), pigweed (Amaranthus palmeri S. Wats.), Russian thistle (Salsola iberica Sennen and Pau), green bean (Phaseolus vulgaris L.), artificial diet, and cotton (Gossypium hirsutum L.) square and cotton boll at 27 degrees C. The nymphal developmental duration was 28.8 d on cotton bolls, nearly twice longer, compared with approximately 15 d in other hosts. The nymphal survivorship was significantly lowest on the cotton boll (18%), whereas the survivorship in other hosts ranged from 33% (cotton square) to 93% (green bean). The average total nymphal survivorship was approximately 60% and the most nymphal mortalities occurred on the first three instars. The life-table parameters were obtained only in cotton square, artificial diet, green bean, and alfalfa. The average adult longevity in artificial diet was the shortest (18.7 d),with the longest longevity observed (36.1 d) on green beans. The intrinsic rates of population increase (r(m)) were much higher in artificial diet (0.0771) and green beans (0.0671) than in alfalfa (0.0327) and cotton square (0.0317). Although statistically significant, the difference in r(m) values between alfalfa and cotton square was very small, indicating the similarity in reproductive suitability of cotton square and alfalfain a no-choice test. Thus, even though cotton is not a preferred host, when blooming alfalfa and roadside weeds are mowed in the Texas High Plains during June-July, it is the most likely time that Lygus bugs may move from alfalfa and other host plants into adjacent cotton fields and become effective pest of actively fruiting cotton.

“…If soybeans were a good host, third instars could have been found in the sleeve cages after the 16-to 18-d periods in which the females were caged on the plants. If eggs were laid in soybeans on the Þrst day the females were placed in the cages, they would require an average 7.6 d to hatch at 25ЊC and 6.7 d at 30ЊC (Ridgway and Gyrisco 1960). Thus, if 7Ð 8 d for egg hatch occurred in the cages, there would have been an 8-to 10-d period for the development of nymphs in the cages before they were removed.…”

“…This ensured that most females were mated and ready to lay eggs when sleeve cages were infested. Mating of adults occurs between 4 and 6 d after becoming adults (Bariola 1969), and females have a preoviposition period of 8 d before they lay eggs (Ridgway and Gyrisco 1960). The adults were left in the cages in the Þeld for 16 d (17 June to 3 July 2005) on the preblooming soybean varieties in test 1.…”

Commercially produced maturity group (MG) IV soybeans, Glycine max L., were sampled during bloom for tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois), during May and June 1999 (3 fields) and 2001 (18 fields). The adults and nymphs were found primarily in single population peaks in both years, indicating a single new generation was produced during each year. The peak mean numbers of nymphs were 0.61 and 0.84 per drop cloth sample in 1999 and 2001, respectively. Adults peaked at 3.96 (1999) and 3.76 (2001) per sweep net sample (25 sweeps). Tests using laboratory-reared and field-collected tarnished plant bugs resulted in very poor survival of nymphs on 16 different soybean varieties (MG III, one; IV, four; V, nine; VI, two). A large cage (0.06 ha) field test found that the number of nymphs produced on eight soybean varieties after mated adults were released into the cages was lower than could be expected on a suitable host. These results indicated that soybean was a marginal host for tarnished plant bugs. However, the numbers of adults and nymphs found in the commercially produced fields sampled in the study may have been high enough to cause feeding damage to the flowering soybeans. The nature of the damage and its possible economic importance were not determined. Reproduction of tarnished plant bugs in the commercially produced early soybean fields showed that the early soybeans provided tarnished plant bugs with a very abundant host at a time when only wild hosts were previously available.
