AbstractInfestations of pink bollworm, Pectinophora gossypiella (Saunders), (Lepidoptera: Gelechiidae), and numbers of beneficial insects in two cottons, Gossypium hirsutum, were compared at Maricopa, Arizona, and Brawley, California, during the 1986–1988 seasons. Plots (0.8 ha) of WC-12NL (nectariless, okraleaf, and early maturing) had significantly lower boll infestations than DPL-61 (nectaried, normal leaf, and later maturing) for each location and year. The three year average (range) PBW/100 bolls for WC-12NL and DPL-61 at Maricopa were 6.8 (5.7–10.7) compared to 11.2 (6.8–15.7), respectively. At Brawley the averages were 18.9 (9.3–27.6) compared to 39.2 (15.5–52.5), respectively. With the exception of 1986 at Maricopa, the percentage of bolls with eggs was significantly greater for DPL-61 (average 8.1, range 3.4–16.0) than for WC-12NL (average 4.2, range 1.1–12.1) for each location and year. Both cottons averaged about four eggs per oviposited boll; not significantly different. The numbers of Lygus spp. and three beneficial species of insects were not different in the two cottons. Collops vittatus (Say) (Coleoptera: Melyridae) was collected in significantly greater numbers in WC-12NL (1.0 per 50 sweeps compared to 0.9 for DPL-61), while Hippodamia convergens (Guérin-Ménéville) (Coleoptera: Coccinellidae) was collected in greater numbers in DPL-61 (0.6 per 50 sweeps compared to 0.3 for WC-12NL). WC-12NL is the culmination of a 20-year breeding programme for resistance to P. gossypiella and has characteristics attractive for cotton production in areas where a shorter growing season is desirable.

`Butterbowl' (NE-RBN-4) is a novel, small-sized (0.8 to 1.36 kg), flavorful (sweet), early maturing (90–95 days), near-oblate butternut type winter squash variety (Cucurbita moschata Duch. Ex Poir). No Butternut squash variety is similar in shape to `Butterbowl'. `Butterbowl' (S6) was derived from selfing a near-oblate open-pollinated S4 line derived from a cross of two true breeding crookneck lines (allelic test) NE-BNCR-67-1-7 (mutant out of `Butternut 23') X golden Cushaw (Agway Co.). Total fruit yield and fruit weight of `Butterbowl' were nearly similar to Butternut `Ponca'. The total fruit weight of'Waltham' was greater than `Butterbowl' in two out of four trials. The vining habit of `Butterbowl' (1.7 to 2.0 m) is more compact than `Waltham' or `Ponca'. `Butterbowl' is suitable for small gardens with limited space due to its compact plant habit. No crookneck fruit developed in `Butterbowl' in all tests. `Butterbowl' is resistant to bacterial spot, black fruit rot, and vine borer while it is moderately susceptible to powdery mildew. `Butterbowl' fruit should be used for consumption up to 45 to 55 days after harvest because slight fruit shriveling occurs at that time due to moisture loss. The fruit cooks uniformally in a microwave oven due to its more uniform flesh thickness.
