Jim Dunn helped immensely with the experimental design and prevented me from giving up when my replication block was destroyed in a flood. Mathieu Ngouajio generously shared his expertise with organic vegetables, field trials and striped cucumber beetles. Mel Northup lent the HOBO weather stations, visited the farm to instruct me to set them up and later transferred the data into an Excel spreadsheet. Sango Otieno and the students at the Statistical Consulting Center at GVSU were very helpful with data analysis. Numerous farmworkers and volunteers also helped in the labor-intensive process of gathering data for this research. -
Squash Bug, Anasa Tristis
A Horticulture Information article from the Wisconsin Master Gardener website, posted 4 August 2008 Squash Bug, Anasa tristis The squash bug, Anasa tristis, is common pest found on squash and pumpkins throughout the United States. It will also occasionally feed on other curcurbits as well (cucum- bers, melons, and gourds). This shield-shaped insect sort of resembles a stink bug, but is a bit larger, more elon- gated and gray instead of green. Adult squash bugs are about 5/8” long. They are gray to black with orange and brown The squash bug, Anasa tristis, is a common stripes along the edges of pest of squash. the abdomen.

The elliptical eggs vary in color from tan to orange to brick red. They are laid in small clusters of a dozen or more, often in characteristic triangular or V shapes in the angles formed by leaf veins. The eggs get darker in color just before hatching in a week to 10 days. Reddish squash bug eggs are laid in clusters. The small nymphs have red heads and legs, and greenish bodies. As the nymphs age the red color Young nymphs have red legs and heads, while older nymphs are grey. They generally occur in groups. turns to black, and the older ones look like they are covered with a grainy gray powder. -
Anasa Tristis) Can Be a Serious Insect Pest for Organic Summer Squash Growers
EFFECTS OF COVER CROPS AND ORGANIC INSECTICIDES ON SQUASH BUG (ANASA TRISTIS) POPULATIONS by LINDSAY NICHOLE DAVIES (Under the Direction of David Berle) ABSTRACT Squash bugs (Anasa tristis) can be a serious insect pest for organic summer squash growers. The purpose of this research was to evaluate two methods to control A. tristis populations. The first experiment involved planting cover crops adjacent to summer squash in an effort to attract natural enemies to keep A. tristis populations in check. Natural enemies were attracted to the plots, but did not significantly reduce A. tristis populations. This may have been due to other food sources in the plots, such as pollen, nectar, and aphids. Also, summer squash yields were negatively affected by the cover crop treatments. The second experiment involved evaluating the efficacy of organic insecticides on A. tristis adults and nymphs. Results of this study showed pyrethrin-based sprays are best for controlling A. tristis.

Such symbioses have important applied implications when the associated insects are pests or vectors of disease. The squash bug, Anasa tristis (Coreoidea: Coreidae), is a significant pest of human agriculture in its own right and also causes damage to crops due to its capacity to transmit a bacterial plant pathogen. -
Egg Viability and Larval Penetration in Trichopoda Pennipes Pilipes Mohammad Shahjahan2 and John W. Beardsley, Jr.3 Trichopoda P
Vol. XXII, No. 1, August, 1975 '33 Egg Viability and Larval Penetration in Trichopoda pennipes pilipes Fabricius (Diptera: Tachinidae)1 Mohammad Shahjahan2 and John W. Beardsley, Jr.3 Trichopoda pennipes pilipes Fabricius was introduced into Hawaii from Trinidad in 1962 to combat the southern green stink bug, Nezara viridula (Fabricius) (Davis and Krauss, 1963; Davis, 1964). In Hawaii, T. p. pilipes has been reared from the scutellerid Coleotichus blackburni White and the pentatomids Thyanta accera (McAtee) and Plautia stali Scott, in addition to N. viridula. During 1965 we began a study on the biology of T. p. pilipes in rela tion to its principal host in Hawaii, N. viridula. Laboratory experiments and observations were conducted to evaluate the effects of superparasiti- zation of N. viridula by the tachinid on both the host and parasite pop ulations. The results of some of this work were reported previously (Shahjahan, 1968). The present paper summarizes data which were ob tained on parasite egg viability and larval penetration of host integument. The methods used in rearing and handling both N. viridula and T. p. pilipes were described in the earlier paper (Shahjahan, 1968). Supernumerary Oviposition and Egg Viability Adults of the southern green stink bug often are heavily superpara- sitized by T. p. pilipes, both in the field and under laboratory conditions. As many as 237 T. p. pilipes eggs were counted on a single field-collected stink bug, and a high of 275 eggs were deposited on one bug in the lab oratory (Shahjahan, 1968). Eggs are placed predominantly on the venter of the thorax, but may be deposited on almost any part of the host, in cluding the appendages, wings, eyes, etc. -
