Stink bugs are some of the worst pests in the vegetable garden. There are several different species and they attack and damage most vegetable crops by feeding directly on the fruit or developing seed with their piercing-sucking mouthparts. Brown stink bugs are often one of the first species to appear and they tend to be the most common species during the first half of the season. As the growing season progresses, they are joined by green stink bugs and southern green stink bugs, as well as some less common species of Euschistus. Damage is caused by both adults and nymphs, and stink bug populations can increase dramatically during the latter portion of the year due to a combination of in-garden reproduction and adult migration—a result of stink bugs moving out of agricultural crops that have become mature and are no longer attractive.
Brown stink bugs can be especially problematic on tomatoes and green beans during the earlier part of the season, and it may be necessary to treat these crops to prevent excessive damage. As the growing season progresses and stink bug populations increase, they can cause heavy damage to peas, beans and okra, as well as tomatoes, and it is often difficult to produce these crops without spraying for stink bugs. Fortunately, the insecticides used to control stink bugs on tomatoes are also effective against hornworms and tomato fruitworms.
Control: Pyrethroid insecticides such as zeta-cypermethrin (GardenTech Sevin Insect Killer) and permethrin (Hi-Yield Lawn, Garden, Pet & Livestock Insect Control and Bonide Eight Insect Control Concentrate are two examples) are the most effective treatments for stink bugs in home gardens. Pyrethroids are somewhat less effective against brown stink bugs than against the green stink bug species, but are still reasonably effective. Acetamiprid (Ortho Flower, Fruit and Vegetable Insect Killer) is a non-pyrethroid option, but it has a 7 day pre-harvest interval. Pre-harvest intervals vary depending on the product you use and the crop being sprayed, so check labels carefully before treating.
Other than hand-picking and foot-stomping, there are no good organic treatments for stink bugs. However, handpicking can help delay heavy population buildup in small-scale gardens, especially if gardeners are diligent to find and destroy as many adults as possible before they have a chance to lay eggs. See Extension Publication 2347, Insect Pests of the Home Vegetable Garden, for more information.

Brown Stink Bug, Buku la Kwanza Nambari tano. "Kama ilivyoelezwa katika makala ya ""Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti wa Utafiti." Kuna spishi kadhaa tofauti na wao kushambulia na kuharibu mazao mengi ya mboga kwa kulisha moja kwa moja juu ya matunda au kuendeleza mbegu na mouthparts yao piercing-sucking. Mara nyingi, wadudu wa rangi ya kahawia ni moja ya spishi za kwanza kuonekana na huwa ni spishi za kawaida zaidi katika nusu ya kwanza ya msimu. Wakati wa msimu wa kukua, wao ni alijiunga na kijani stink bugs na kusini kijani stink bugs, pamoja na baadhi ya aina ya kawaida ya Euschistos. Uharibifu husababishwa na watu wazima na nymphs, na idadi ya wadudu wa harufu mbaya inaweza kuongezeka sana wakati wa sehemu ya mwisho ya mwaka kutokana na mchanganyiko wa uzazi wa bustani na uhamiaji wa watu wazima - matokeo ya wadudu wa harufu mbaya wakiondoka kwenye mazao ya kilimo ambayo yamekomaa na hayanavutia tena. Vipepeo wa rangi ya kahawia wanaweza kuwa tatizo hasa kwenye nyanya na maharagwe ya kijani wakati wa sehemu ya mapema ya msimu, na inaweza kuwa muhimu kutibu mazao haya ili kuzuia uharibifu wa kupita kiasi. Wakati wa msimu wa kukua, idadi ya wadudu wa harufu mbaya huongezeka, na wanaweza kusababisha uharibifu mkubwa kwa maharagwe, maharagwe na okra, pamoja na nyanya, na mara nyingi ni vigumu kuzalisha mazao haya bila kunyunyizia wadudu wa harufu mbaya. Kwa bahati nzuri, dawa za kuua wadudu zinazotumiwa kudhibiti wadudu wa nyanya pia zina matokeo dhidi ya minyoo ya pembe na minyoo ya matunda ya nyanya. Pyrethroid, zeta-cypermethrin, na permethrin (Hi-Yield Lawn, Garden, Pet & Livestock, Bonite 8 Insect Control Concentrate) ni dawa bora za kuzuia wadudu wa mbuga. Pyrethroids ni kiasi fulani chini ya ufanisi dhidi ya bugs smell kahawia kuliko dhidi ya aina ya kijani stink bug, lakini bado ni busara ufanisi. Acetamiprid (Orthophthora) ni dawa ya kuua wadudu ya matunda na mboga, ambayo inaweza kutumika kwa muda wa siku 7 kabla ya kuvuna. Kipindi cha kabla ya kuvuna kinatofautiana kulingana na bidhaa unayotumia na mazao unayotumia, kwa hivyo angalia lebo kwa uangalifu kabla ya kutibu. Mbali na kuokota kwa mkono na kupiga miguu, hakuna matibabu mazuri ya kikaboni ya wadudu wenye harufu mbaya. Hata hivyo, kukusanya kwa mkono kunaweza kusaidia kuahirisha ongezeko kubwa la idadi ya watu katika bustani ndogo, hasa ikiwa wakulima ni bidii kupata na kuharibu watu wazima wengi iwezekanavyo kabla hawajawa na nafasi ya kuweka mayai.
